Physicists propose a 'force field' to protect sensitive quantum computers from noise

C C Offline

INTRO: Creating a quantum computer requires an ability to stroke the edges of reality with the quietest of touches. Too much 'noise' and the delicate state of the system collapses, leaving you with a very expensive paperweight. One way to reduce the risk of this occurring is to build in checks and balances that help to shield the blurred state of reality at the core of quantum computers - and now scientists have proposed a new way to do just that. Theoretical physicists from RWTH Aachen University in Germany have proposed what's known as a 'synthetic magnetic field', which they think could help protect the fragile qubits needed in a quantum computer...
