Abstract
Optically accessible spins associated with defects in diamond provide a versatile platform for quantum science and technology. These spins combine multiple key characteristics, including long quantum coherence times, operation up to room temperature, and the capability to create long-range entanglement links through photons. These unique properties have propelled spins in diamond to the forefront of quantum sensing, quantum computation and simulation, and quantum networks.
Highlights
Over the last decade, the development of quantum technologies such as quantum sensors, computers, simulators and networks has become one of the major goals in science and technology
The electrons associated with such defects have a magnetic moment called spin, which is sensitive to magnetic fields because of the Zeeman interaction
Diamond defect spins offer a unique combination of long coherence times, due to the excellent isolation from their environment by the stiff and pure diamond lattice, and the capability to prepare and measure the spin using optics (Fig 1a)
Summary
Accessible spins associated with defects in diamond provide a versatile platform for quantum science and technology. These spins combine multiple key characteristics, including long quantum coherence times, operation up to room temperature, and the capability to create long-range entanglement links through photons. These unique properties have propelled spins in diamond to the forefront of quantum sensing, quantum computation and simulation, and quantum networks. We discuss the application of spins in diamond for quantum sensing, quantum computation & simulation, and quantum networks
