Quantum entanglement explained, from Einstein's skepticism to practical applications in quantum computing on a 20-nanometre scale.

We all face situations where we need to transfer large or important files between two computers, but don't have a USB stick or hard disk at hand to rescue. Cloud storage solutions can be convenient ...

A ‘quantum telephone’ connecting atomic nuclei could make practical quantum computers easier to build and use.

While quantum computers are already being used for research in chemistry, material science, and data security, most are still too small to be useful for large-scale applications. A study led by ...
