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

Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the ...

Google published a paper on March 31 that states that Bitcoin's cryptography could be impacted by quantum computing sooner ...

The clock is ticking on cryptocurrency.

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

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

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 ...

Caltech researchers cut quantum computing qubit estimates by 100x, putting encryption-breaking quantum computers theoretically within reach this decade.

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...

The research shows quantum computers may break bitcoin and ether wallet encryption with far fewer qubits than previously ...

The world of quantum computing has its fair share of believers and sceptics. While some call it the technology of the future that could see many modern technologies like cryptography rendered useless, ...
