Quantum computers are coming. And when they arrive, they are going to upend the way we protect sensitive data. Unlike classical computers, quantum computers harness quantum mechanical effects — like ...

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

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 ...

Google quantum pioneer says encryption-breaking use cases may arrive sooner than expected, urging crypto industry to prepare now ...

An American physicist and Canadian computer scientist received the A.M. Turing Award on Wednesday for their groundbreaking ...

If I could get into the nitty-gritty of cryptography and quantum computing, I would be off doing that. With that said, this ...

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 ...

Physicist Peter P. Orth (left) and computer scientist Markus Bläser are collaborating on the QIAPO project with industry partners Infineon and BMW, as well as the quantum startup planqc, to explore ...

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 ...

Rice University quantum computing researchers have introduced a novel algorithm with the potential to speed up quantum computing. This algorithm landed the team in the finals for the XPRIZE Quantum ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Qilimanjaro is selling a relatively cheap kit with everything you need for a quantum computer – you just need to be able to ...
