Optically active spins in solid state materials are an important candidate for quantum communication and distributed quantum computation over a network. To increase the size of quantum networks, long-lived quantum memories in a network node and high-fidelity control of qubits in the network nodes are desired.
We discuss how isotopically engineered diamond can offer long-lived nuclear spin qubits that are robust to the optical link operation of the NV center. Furthermore, we use gate set tomography to report single-qubit and two-qubit gate fidelities exceeding 99.9% for the electron and nitrogen-nuclear spin of an NV center diamond.
Nuclear spins in diamond are promising for their use as qubits in quantum computers and quantum networks, and for simulating many-body physics phenomena. Building on recent results [1,2], we combine precise knowledge of the nuclear spin environment with dynamic nuclear polarization techniques and selective readout protocols to extend control over more nuclear spin qubits within a large interacting cluster. These techniques open the door to the quantum simulation of complex many-body physics phenomena using nuclear spins in diamond. [1] – M. H. Abobeih et al. Nature, 576, 411–415 (2019) [2] – C. E.
