Unraveling an exotic electronic state for error-free quantum computation

Abstract

A recently proposed approach could lead to a totally new architecture for quantum computation with an exceedingly low error rate by exploiting quasiparticles that behave differently from fundamental particles in nature. Highly sensitive nuclear magnetic resonance measurements have unraveled an electronic state in a semiconductor device that is expected to host such exotic quasiparticles. The experimental results support the theory predicting that this state will have properties suitable for errorfree quantum computation.
