Multi-qubit devices based on nuclear spins in diamond

Abstract

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.
