A quantum computer algorithm that is used to find the prime factors in an encryption key. Created by applied mathematician Peter Shor in the mid-1990s, Shor's algorithm may be used to break the codes ...

Experts warn quantum computers could someday forge Bitcoin’s digital signatures, allowing unauthorized transactions.

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this. Despite ...

A new report by Capgemini warns that quantum computing may break the widely used public-key cryptographic systems within the next decade — threatening everything from online banking to blockchain ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...
