Opening a new window into quantum physics

A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement.

Quantum physics secures new cryptography scheme

The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the internet and in everyday life, for example at a bank's ATM.

Quantum physics could make secure, single-use computer memories possible

Computer security systems may one day get a boost from quantum physics, as a result of recent research from the National Institute of Standards and Technology (NIST). Computer scientist Yi-Kai Liu has devised away to make a security device that has proved notoriously difficult to build—a "one-shot" memory unit, whose contents can be read only a single time.

Adding to Einstein’s quantum world

Almost 80 years after Einstein referred to quantum entanglement as ‘spooky action at a distance’, scientists have found a new form of entanglement involving three particles instead of just two.

And Chalmers University said 'let there be light'

Scientists at Chalmers University of Technology have succeeded in creating light from vacuum.
