Solid-State Quantum Emitters, Sensors, and Photonic Networks
This community develops solid-state materials that generate, store, and detect single photons, and uses atomic-scale defects in crystals to measure magnetic fields and temperature.
The work centers on engineering quantum emitters and spin defects in wide-bandgap materials, specifically silicon carbide, hexagonal boron nitride, and diamond. Researchers focus on creating single-photon sources and quantum memories using quantum dots in indium gallium arsenide and gallium arsenide, as well as color centers like nitrogen-vacancy and silicon-vacancy defects. Key applications include quantum key distribution, quantum sensing for magnetic field detection, and the development of quantum repeaters for long-distance communication. The research also encompasses advanced optical techniques such as electromagnetically induced transparency, four-wave mixing, and the use of avalanche photodiodes for single-photon detection.
The largest share of the community's output is found in rubidium research, accounting for 4.3% of all rubidium research, and 884 papers here. Indium contributes the highest paper count within this group, with 2,598 papers, representing 1.7% of all indium research.
The community comprises 22,930 papers, publishing most frequently in Applied Physics Letters, Physical Review A, and Physical Review B.
Recent work includes identifying point defects in treated single crystal diamond, developing quantum spin resonance in engineered proteins for multimodal sensing, and implementing device-independent quantum key distribution over 100 km with single atoms.
