The quantum layer will will not be exhausted by one hardware modality, one algorithmic framework or one vendor’s roadmap.

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 ...

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies ...

Most simplifies the complex process of quantum computing as "it can be 0 and 1 at the same time." That is not an explanation ...

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 ...

Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...

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

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

"I genuinely believe that quantum computing talent should be used for good," says Dr Carmen Palacios-Berraquero. The tech ...
