A tunable Fabry-Pérot quantum Hall interferometer in graphene
Similar to optical waves, electrons can also interfer, but they require high-quality devices with minimal scattering for an experimental observation of this effect. An interferometer based on a single sheet of graphene provides an alternative to the more standard semiconductor devices and may in future enable access to exotic quantum effects, such as anyon braiding.
