Superconducting Qubit Optical Transducer (SQOT)

Abstract

The SQOT (Superconducting Qubit Optical Transducer) project proposes to build a novel electro-optic system which can exchange quantum information between optical qubits at telecom frequencies and superconducting qubits. A direct quantum information transfer between optical qubits and superconducting qubits has not yet been demonstrated. Our scheme is to use high-Q (quality factor) three-dimensional (3D) superconducting qubits fabricated on a nonlinear electro-optic material that forms a high-Q whispering gallery optical cavity. The high quality factors will be essential to achieve coherent quantum behavior, in contract to similar systems in the classical regime. The initial one year effort proposed here will explore the cryogenic behavior of the nonlinear material and optical components necessary to build SQOT for our direct coupling scheme; and measure the coherent coupling coefficient between optical and superconducting qubits with SQOT, which we expect g tilde 10kHz and in the fully quantum coherent regime.
