- Abstract: Integrated quantum photonics devices in diamond have tremendous potential for
many quantum applications, including long-distance quantum communication,
quantum information processing, and quantum sensing. These devices benefit from
diamond's combination of exceptional thermal, optical, and mechanical
properties. Its wide electronic bandgap makes diamond an ideal host for a
variety of optical active spin qubits that are key building blocks for quantum
technologies. In landmark experiments, diamond spin qubits have enabled
demonstrations of remote entanglement, memory-enhanced quantum communication,
and multi-qubit spin registers with fault-tolerant quantum error correction,
leading to the realization of multinode quantum networks. These advancements
put diamond at the forefront of solid-state material platforms for quantum
information processing. Recent developments in diamond nanofabrication
techniques provide a promising route to further scaling of these landmark
experiments towards real-life quantum technologies. In this paper, we focus on
the recent progress in creating integrated diamond quantum photonic devices,
with particular emphasis on spin-photon interfaces, cavity optomechanical
devices, and spin-phonon transduction. Finally, we discuss prospects and
remaining challenges for the use of diamond in scalable quantum technologies.
