D-Wave <b>Quantum's</b> Energy Pitch Attracts Big Money Amid Overheated Rally

D-Wave Quantum's Energy Pitch Attracts Big Money Amid Overheated Rally 19.04.2026 - 19:41:49 | boerse-global.deThe staggering energy demands of artificial intelligence are creating an unexpected opportunity for quantum computing firm D-Wave Quantum Inc. While AI data centers consume power on an industrial scale, D-Wave’s systems require a mere 10 kilowatts, a contrast CEO Alan Baratz is leveraging as a key selling point. This narrative, coupled with a strategic nod from chip giant Nvidia, has ignited a furious rally in the stock, drawing in institutional investors even as technical indicators flash warnings of a pullback. Shares of D-Wave skyrocketed approximately 55% over a recent five-day period, briefly pushing past $22 from around $14. The surge was partly triggered by Nvidia's release of open-source AI models named "Nvidia Ising," designed to advance quantum technology. Nvidia CEO Jensen Huang stated these models correct quantum computer output errors three times faster than conventional methods. Investors interpreted this move as an indirect validation of the quantum computing sector, with D-Wave emerging as a primary beneficiary on massive trading volume. The rally has now captured the attention of professional money managers. In a required filing dated April 18, asset manager Massachusetts Financial Services Co. established a new position, acquiring roughly 42,600 D-Wave shares worth over $1 million. This institutional entry signals growing credibility, even as the company sports a lofty market capitalization of about $8 billion against a still-niche revenue base. That revenue, however, is projected to grow explosively. Management forecasts sales for fiscal year 2025 will jump 179% to $24.6 million. The company also anticipates an 82.6% gross margin, though it expects an adjusted EBITDA loss of $71.8 million. Perhaps most striking is the projected growth of its sales pipeline for 2026, which is forecast to expand by roughly 1,500% year-over-year. Should investors sell immediately?

Oil jumps, stock futures fall as tensions rise and US fires shots at Iranian ship in Strait of Hormuz

Oil jumps, stock futures fall as tensions rise and US fires shots at Iranian ship in Strait of Hormuz The state of the war in Iran is at its most tenuous point since the ceasefire began. If there’s one thing we know about the war in Iran, it’s that things can change quickly. This weekend was a perfect example. As trading opened on Sunday evening, oil prices soared and stock futures dropped, as the situation in the Strait of Hormuz deteriorated. Brent crude futures were up 6% at about 6:35 pm ET, while S&P 500 futures were off 0.8%. After a Friday where markets surged and oil prices dropped as both the US and Iran declared the strait open, American investors woke up to news on Saturday that Iran’s military said the strait had “returned to its previous state.” A UK maritime authority said it had gotten word of a tanker coming under Iranian fire near Oman. Ships were turning back. Then Sunday night, things got even more heated: President Trump and US Central Command said the US had opened fire on an Iranian ship that had, after hours of warnings, defied the US blockade of its ports. The US said Marines had seized the ship. The Associated Press, citing Iranian state-run media, said Iran vowed a swift response. A US delegation led by Vice President JD Vance is reportedly still expected to resume peace talks with Iran this week in Pakistan, but today, the war appears to be at its most tenuous point since the ceasefire between the two countries was announced April 7.

India's Public Banks Face <b>Quantum</b> Encryption Mandate and High Costs | Whalesbook

Preparing for Quantum Computing Threats The finance ministry's directive for public sector banks (PSBs) to explore quantum-resistant encryption is critical for India's financial sector. It pushes banks to prepare for a future where quantum computing could break today's strongest encryption quickly. Experts project "Q-Day," the point at which quantum computers can break current cryptography, to arrive as early as 2029, with broader consensus pointing to the mid-2030s. State Bank of India, the nation's largest lender with a market capitalization nearing ₹1 trillion, is already collaborating with IIT Jodhpur on tackling phishing apps. Punjab National Bank is focusing on "Quantum-Proof Systems for Public-Facing Applications," while UCO Bank is developing audio forensics to combat voice cloning fraud. These individual efforts are amplified by national initiatives like India's National Quantum Mission, which has a ₹6,003.65 crore outlay and aims to establish a 2,000-km quantum communication network by 2030-31. The mission has already demonstrated a 1,000-km secure communication network, showcasing indigenous technological advancements. Global Race and India's National Quantum Mission India is not alone in this push for quantum readiness. Major global financial firms, including JPMorgan Chase, Goldman Sachs, Barclays, HSBC, and Mastercard, are testing quantum-safe encryption methods. This global race highlights the importance of post-quantum cryptography (PQC) for protecting sensitive data and transactions. Regulators in the US, Europe, and the G7 are also urging banks to enhance computing infrastructure security, targeting critical systems by 2030. Indian PSBs are entering this domain with varying financial profiles. SBI, with a P/E ratio around 11-12 and a market cap of approximately ₹1 trillion, appears to be valued moderately. PNB trades at a lower P/E of around 7-8, reflecting a market capitalization of roughly ₹131,000 crore. UCO Bank, with a market cap of about ₹33,500 crore, has a P/E ratio around 12-13, indicating a similar valuation to

Time running out to protect Bitcoin from <b>quantum computers</b>, Google says | RNZ News

Google has issued a wake-up call to the Bitcoin community to take urgent action to upgrade blockchain security as advances in quantum technology increase the risk of fraudulent transactions and theft. Google recently published a white paper warning that quantum computers were already technically capable of intercepting and stealing Bitcoin during an active transaction. University of Auckland professor of mathematics Steven Galbraith (an associate member of New Zealand's Dodd-Walls Centre for Photonic and Quantum Technologies) said the risk was real but not immediate. "There is no evidence that anyone has a quantum computer that can do anything right now," he said. Why the urgency? While the risk might not be immediate, bad actors were already harvesting dormant assets, to decrypt later. "So if someone's interested in your medical data, they can harvest it now by just monitoring what's being sent over the Internet, and then they can just store that on hard disk," Galbraith said. "And then whenever they get a quantum computer in the future, they will be able to decrypt that. And so that's one of the reasons why people are being encouraged to start switching to the post-quantum cryptography (PQC). Why Bitcoin's blockchain is at particular risk Nobel-prize winning physicist John Martinis who helped build Google's quantum computers said the research showing how a quantum computer could break Bitcoin encryption in minutes should be taken seriously. While there was an industry solution to protect data using PQC, it was expected to take years to fully implement and upgrade vulnerable assets, though about 20 percent of internet traffic was already protected. Galbraith said systems that were regularly upgraded by big tech and banks were moving in the right direction, but legacy systems, which did not receive regular security updates, such as Bitcoin's blockchain, were at risk. While the

Adam Back says Bitcoin safe despite 2029 <b>quantum</b> talk

Adam Back says Bitcoin safe despite 2029 quantum talk Bitcoin developer and Hashcash creator Adam Back has responded to concerns raised by Nic Carter regarding a possible quantum computing milestone in 2029. - Adam Back rejects claims that 2029 quantum computing threatens Bitcoin’s cryptographic security. - Google quantum timeline seen as research milestone, not practical tool for breaking Bitcoin encryption. - Bitcoin developers work on post-quantum upgrades including new secure address and signature systems. Carter had suggested that advances in quantum systems could challenge Bitcoin’s cryptographic security. Back dismissed the concerns during recent comments, stating that software protection continues to improve alongside hardware developments. He also responded to claims that Bitcoin could become exposed to quantum attacks, noting that current fears are based on future assumptions rather than present capability. Back said ”2029 is a milestone in cloud quantum systems, not a tool for breaking cryptography” when referring to Google’s research direction, according to the discussion referenced in reports. Quantum computing and Bitcoin security outlook The discussion centers on whether quantum computing could generate enough processing power to break Bitcoin private keys. Experts cited in the debate note that this would require millions of stable logical qubits with full error correction. Current quantum systems remain in early development stages and operate under controlled laboratory conditions. These systems are not yet capable of performing cryptographic attacks at scale. Back stated that most projections place such capability beyond the current decade, based on limitations in hardware stability and error correction progress. Moreover, work on post-quantum cryptography within the Bitcoin ecosystem is already ongoing. Developers are testing upgrade paths that could introduce quantum-resistant address types. These proposals include research linked to upgrade paths such as BIP-361 and similar signature schemes. The aim is to allow users to move funds to new address formats

News | IonQ Achieves Key Photonic Interconnect Milestone | Pipeline Publishing

IonQ Achieves Key Photonic Interconnect MilestoneIonQ Achieves Key Photonic Interconnect Milestone, Demonstrating Networked Quantum Systems Using EntanglementAs part of a joint project with Air Force Research Laboratory, IonQ constructs first networked quantum systems among remote quantum processing units. [Case Number: AFRL-2026-1742]IonQ announced it has achieved a foundational technical milestone by photonically interconnecting two independent trapped-ion quantum systems. This achievement marks the first demonstration of connected, commercial quantum computers, a critical step toward scaling quantum computation beyond a single processor. By successfully linking two remote quantum systems, IonQ has validated the generation, transmission, and detection of photons used to enable quantum entanglement between two commercial IonQ computers at a distance for the first time. This major commercial result reinforces prior lab demonstrations and the theory of using photonic links to interconnect separated trapped-ion platforms while preserving the coherence necessary for advanced quantum operations. âAchieving this photonic interconnect milestone is a pivotal moment in our roadmap as we move from individual quantum processors to distributed, networked architectures,â said Niccolo de Masi, IonQâs CEO. âScaling quantum computation beyond the limits of a single chip is essential for realizing a future quantum internet. This demonstration proves that our trapped-ion platform is uniquely suited for the high-fidelity networking required to solve the worldâs most complex problems." The successful demonstration of these network qubits underscores the repeatability and reliability of IonQâs hardware as the company transitions toward fault-tolerant, modular systems. This research was, in part, funded by the U.S. Government through an agreement with the Air Force Research Laboratory (AFRL). The project highlights IonQâs ongoing engagement with federal and defense partners to advance national security and scientific research capabilities including its advancement to Stage B of DARPAâs quantum benchmarking initiative; the launch of its IonQ Federal division; the appointment of former Chief of Space Operations for

Chemically Accurate Molecular Simulations Demonstrated on IQM Sirius Hardware

In an experimental study from researchers across India, Singapore, and the USA, IQM’s Sirius 24-qubit superconducting processor was utilized to demonstrate high-accuracy molecular simulations. The research employed Sample-based Quantum Diagonalization (SQD), a noise-resilient paradigm that uses the quantum processor as a “configuration sampler” rather than a direct energy estimator. By identifying high-weight Slater determinants (electron configurations) on the hardware and performing exact diagonalization on a classical computer, the team decoupled the final energy precision from individual quantum gate errors, achieving results within chemical accuracy for several benchmark molecules. The study benchmarked two distinct quantum circuit “blueprints” or ansätze: the Local Unitary Cluster Jastrow (LUCJ) and the Linear-CNOT Unitary Coupled-Cluster (LCNot-UCCSD). The LUCJ ansatz proved highly effective due to its shallow circuit depth, while the LCNot-UCCSD, despite reducing classical pre-computation needs, faced challenges with deeper circuits that impacted data recovery for larger molecules like water (H2O) and ammonia (NH3). This comparative analysis provides a roadmap for selecting the most efficient algorithms for “noisy” near-term quantum hardware. A significant highlight of the paper is the generation of Potential Energy Surfaces (PES). The researchers reported the first experimental generation of a full two-dimensional (2D) PES map for the water molecule on superconducting hardware. By scanning a 32×32 grid of bond lengths and bond angles, they mapped the molecule’s energy landscape with precision matching exact classical full configuration interaction (FCI) results. These surfaces are critical for understanding how molecules vibrate, rotate, and undergo chemical reactions. To address larger, more complex systems, the team integrated SQD with Density Matrix Embedding Theory (DMET). This hybrid strategy allows a large molecule to be broken down into smaller “fragments” that can be computed on the quantum hardware, while the rest of the molecular environment is handled classically. This allowed the researchers to simulate eight ligand-like molecules and the

5 Unrivaled Stocks of the Next 5 Years

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard. Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences. At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000. Do the math. According to Musk, this technology could be worth $250 trillion by 2040. Put another way, that’s roughly equal to: - 175 Teslas - 107 Amazons - 140 Metas - 84 Googles - 65 Microsofts - And 55 Nvidias And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy. It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide. Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential. How could anything be worth that much? The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates. And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors. What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution. In fact, Verge argues this company’s supercheap AI technology should concern rivals. Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves. - Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education,

D-Wave <b>Quantum's</b> Explosive Orders and Energy Pitch Ignite a 54% Surge

D-Wave Quantum's Explosive Orders and Energy Pitch Ignite a 54% Surge 18.04.2026 - 16:13:59 | boerse-global.deA staggering 54% weekly rally in D-Wave Quantum Inc. shares has jolted the market, fueled by a historic influx of orders and a CEO’s compelling argument that quantum computing holds the key to solving artificial intelligence's voracious energy demands. The stock closed Friday at $21.69, propelled by a surge in trading volume that saw 90.2 million shares change hands on Wednesday alone—227% above the three-month average. The core of the rally is a fundamental shift in the company's commercial traction. D-Wave has already secured $32.8 million in bookings since the start of the year, a figure that dwarfs its total revenue for the entire 2025 fiscal year, which stood at $24.6 million. This explosive growth is anchored by two landmark deals: a $20 million system sale to Florida Atlantic University and a separate two-year, $10 million enterprise cloud services contract with a major U.S. corporation. CEO Alan Baratz has been aggressively framing this progress on the global stage. At both the Semafor World Economy Summit and the QED-C Quantum Summit in mid-April, he positioned D-Wave’s technology as a practical, energy-efficient solution already in use by clients like Volkswagen and Lockheed Martin for logistics and scheduling. "Our quantum computers have already solved problems that classical systems simply cannot solve," Baratz told Yahoo Finance, highlighting that a D-Wave system consumes about 10 kilowatts, a fraction of the power required by a classical data center for the same task. This energy-efficiency thesis received a significant tailwind from the broader sector. Nvidia's recent introduction of an open-source model named "Ising," designed specifically for quantum workloads, ignited investor enthusiasm for quantum optimization, D-Wave's specialty. Should investors sell immediately? Or is it worth buying D-Wave Quantum? Financially, the company's fourth-quarter 2025

Army taps civilian hackers to test drone comms in first-of-its-kind exercise

NEW DELHI: Intercepting an adversary’s drone communications can be as valuable as shooting it down but only if the data can be exploited. In a first, the Indian Army opened its drone communication systems to civilian hackers and engineers to test the security of its next-generation communications. Held in Bengaluru earlier this month, the experiment, termed “Crack the Uncrackable”, brought together teams from across the country, including engineers, data scientists and cybersecurity specialists, as part of a broader effort to tap civilian expertise for strengthening defence technologies. Participants were given access to encrypted data from Army drone transmissions, along with a live drone and ground control setup where real-time interception attempts could be made. The challenge had two parts. One involved analysing pre-recorded encrypted data, while the other required teams to attempt live interception of drone communications. Participants were not told what encryption was used and were expected to identify patterns or extract any useful information through analysis alone, mirroring real-world conditions where adversaries attempt to make sense of intercepted data without prior knowledge. Despite sustained efforts using a range of approaches, including data analysis, signal profiling and machine learning techniques, no team could identify the encryption method or extract any meaningful information from the intercepted data. “The output appeared like random data, with no visible patterns or markers to indicate how it was encoded. In effect, while the data could be intercepted, it could not be read or understood,” an Army official explained. He added that the systems are part of a broader push towards “quantum-safe” encryption, meant to remain secure even against future quantum computers, which could challenge existing encryption standards as early as 2030. The exercise also saw teams attempt more advanced approaches, including analysing transmission timing and data volumes and using machine learning (ML) models to

NVIDIA didn't invest in Xanadu, but it made its CEO a billionaire anyway

Christian Weedbrook, the founder and CEO of Toronto-based Xanadu Quantum Technologies, became a billionaire this week without NVIDIA investing a single dollar in his company. His 46.4 million multiple-voting shares were worth approximately $1.5 billion as of midday Friday, after Xanadu’s stock surged nearly fivefold in six trading sessions. The catalyst was not anything Xanadu did. It was NVIDIA announcing a suite of open-source AI models and a new hardware architecture designed to accelerate quantum computing, which sent the entire sector into a rally that made Xanadu, the only publicly traded pure-play photonic quantum computing company, the most dramatic beneficiary. Xanadu went public on 27 March via a SPAC merger with Crane Harbor Acquisition Corp., listing on both the Nasdaq and the TSX. The stock was already up from its IPO price when NVIDIA’s announcements began landing on 14 April. It rose 17% on Friday, 28% on Monday, 29% on Tuesday, and 70% on Wednesday, when the Canadian Investment Regulatory Organization imposed five trading halts in a single session. The stock has gained roughly 194% since listing. What NVIDIA actually did NVIDIA did not buy Xanadu shares, sign a contract with the company, or name it as a partner. What it did was make quantum computing look closer to useful than it has ever looked before, and the market priced that in across every quantum stock simultaneously. On 14 April, NVIDIA launched Ising, a family of open-source AI models designed to solve the two problems that have kept quantum computers from being practical: error correction and calibration. The error correction models are up to 2.5 times faster and three times more accurate than current industry standards. The calibration models reduce quantum processor setup time from days to hours. Both address bottlenecks that have made quantum hardware expensive to operate and

The Lightning Network isn't 'helplessly broken'

The Lightning Network isn’t ‘helplessly broken’ Shell argues the network is fixable and proposes a different framing to the recent quantum debate. A post from Udi Wertheimer a few weeks ago made headlines across crypto media with a stark claim: the Lightning Network is "helplessly broken" in a post-quantum world, and its developers can do nothing about it. The headline traveled fast. For businesses that have built real payment infrastructure on Lightning or are evaluating it, the implications were unsettling. It deserves a measured response. Wertheimer is a respected Bitcoin developer, and his underlying concern is legitimate: quantum computers, if they ever become sufficiently powerful, pose a real long-term challenge to the cryptographic systems on which Bitcoin and Lightning depend. That part is true, and the Bitcoin development community is already working on it seriously. But the framing of Lightning as "helplessly broken" obscures more than it reveals, and businesses making infrastructure decisions deserve a clearer picture. What Wertheimer got right Lightning channels require participants to share public keys with their counterparty when opening a payment channel. In a world where cryptographically relevant quantum computers (CRQCs) exist, an attacker who obtains those public keys could theoretically use Shor's algorithm to derive the corresponding private key, and from there, steal funds. This is a real structural property of how Lightning works. What the headline leaves out The threat is far more specific and far more conditional than "your Lightning balance can be stolen." First, the channels themselves are protected by a hash while they are open. Funding transactions use P2WSH (Pay-to-Witness-Script-Hash), meaning the raw public keys inside the 2-of-2 multisig arrangement are hidden onchain for as long as the channel remains open. Lightning payments are also hash-based, routed through HTLCs (Hashed Time-Lock Contracts), which rely on hash preimage revelation rather than
