<b>Quantum Computers</b> Now Generate Diverse States, Sidestepping A Major Simulation Hurdle

A new quantum-classical framework for generating ensembles of quantum states enables advancements in quantum simulation, chemistry, and machine learning. Quoc Hoan Tran of Fujitsu Research and colleagues prove that latent-conditioned parameterised quantum circuits (LPQCs) universally approximate probability measures over density operators, extending classical approximation theorems to quantum distributions. The method alleviates the barren plateau problem and achieves competitive performance against both quantum and classical baselines on tasks involving complex ensembles, such as molecular structures, while sharply reducing output dimensionality. By integrating classical neural networks with quantum circuits, LPQCs present a vital pathway towards tractable quantum generative modelling Latent-conditioned circuits enhance quantum state ensemble generation and overcome computational challenges Gate fidelity increased five-fold when generating quantum state ensembles, exceeding previous quantum generative baselines and remaining competitive with classical methods at sharply lower dimensionality. Previously, creating diverse collections of quantum states for complex simulations was computationally prohibitive, hindering progress in materials science and drug discovery. Introducing latent-conditioned parameterised quantum circuits (LPQCs), a hybrid quantum-classical framework, now provides a tractable route to quantum generative modelling, effectively extending classical approximation theorems to quantum distributions. The significance of this lies in the ability to move beyond preparing individual quantum states, a process that scales exponentially with system size, towards generating probability distributions overstates, offering a more efficient approach for representing complex quantum systems. The LPQC framework employs classical neural networks to map latent variables to quantum circuit parameters, enabling efficient generation of varied quantum states and alleviating the barren plateau problem often encountered in quantum machine learning. The barren plateau refers to the phenomenon where the gradients of the cost function vanish exponentially with the number of qubits, hindering the training of parameterised quantum circuits. By introducing a latent space and leveraging the representational power of neural networks, LPQCs effectively navigate this challenging landscape. Researchers

Is Rigetti <b>Computing</b> Stock Going to $50? | The Motley Fool

The stock market is on a tear. Driven by renewed enthusiasm for artificial intelligence (AI), the S&P 500 index is up 6.3% over the last month, while the tech-heavy Nasdaq Composite is up a whopping 9.4%. The run, along with a major announcement from the U.S. Commerce Department, has kicked off a rally in quantum computing stocks. As investors look for the "next AI," they're snapping up shares of companies like IonQ, D-Wave, and, of course, Rigetti Computing (RGTI +0.35%). With the recent launch of its most powerful quantum system to date, many investors believe that Rigetti is one of the most promising quantum pure-plays around. But what about the stock? After jumping more than 50% in a month, is it still a buy? Could shares of Rigetti reach $50? NASDAQ: RGTI Key Data Points Why Rigetti is turning heads in the quantum computing race Rigetti builds superconducting quantum computers, using the same basic approach as Alphabet's Google and IBM. This gives the company's systems a few advantages: speed and scale. Rigetti just launched its most powerful computer to date, the 108-qubit Cepheus-1-108Q. , Beyond the tech itself, the company designs and builds everything in-house, from the quantum chips to the software that runs on them. If its approach delivers, Rigetti would own the entire vertical, giving it a major leg up. As for financials, revenue nearly tripled year over year last quarter, and the company is sitting on more than $400 million in cash, double what it held a year ago. And of course, there is the recent news: The U.S. government will provide $100 million to Rigetti as part of a larger $2 billion quantum investment package. That's a pretty big deal. The risks hiding behind Rigetti's explosive stock rally Revenue nearly tripled last quarter, rising from $1.5

<b>Quantum</b> Circuits Become More Reliable With Improved Error Correction Methods

Researchers Tao Wang and Yun Shang at Chinese Academy of Sciences, have developed a new error mitigation technique to improve the reliability of calculations performed on contemporary quantum computers. Their work introduces a hybrid Gaussian-exponential extrapolation scheme specifically tailored for quantum circuits exhibiting periodic structure, a common characteristic of many quantum algorithms. By modelling noise amplification using a log-normal distribution and incorporating Gaussian variance corrections, the method requires minimal prior noise characterisation and demonstrably reduces bias in calculations across a range of circuit types, including Trotterized Ising dynamics, random circuits, and Grover search. This advancement represents a key step towards obtaining more accurate results from near-term quantum hardware, which is currently limited by the inherent fragility of quantum states and susceptibility to environmental disturbances. Log-normal noise modelling diminishes bias in deep periodic quantum circuits Up to 30% bias reduction in calculations was achieved through this new method, compared to previous extrapolation variants. Existing error mitigation techniques often struggle to maintain accuracy with increasingly complex and deep circuits. These circuits involve many quantum operations, previously rendering accurate results unattainable without substantial qubit overhead, which increases the resources required for computation. Dr. Patrick Draper and Dr. Pranav Patel conceived this new technique for quantum circuits with periodic structure, circuits constructed from repeating blocks of operations. The core innovation lies in modelling noise amplification as a log-normal distribution, a statistically robust approach grounded in the observation that errors tend to accumulate multiplicatively rather than additively. This multiplicative accumulation leads to a distribution of errors that closely resembles a log-normal distribution, allowing for more accurate extrapolation to the zero-noise limit. The hybrid model accurately characterises noise behaviour without requiring prior knowledge of the specific noise affecting the quantum computer, significantly simplifying implementation and broadening its applicability to diverse hardware platforms. This is a crucial

Clarkson researchers advancing use of AI, computational physics | Education | nny360.com

POTSDAM — Researchers at Clarkson University are advancing the use of artificial intelligence and computational physics to accelerate discovery of next-generation materials for quantum technologies, optoelectronics, and renewable energy applications. Associate Professor of Physics Dhara Trivedi recently worked with scientists at Los Alamos National Laboratory on a research project that combined machine learning, high-throughput computational modeling, and quantum-scale simulations to accelerate the discovery of advanced materials with specialized electronic and quantum properties. The team studied two-dimensional perovskites, a group of materials that could improve technologies such as solar panels, sensors, lasers and next-generation computers. The research was published in npj Computational Materials, a journal in the Nature Portfolio. Finding useful materials has traditionally taken years of testing in laboratories. By using artificial intelligence, researchers can now predict which materials are most promising before building them. “Artificial intelligence helps us narrow down the best possibilities much faster,” Trivedi said. “That means scientists can spend more time developing technologies and less time searching for materials that may not work.” The researchers created a database containing more than 2,000 possible material combinations and trained machine learning models to predict important electronic properties. The materials identified in this work could enable advances in renewable energy, quantum information science, and next-generation optoelectronic technologies. Potential applications include more efficient solar cells, low-power electronic devices, quantum computing and communication systems, as well as photodetectors, LEDs, fiber-optic technologies, and advanced sensing platforms. The project also highlights how artificial intelligence and physics-based simulation can work together to accelerate discovery of materials for emerging technologies. . The collaboration between Clarkson University and Los Alamos National Laboratory also demonstrates how universities and national research labs can work together to solve complex scientific challenges and develop technologies with real-world impact. “This work shows how physics, computing and AI can come together to

Demonstrating real-time and low-latency <b>quantum</b> error correction with superconducting qubits

Abstract Quantum error correction will be essential for quantum computers to realise their full potential. As quantum computers advance towards demonstrating a universal fault-tolerant logical gate set, implementing scalable and low-latency real-time decoding will be crucial to avoid an exponential slowdown and maintain a fast logical clock rate. Here, we demonstrate low-latency feedback with a scalable FPGA decoder integrated into the control system of a superconducting quantum processor. We perform an 8-qubit stability experiment with up to 25 decoding rounds and a sub-microsecond mean decoding time per round, providing strong evidence that the backlog problem will be avoided when the decoder is operated as a streaming decoder on a superconducting hardware with the strictest speed requirements. We observe logical error suppression as the number of decoding rounds is increased. We also implement and time a fast-feedback experiment demonstrating a decoding response time of 9.6 μs for a total of 9 measurement rounds.

Agrees We Need A “Right To A Digital-Free Life”

I am 100% in agreement with Randy’s column on page 3 of the April 24 issue of Webster-Kirkwood Times. We need a “Right To A Digital-Free Life” law. I am trying to work myself in that direction, but it is hard and looks to be getting harder. Federal government wants to stop taking paper checks. Filing tax returns by paper is a real hassle now. With Artificial Intelligence and Quantum computers coming, privacy is going to be impossible unless we get offline and do not use computers. Privacy is pretty much gone already. Representative Wagner requires email addresses to take constituent surveys. Huh. Why should I have to enter an email address to do a survey? I just wish more people would wake up to what is happening. Perhaps they will wake up when it’s too late? John Dickey Brentwood

Thematic AI Funds Are Booming. Is <b>Quantum Computing</b> Next?

Thematic AI Funds Are Booming. Is Quantum Computing Next? Quantum computers, which could handle massive calculations faster than current systems, are expected to make a big impact. Sign up for exclusive news and analysis of the rapidly evolving ETF landscape. They might sound like technology out of “Back to the Future,” but quantum computers are no flux capacitors. The US Department of Commerce announced $2 billion in grants to nine quantum computing companies earlier this month, making the federal government a stakeholder in the sector’s commercial success. The move is similar to 2022’s CHIPS Act, which provided funding for the manufacture of semiconductors, a major current growth area in the world of AI-focused and new leveraged ETFs. But quantum computers may hold even more potential, since they could dramatically push forward the fields of AI, finance, healthcare and cybersecurity. It’s an investing theme that could help provide growth opportunities in client portfolios. “We talk a lot about intelligence, whether AI is adding value and productivity,” said Chris Gannatti, global head of research at WisdomTree, which runs a quantum computing ETF. “Quantum computing is a natural extension [of] that.” Quantum Leap For the non-computer scientists among us, a quantum computer is, very basically, a machine that uses quantum physics to solve complex problems that current supercomputers either can’t solve or would take several million years to solve. Beyond the possibilities of quantum computing and the latest federal funding, however, there are also myriad IPOs that might enable more investment. Last week, the quantum computing firm Quantinuum filed for an IPO targeting a valuation of up to $12.7 billion. “People are hungry for new tech-oriented IPOs, and what’s great is instead of just having exposure to one or two public companies, now you’re able to have a more broadly diversified array,” Gannatti
