#### Single-photon heralded two-qubit unitary gates for pairs of nitrogen-vacancy centers in diamond

C Liu, MVG Dutt, D Pekker

The implementation of a high-fidelity two-qubit quantum logic gate remains an outstanding challenge for isolated solid-state qubits such as nitrogen-vacancy (NV) centers in diamond. In this work, we show that by driving pairs of NV centers to undergo photon scattering processes that flip their qubit states simultaneously, we can achieve a unitary two-qubit gate conditioned upon a single photon-detection event.
