With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to ...

The new approach to reduce quantum errors applies gauge theory to track global quantum activity, such as across a "quantum hard drive," without collapsing local qubit states, according to the study ...

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

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough ...

Scientists at California Institute of Technology and startup Oratomic have developed a method to ...

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

Two analyses suggest that quantum computers could crack ubiquitous security keys and cryptocurrencies before the decade is ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

A method reduces the number of qubits needed for quantum computers, making practical machines possible sooner and affecting ...

One huge issue Rigetti is facing right now is that as the number of qubits in the system increases, its accuracy quickly ...
