Remote communication between two superconducting qubit modules 2

ORAL

Abstract

We report our experimental progress towards implementing a heralding protocol for the transfer of an arbitrary qubit state between two distant superconducting qubits. We employ sideband interactions induced by parametric flux modulation for the preparation of locally entangled qubit-photon states, as well as for their transfer that generates entanglement between two distant superconducting qubits. As an useful application, we demonstrate how Bell states can be created between the two remote qubits via this technique. Through encoding a qubit state with two flying microwave photons, photon loss error can be heralded by the measurement of the receiving qubit, without the need of using ancillary qubits. This simple and efficient communication protocol provides a promising approach for realizing a scalable quantum network processor using the quantum computation modules as building blocks.
