Abstract: Large-scale fault-tolerant superconducting quantum computation needs rapid quantum communication to network qubits fabricated on different chips and long-range couplers to implement efficient quantum error-correction codes. Quantum channels used for these purposes are best modeled by multimode resonators, which lie between single-mode cavities and waveguides with a continuum of modes. In this Letter, we propose a formalism for quantum state transfer using coupling strengths comparable to the channel's free spectral range ($g\sim\Delta_{\text{fsr}}$). Our scheme merges features of both the STIRAP-based methods for single-model cavities and the pitch-and-catch protocol for long waveguides, integrating their advantage of low loss and high speed.

Multiplexed quantum state transfer in waveguides [0.0]
A quantum network serves as a testbed to show how to maximize the storage and manipulation of quantum information in QED setups. We analyze two approaches using wavepacket engineering and quantum state transfer protocols. We show that state-of-the-art experiments can employ dozens of multiplexed photons with global fidelities fulfilling the requirements imposed by fault-tolerant quantum computing.
