Physicists Propose a 'Force Field' to Protect Sensitive Quantum Computers From Noise


Physicists Propose a Force Field to Protect Sensitive Quantum Computers From Noise
19 FEBRUARY 2021
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. ....

Researchers create 'beautiful marriage' of quantum enemies

Researchers create ‘beautiful marriage’ of quantum enemies
Cornell scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics.
Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity – in which electrical resistance vanishes completely – and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied.
“This is a beautiful marriage of the two things we know, at the microscale, that give electrons the most startling quantum properties,” said Debdeep Jena, the David E. Burr Professor of Engineering in the School of Electrical and Computer Engineering and Department of Materials Science and Engineering. Jena led the research, published Feb. 19 in Science Advances, with doctoral student Phillip Dang and research associate Guru Khalsa, the paper’s senior authors. ....
