A paper has been published in Nature Nanotechnology describing ground-breaking results obtained by Quantum e-leaps ETH Zurich team. The paper by Vries et al. describes a gate-controllable Josephson junction made in magic-angle twisted bilayer graphene. In this new type of device the superconducting state can be turned on or off on demand in different nanoscale regions of the device. This allows to explore superconducting phenomena in much greater detail, and it opens up for a completely new regime of ‘programmable’ electronic superconducting devices.
