UNSW Announces Increase in Coherence Time of Spin-Orbit Quantum Bit in Silicon; Preserving Quantum Information Longer

By IQT News posted 21 Jul 2020

(ZDNet) A team led by scientists from the University of New South Wales (UNSW) has announced “significantly” increasing the coherence time of a spin-orbit quantum bit (qubit) in silicon, allowing them to preserve quantum information for longer.
The ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T), based out of UNSW, said the results open up a new pathway to make silicon quantum computers more scalable and functional.
“Spin-orbit qubits have been investigated for over a decade as an option to scale up the number of qubits in a quantum computer, as they are easy to manipulate and couple over long distances. However, they have always shown very limited coherence times, far too short for quantum technologies,” a release from CQC2T explained.
