Making quantum computing more resilient

Quantum computing systems could be made more stable and efficient thanks to a discovery about the way some atomic particles behave. The University of Leeds' Theoretical Physics Research Group has come up with a new way of making quantum particles defy the rules of statistical physics by utilising a special quantum computing device. Generally, a bunch of quantum particles tend to spread out over time, and do not regroup. This process, known as thermalisation, is believed to be the inevitable fate of many-body quantum systems, which contain many interacting particles. The research group, led by Dr Zlatko Papic, Associate Professor in Theoretical Physics in Leeds' School of Physics and Astronomy , previously theorised that in some quantum many-body systems, the particles can regroup, acting like droplets of perfume gathering back together after being sprayed from a bottle. These systems are called quantum many-body scars. Experimental physics.
