February 25, 2021EPFL Using the IBM Q computer, physicists at EPFL have verified for the first time the tight relationship between quantum entanglement and wave-particle duality, showing that the former controls the latter in a quantum system. “It is possible to do experiments in fundamental physics on the remotely accessible IBM Q quantum computer,” says Marc-André Dupertuis, a physicist at EPFL’s School of Basic Sciences. Working with Nicolas Schwaller, a Master student in Physics at EPFL, and Clément Javerzac-Galy, co-CEO of photonics company Miraex, the three scientists carried out their work by studying a system made of two separate quantum elements, represented in the IBM Q as superconducting quantum bits.
