Solid-State Spin Qubits and Quantum Sensors in Diamond, Silicon and Silicon Carbide
This community develops hardware for quantum computing and sensing using specific defects and impurities in diamond, silicon, and silicon carbide, focusing on controlling individual electron spins to process information or detect physical fields.
The work centers on creating and manipulating spin qubits in silicon and silicon carbide, and utilizing color centers, particularly nitrogen-vacancy centers, in diamond for quantum sensing. Recurring methods include chemical vapor deposition for growing diamond films, ion implantation for doping, and the fabrication of quantum dots and thin films. Applications range from high-fidelity quantum processors and entangled network nodes to magnetometry, nanothermometry, and bioinert sensors. The research also encompasses the synthesis of nanodiamonds and the optimization of surface properties for electrochemical and photoconductive performance, bridging materials engineering with quantum device physics.
The community is most prominent in silicon research, where it constitutes 2.5% of all tracked silicon papers, and in boron research, also at a 2.5% share. It contributes 2,676 papers to the silicon element record, which is the highest raw count among the elements it touches.
The community comprises 14,023 papers, publishing most frequently in Diamond and Related Materials, Applied Physics Letters, and Journal of Applied Physics.
Recent work includes industry-compatible silicon spin-qubit unit cells, non-invasive bioinert quantum sensors from silicon carbide, and millikelvin intracellular nanothermometry using nanodiamonds.
