Experimental test of a superconducting digital interface for vortex qubits

Kaplunenko, Vsevolod K.; Ustinov, Alexey V.


We have developed and tested a classical superconducting logic interface to a qubit prototype based on two macroscopically distinct quantum states of a vortex in a long Josephson junction. The initial state preparation as well as the readout of a qubit is demonstrated by using a relatively simple Rapid Single Flux Quantum (RSFQ) circuit. RSFQ logic appears as a very feasible choice for constructing an interface between superconducting qubits and room-temperature electronics.
