Part one explained the physics of quantum computing. This piece explains the target — how bitcoin's encryption works, why a ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

The day when a quantum computer manages to break common encryption, or Q-Day, is fast approaching, and the world is not close ...

A look at the legal aspects and relevant laws regarding a hypothetical theft of bitcoin utilizing quantum computers.

For quantum computing to reach the point where it is fault-tolerant, scalable, and commercially viable, it’s going to be with ...

Foundational to the work on quantum error correction (QEC) are logical qubits, which are created by entangling multiple ...

New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

A new ultra-fast technique allows scientists to track how quickly quantum information disappears. This breakthrough could ...

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...

Most of the crypto industry spent this week processing Google's paper on how quantum computers could break blockchain encryption. One startup is asking a different question — whether quantum hardware ...
