Quantum state transfer between a frequency-encoded photonic qubit and a quantum-dot spin in a nanophotonic waveguide

We propose a deterministic yet fully passive scheme to transfer the quantum state from frequency-encoded photon spin of dot mediated by nanophotonic waveguide. assess quality studying effects all relevant experimental imperfections on state-transfer fidelity. show that fidelity exceeding $95%$ is achievable for experimentally realistic parameters. Our work sets stage solid-state networks tailored photonic qubits.
