Superconductors exhibit macroscopic quantum effects. Superconductor/semiconductor heterostructures of high crystalline perfection offer a playground for a new generation of devices for quantum computation. Our group investigates such heterostructures to solve the key hurdles towards realistic quantum computing devices. These heterostructures offer the potential to identify and eliminate sources of decoherence and errors holding back the potential of quantum computation.
