Spin Based Quantum Technologies

The spin degree of freedom provides a natural two-level system that can be used as qubits. The spins are isolated from the environment and provide a long coherence time. Coherent t control of spin qubits can be achieved by a resonant microwave field. Efficient readout of electron and nuclear spin can be realized using optically based approaches, electrical readout and microwave cavity-based readout. Scaling of spin-qubit based systems can be achieved based on dipolar or exchange coupling as well as long range cavity mediated microwave coupling. Examples of promising spin qubits include electrons in semiconductor quantum dots, spins associated with colour centres in wide-band gap semiconductors, molecular electron and nuclear spins.This research topic will cover recent progress in the fabrication of spin qubits, their characterization and the application of spin-based quantum registers in quantum science and technology.Specific areas of interest to this Research Topic include:Spin qubits for quantum sensingSpin qubits for quantum computingSpin qubits as long living quantum memory for light matter quantum interfacesSingle atom dopingSynthesis of molecular qubitsIsotopic engineering of materials for spin qubits applicationsNew spin qubits characterization techniques Dynamical decoupling technique for spin qubits.Device integration of spin-based quantum systemsReadout of spin based quantum systems Topic editors: Stefania Castelletto, Takeshi Ohshima, Fedor Jelezko, Brant Gibson Source: https://www.frontiersin.org/research-topics/70589/spin-based-quantum-technologies
