Josephson junction microwave modulators for qubit control (1610.07987v2)
Published 25 Oct 2016 in cond-mat.supr-con, cond-mat.mes-hall, and quant-ph
Abstract: We demonstrate Josephson junction based double-balanced mixer and phase shifter circuits operating at 6-10 GHz, and integrate these components to implement both a monolithic amplitude/phase vector modulator and a quadrature mixer. The devices are actuated by flux signals, dissipate no power on chip, exhibit input saturation powers in excess of 1 nW, and provide cryogenic microwave modulation solutions for integrated control of superconducting qubits.
