Semiconductor spin qubits

Spin qubits, employing the fundamental quantum property of intrinsic angular momentum individual electrons and nuclei, continue to develop evolve. Lithographically patterned semiconductor chips play host spin-qubit systems in which long coherence times, high-fidelity gates, single-shot measurement are now routine. This review summarizes progress four current qubit types: single spin donor singlet triplet exchange-only qubits. All have been boosted by advances mesoscopic physics. On other hand, all still need address challenges further progress, such as mitigation noise establishment long-distance entanglement.
