• Abstract summary: We show a new approach to relax the impedance matching condition to half impedance matching condition, which is achieved by introducing two-photon drive in the electro-optic transducer. We show the quantum transduction capacity can be enhanced and can be understood in a simple interference picture with the help of Bloch-Messiah decomposition.

• Abstract: Quantum transduction is an essential ingredient in scaling up distributed quantum architecture and is actively pursued based on various physical platforms. However, demonstrating a transducer with positive quantum capacity is still practically challenging. In this work, we discuss a new approach to relax the impedance matching condition to half impedance matching condition, which is achieved by introducing two-photon drive in the electro-optic transducer. We show the quantum transduction capacity can be enhanced and can be understood in a simple interference picture with the help of Bloch-Messiah decomposition. The parameter regimes with positive quantum capacity is identified and compared with and without the drive, indicating that the parametric drive-induced enhancement is really promising in demonstrating quantum state conversion, and is expected to boost the performance of transduction with various physical platforms.

  We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits. We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

• Passive environment-assisted quantum transduction with GKP states [2.5578936059708783]
  Quantum transducers convert quantum signals from one carrier to another through hybrid interfaces of physical systems. For a quantum transducer between two bosonic modes, direct quantum transduction without shared entanglement or classical communication typically requires a conversion efficiency exceeding 0.5. We find that by choosing the ideal Gottesman-Kitaev-Preskill (GKP) states as the initial states of both modes, perfect quantum transduction can be achieved at arbitrarily low conversion efficiencies.
