The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous ...

A group of Chinese researchers has claimed to be able to break a widely used encryption scheme with a quantum computer that already exists, creating a possible boon for surveillance and a crisis for ...

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 ...

Hardware faults are leaking hundreds of supposedly unbreakable encryption keys on to the internet, researchers have found – and spy agencies may be exploiting the loophole to read secret messages. RSA ...
