Quantum transfer at the push of a button

In new quantum information technologies, fragile quantum states have to be transferred between distant quantum bits. Researchers at ETH have now realized such a quantum transmission between two solid-state qubits at the push ...

Bitcoin more vulnerable to attack than expected

Calculations by University of Twente researchers show that Bitcoin is more vulnerable to attack than people had always assumed. If some Bitcoin users were to form a group that controls 20 percent of the currency's computing ...

Controlled coupling of light and matter

Researchers from Würzburg and London have succeeded in controlling the coupling of light and matter at room temperature. They have published their results in Science Advances.

Retrospective test for quantum computers can build trust

Tech companies are racing to make commercial quantum computers. A new scheme from researchers in Singapore and Japan could help customers establish trust in buying time on such machines—and protect companies from dishonest ...
