Approaching the ultrastrong coupling regime between an Andreev level and a microwave resonator
O. O. Shvetsov, A. Khola, V. Buccheri +5
Josephson junctions formed in semiconductor nanowires host Andreev bound states and serve as a physical platform to realize Andreev qubits tuned by electrostatic gating. With the A…
