How to use Maxwell’s demon to prepare a quantum bit
Показать описание
New quantum computing feat is a modern twist on a 150-year-old thought experiment
UNSW Sydney research demonstrates a 20x improvement in resetting a quantum bit to its ‘0’ state, using a modern version of the ‘Maxwell’s demon’.
A team of quantum engineers at UNSW Sydney has developed a method to reset a quantum computer – that is, to prepare a quantum bit in the ‘0’ state – with very high confidence, as needed for reliable quantum computations. The method is surprisingly simple: it is related to the old concept of ‘Maxwell’s demon’, an omniscient being that can separate a gas into hot and cold by watching the speed of the individual molecules.
We're the official channel of UNSW Sydney, a brilliantly located university between the coast and the city.
