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 …

As quantum processors grow in complexity, attention is moving to the scaling prospects of
the entire quantum computing system, including the classical support hardware. Recent …

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

Semiconductor spins are one of the few qubit realizations that remain a serious candidate
for the implementation of large-scale quantum circuits. Excellent scalability is often argued …

We introduce a scheme for preparation, manipulation, and read out of Majorana zero modes
in semiconducting wires with mesoscopic superconducting islands. Our approach …

Recent advances in quantum error correction codes for fault-tolerant quantum computing
and physical realizations of high-fidelity qubits in multiple platforms give promise for the …

As quantum computers grow in complexity, the technology will have to evolve from large
distributed systems to compact integrated solutions. Spin qubits in silicon quantum dots are …

The spin states of single electrons in gate-defined quantum dots satisfy crucial requirements
for a practical quantum computer. These include extremely long coherence times, high …

Interacting fermions on a lattice can develop strong quantum correlations, which are the
cause of the classical intractability of many exotic phases of matter,,. Current efforts are …

We present designs for scalable quantum computers composed of qubits encoded in
aggregates of four or more Majorana zero modes, realized at the ends of topological …
