On-chip Microwave-to-Optical Transducer Based on Rare-Earth Ions

Tian Xie, Jake Rochman, John G. Bartholomew +2 more

Microwave-to-optical transduction is essential for connecting superconducting platforms with optical quantum networks. We demonstrate coherent transduction in both continuous-wave and pulsed mode using rare-earth ions with an integrated superconducting microwave resonator and nanophotonic optical resonator.

On-chip coherent microwave-to-optical transduction mediated by ytterbium in YVO4

John G. Bartholomew, Jake Rochman, Tian Xie +5 more

Abstract Optical networks that distribute entanglement among various quantum systems will form a powerful framework for quantum science but are yet to interface with leading quantum hardware such as superconducting qubits. Consequently, these systems remain isolated because microwave links at room temperature are noisy and lossy. Building long distance connectivity requires interfaces that map quantum information between microwave and optical fields. While preliminary microwave-to-optical transducers have been realized, developing efficient, low-noise devices that match superconducting qubit frequencies (gigahertz) and bandwidths (10 kilohertz – 1 megahertz) remains a challenge. Here we demonstrate a proof-of-concept on-chip transducer using trivalent ytterbium-171 ions in yttrium orthovanadate coupled to a nanophotonic waveguide and a microwave transmission line. The device′s miniaturization, material, and zero-magnetic-field operation are important advances for rare-earth ion magneto-optical devices. Further integration with high quality factor microwave and optical resonators will enable efficient transduction and create opportunities toward multi-platform quantum networks.Abstract Optical networks that distribute entanglement among various quantum systems will form a powerful framework for quantum science but are yet to interface with leading quantum hardware such as superconducting qubits.

Quantum nanophotonic devices based on rare-earth ions (Conference Presentation)

Andrei Faraon

In this talk I give an overview of our recent work on quantum nano-photonic devices based on rare-earth ions. The rare-earth ions exhibit excellent optical and spin coherence properties when embedded in nano-photonic devices. This enables on-chip optical quantum memories, single rare-earth-ion optically addressable quantum bits, and devices for quantum transduction. I will focus on our recent results based on ytterbium 171 in yttrium orthovanadate.
