Menno Veldhorst and Giordano Scappucci receive physics projectruimte

Menno Veldhorst and Giordano Scappucci receive 600keuro from NWO to study macroscopic entanglement between spins in germanium. In this combined materials science and physics project, germanium will be explored as quantum material to integrate superconductivity and quantum dots. Novel hybrid systems will be created with the goal to demonstrate entanglement between two spins over a macroscopic distance on a single chip. A superconducting resonator will be constructed that can be directly coupled to hole spins in germanium, maximizing coupling and minimizing loss. Spin-orbit coupling will act as driving force for fast electrical qubit rotations, while creation of entanglement between two spins will be mediated by microwave resonator photons.
