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