New research says today’s quantum computers are far too weak to threaten Bitcoin’s cryptography, leaving the network years to ...

Bitcoin isn't under attack by a quantum computer right now.

Algorand’s state proofs utilize the Falcon signature scheme to provide post-quantum secure attestations of the blockchain state. Privacy coins like Zcash will be prime targets for quantum computers ...

Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now ...

By using controlled microwave noise, researchers created a quantum refrigerator capable of operating as a cooler, heat engine, or amplifier. This approach offers a new way to manage heat directly ...

While it's no replacement for either computer, the new device is a powerful alternative for addressing some very practical ...

Artificial intelligence changed how decisions are made. Quantum computing will decide whether those decisions remain secure.

Scientists have finally figured out how to read ultra-secure Majorana qubits—bringing robust quantum computing a big step closer. “This is a crucial advance,” says Ramón Aguado, a CSIC researcher at ...

If you are to believe the glossy marketing campaigns about ‘quantum computing’, then we are on the cusp of a computing ...

The key point is that most of the potentially exposed bitcoin isn’t sitting in a handful of giant, juicy targets. It’s ...

For decades, the solution to harder problems has been ‘build a bigger computer’— but ...
