Hexagonal boron nitride (h-BN) hosts pure single-photon emitters that have shown evidence of optically detected electronic spin dynamics. However, the electrical and chemical structures these addressable spins are unknown, nature their spin-optical interactions remains mysterious. Here, we use time-domain optical microwave experiments to characterize a single emitter in h-BN exhibiting room temperature magnetic resonance. Using dynamical simulations, constrain quantify transition rates...
Abstract As quantum networks expand and are deployed outside research laboratories, a need arises to design integrate compact control electronics for each memory node. It is essential understand the performance requirements such systems, especially concerning tolerable levels of noise, since these specifications dramatically affect system's complexity cost. Here, using an approach that can be easily generalized across quantum‐hardware platforms, case study based on nitrogen‐vacancy (NV)...
Defect-based quantum emitters in solid-state materials offer a promising platform for communication and sensing. Confocal fluorescence microscopy techniques have revealed multitude of host materials. The ability to quickly accurately survey emitter ensembles is important characterizing these new systems. In some materials, however, optical properties vary widely among emitters, even within the same sample. cases, traditional ensemble measurements are confounded by heterogeneity, whereas...
Solid-state electron spins are key building blocks for emerging applications in quantum information science, including computers, communication links, and sensors. These solid-state mainly controlled using complex microwave pulse sequences, which typically generated benchtop electrical instruments. Integration of the required electronics will enable realization a scalable low-power compact optically addressable system. Here, we report an integrated reconfigurable control system, is used to...
Nuclear quadrupolar resonance (NQR) spectroscopy reveals chemical bonding patterns in materials and molecules through the unique coupling between nuclear spins local fields. However, traditional NQR techniques require macroscopic ensembles of nuclei to yield a detectable signal, which precludes study individual obscures molecule-to-molecule variations due perturbations or deformations. Optically active electronic spin qubits, such as nitrogen-vacancy (NV) center diamond, facilitate detection...
