Watch a movie backwards and you’ll likely get confused – but a quantum computer wouldn’t. That’s the conclusion of researcher Mile Gu at the Centre for Quantum Technologies (CQT) at the National University of Singapore and Nanyang Technological University and collaborators. In research published 18 July in Physical Review X, the international team show that a…
Want More Efficient Simulators? Store Time in a Quantum Superposition
Computer models of systems such as a city’s traffic flow or neural firing in the brain tends to use up a lot of memory. But a new approach with quantum simulators could significantly cut that memory use by taking a quantum approach to time. The only cost is a diminished record of the past. The…
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. “Having quantum cryptography to…
