Abstract
A system for optical transduction of quantum information includes a qubit chip including a plurality of data qubits configured to operate at microwave frequencies, and a transduction chip spaced apart from the qubit chip, the transduction chip including a microwave-to-optical frequency transducer. The system includes an interposer coupled to the qubit chip and the transduction chip, the interposer including a dielectric material including a plurality of superconducting microwave waveguides formed therein. The plurality of superconducting microwave waveguides is configured to transmit quantum information from the plurality of data qubits to the microwave-to-optical frequency transducer on the transduction chip, and the microwave-to-optical frequency transducer is configured to transduce the quantum information from the microwave frequencies to optical frequencies.
