The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

Abstract This Technical Review collects values of selected performance characteristics of
semiconductor spin qubits defined in electrically controlled nanostructures. The …

Full-scale quantum computers require the integration of millions of qubits, and the potential
of using industrial semiconductor manufacturing to meet this need has driven the …

Quantum computation features known examples of hardware acceleration for certain
problems, but is challenging to realize because of its susceptibility to small errors from noise …

Quantum entanglement is a fundamental property of coherent quantum states and an
essential resource for quantum computing. In large-scale quantum systems, the error …

Arbitrarily long quantum computations require quantum memories that can be repeatedly
measured without being corrupted. Here, we preserve the state of a quantum memory …

Qubits that can be efficiently controlled are essential for the development of scalable
quantum hardware. Although resonant control is used to execute high-fidelity quantum …

We identify the dominant source for low-frequency spin qubit splitting noise in a highly
isotopically-purified silicon device with an embedded nanomagnet and a spin echo decay …

Silicon quantum dots are attractive for the implementation of large spin-based quantum
processors in part due to prospects of industrial foundry fabrication. However, the large …

Quantum systems must be prepared, controlled, and measured with high fidelity in order to
perform complex quantum algorithms. Control fidelities have greatly improved in silicon spin …
