One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

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

The hope for quantum computers is that the devices will be able to solve complex tasks such as predicting how chemicals react or cracking encrypted text. One of the main reasons that the machines are ...

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 ...

Google has announced that it has developed a 'quantum computer that can solve a computational problem that takes 10,000 years even in the world's fastest supercomputer in 3 minutes and 20 seconds.' ...

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

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 ...

Japanese researchers have helped develop an optical quantum computer that has the potential to drastically reduce the size of the next-generation computer and do even faster calculations. Because a ...
