European financial authorities warned that an advanced quantum computer could undermine cryptography used to secure blockchains, saying the threat could emerge before the technology has a viable commercial application.
An advanced quantum computer “could undermine some cryptography systems widely used to secure communications, transactions, databases and blockchains,” according to the report..
The Satoshi-era bitcoin held in older, legacy addresses or reused addresses could face greater risk if quantum computing advances.
A sufficiently powerful quantum computer could use it to derive the private key and take control of the coins.
The European Union (EU) warning does not say that a quantum computer capable of breaking bitcoin’s cryptography exists today.

That work now has a deadline: Ethereum’s developers want the network’s core systems to resist future quantum attacks by the end of 2029.
Alongside post-quantum security are faster finality, privacy, management of Ethereum’s growing state and zero-knowledge Ethereum Virtual Machines.
The 2029 date is a development target, not a warning that Ethereum’s security has failed.
Campus projects can acquire long-term security responsibilities sooner than their developers expect.
The quantum-security program looks much further ahead, toward whether an application written during college can still work after its original developers have graduated.

EPB knows most businesses don't have a clear idea of how quantum technology could be useful to them.
That's why the Chattanooga utility is hosting its inaugural "Quantum in Business" conference.
The conference agenda includes discussions with titles like "Why This Is a Business Conversation, Not a Physics One" and "How Quantum Moves from Campus to Company."
The conference will bring attendees close to the EPB Quantum Center, the first facility to combine commercial quantum computing and networking in one place, EPB officials said.
The utility announced the Quantum in Business conference in June.

Quantum computing has always struggled to achieve the necessary division of labor between processing and memory.
The researchers say this could fit much more quantum information into a smaller space than electromagnetic memory, while keeping the information stable.
Instead of storing the quantum state as light, they used sound.
phonons, to hold quantum information.
If those efforts pan out, the result could be hardware-efficient quantum random-access memory that eliminates the need for bulky electromagnetic components.

Shares of IonQ are jumping on Wednesday after the company shared a technological breakthrough in quantum computing.
IonQ noted in a statement that quantum error correction is "essential for building practical, fault-tolerant quantum computers because physical qubits are inherently sensitive to environmental noise."
"That creates a processing bottleneck that forces the quantum computer to pause and wait.
Public keys are often revealed once a wallet is used in a transaction.
Bitcoin is seen as especially exposed because its 17-year transaction history has left many public keys visible on-chain.

The center sits within the University of Maryland's Discovery District near Washington, D.C., and is built around Microsoft 's Majorana 2 chip.
Rather than the remote access DARPA previously relied on to reach Microsoft hardware in Redmond, Washington, and in Europe, the agency will now have its own on-site workspace at the facility where its personnel can physically install hardware and execute their own startup procedures, according to Reuters.
Microsoft unveiled the Majorana 2 chip earlier this year, describing it as 1,000 times more reliable than its predecessor.
Qubit lifetimes on the chip reach a mean of 20 seconds, compared with under 12 milliseconds on the previous version.
Microsoft 's quantum program has faced scrutiny from some physicists who say the company has not released enough data to verify its claims, and DARPA scientists have been embedded in the company's quantum work on a weekly basis with full access to its data.

State officials, University of Maryland leaders and quantum research representatives celebrated the opening of the Microsoft Quantum Research Center in the university’s Discovery District Tuesday.
Charlie Tahan, a Microsoft quantum partner, touted the university’s emphasis on quantum research and its proximity to Washington, D.C., as reasons the center is located in College Park.
The lab was announced at last September’s Quantum World Congress with the project being greenlit a day before the event, Tahan said.
The university also expanded faculty and student access to quantum computing machines in an agreement between its National Quantum Laboratory and IBM quantum processing units.
Tuesday’s event also served as an opening for the Quantum World Congress, hosted by the university, later this week.

Against this backdrop, let's consider which of the following pure-play leaders makes the better quantum buy today: IonQ (IONQ +4.12%) or Rigetti Computing (RGTI -1.63%).
The case for IonQ Quantum computing doesn't rely on one method alone.
The case for Rigetti Rigetti, another pure-play quantum giant, uses a different technique than IonQ.
IonQ and Rigetti both offer compelling technology, and each has advanced in two areas key to the success of quantum computing: IonQ is delivering on accuracy, and Rigetti is crushing it when it comes to speed.
And that's why I think IonQ makes the better quantum computing buy right now.

Testing Quantum Entanglement at Extreme Energies What remained less clear was whether entanglement could survive under far more extreme conditions, including the violent, high-energy particle collisions produced at CERN.
The Z bosons examined in the experiment came from the decay of a Higgs boson, the particle discovered at the LHC in 2012.
A Higgs boson can briefly decay into two Z bosons, which then decay into pairs of electrons or muons.
That allowed the team to determine whether the two Z bosons displayed the correlations expected from quantum entanglement.
The result represents one of the highest energy confirmations of quantum entanglement ever achieved.

The Numbers Behind Bitcoin’s Quantum Exposure Problem Bitcoin’s public-key cryptography relies on the elliptic curve digital signature algorithm, or ECDSA, over the secp256k1 curve.
Every time a bitcoin address is used more than once, the public key that gets revealed on the first outgoing transaction stays visible on the blockchain forever after.
That’s a meaningfully different posture than five years ago, when quantum risk barely appeared in custody risk questionnaires at all.
Competitive Comparison: How Other Chains Are Handling Post-Quantum Risk Bitcoin isn’t the only network with this problem, and comparing approaches is useful context.
Yes, mostly by avoiding address reuse, which is responsible for roughly 72% of currently exposed BTC.

They discuss how quantum networking uses shared entanglement to interconnect quantum processors, enabling modular scale-out clusters and quantum-safe connectivity between data centers.
And then once you have access to that, you can build clusters of quantum computers — in our case that can be either homogeneous or heterogeneous, between quantum computers based on a variety of technologies.
Tom: So from the physical perspective, the idea is that you have two quantum devices — let’s say two quantum computers.
Tom: Quantum networking goes much further than quantum memory.
That’s why quantum memories are so central to quantum networking — but you need to build more than memories to build a quantum network.
