Title: Qubit teleportation between a memory-compatible photonic time-bin qubit and a solid-state quantum network node
(Submitted on 27 Mar 2024)
Abstract: We report on a quantum interface linking a diamond NV center quantum network node and 795nm photonic time-bin qubits compatible with Thulium and Rubidium quantum memories. The interface makes use of two-stage low-noise quantum frequency conversion and waveform shaping to match temporal and spectral photon profiles. Two-photon quantum interference shows high indistinguishability of (89.5 $\pm$ 1.9)% between converted 795nm photons and the native NV center photons. We use the interface to demonstrate quantum teleportation including real-time feedforward from an unbiased set of 795nm photonic qubit input states to the NV center spin qubit, achieving a teleportation fidelity of (75.5 $\pm$ 1.0)%. This proof-of-concept experiment shows the feasibility of interconnecting different quantum network hardware.
