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

For years, quantum computers have been framed as the ultimate problem solvers, machines that would eventually crack any task that classical hardware could not touch. Now a new line of research is ...

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 ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems. Imagine a ...

The Defense Advanced Research Projects Agency is looking for companies to build the hardware and software quantum computers need to communicate and work together. Most quantum computers are standalone ...

It remains an open question when a commercial quantum computer will emerge that can outperform classical (non-quantum) machines in speed and energy efficiency while solving real-world combinatorial ...
