Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.

Peter Shor didn’t set out to break the internet. But an algorithm he developed in the mid-1990s threatened to do just that. In a landmark paper, Shor showed how a hypothetical computer that exploited ...

Current data encryption techniques may fend off the threat of quantum computing for some time to come, security experts say. In recent years the computational potential of qubits has led many to ...
