-Experts warn a 'Quantum Apocalypse' could make everyone's data vulnerable

-Quantum computers may become powerful enough to break all encryptions 

-This will lead to exposure of sensitive information such as banking details

A 'Quantum Apocalypse' could tear open everything from internet banking to government secrets — and experts warn it's just years away.

This fear was thrown into focus earlier this year when an academic paper by Chinese researchers suggested that a quantum computer (a new technology under development by Google and IBM, among others) could break the encryption which keeps us safe online.
