A July 15 report by global consulting firm Capgemini warns that public-key cryptographic systems, including RSA and elliptic ...

Now quantum software company Cambridge Quantum (CQ) says it has developed a "quantum-safe" method that could future-proof any blockchain by making the system invulnerable to quantum attacks ...

Quantum-proofing blockchain is crucial for both the American public and private sector. Yet the U.S. currently lags behind Canada, Australia, South Korea, and Switzerland, ...

Bitcoin relies on elliptic curve cryptography (ECC) to secure wallet addresses and validate ownership. But ECC, like RSA, is ...

This quantum blockchain has another advantage: the earlier blocks are completely tamper-proof. “The attacker cannot even attempt to access the previous photons since they no longer exist,” say ...

Quantum computing has been on the tech radar for some time now, but it has also been lurking in the background of the blockchain ecosystem for very different reasons.

A new — and theoretical — system for blockchain-based data storage could ensure that hackers will not be able to crack cryptocurrencies once the quantum era starts. The idea, proposed by ...

D-Wave Quantum Inc., a leader in quantum computing systems, software, and services, today announced that it has published a new research paper introducing a novel blockchain architecture that uses ...

Blockchain is meant to be secure—but a new paper from quantum computing scientists warns that quickly advancing quantum technology poses a vulnerability for the much-hyped blockchain. Blockchain ...

Quantum computing may eventually outperform classical proof-of-work mining, destabilizing blockchain security. Estimates vary, but experts predict this risk will materialize within 10-20 years.

Blockchain companies: IBM, Google and a number of other technology giants are the current movers in developing quantum computing. It is likely that they will not enable users of quantum computing ...

“Previous blockchains that worked with quantum operations were presented, but the blockchain itself was never quantum,” said Rajan, as reported by IEEE Spectrum. “We are presenting the first fully ...
