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

Quantum computers have the potential to efficiently solve problems in logistics, drug and
material design, finance, and cybersecurity. However, millions of qubits will be necessary for …

Scaling up invariably error-prone quantum processors is a formidable challenge. Although
quantum error correction ultimately promises fault-tolerant operation, the required qubit …

We detect correlations in qubit-energy fluctuations of non-neighboring qubits defined in
isotopically purified Si/Si-Ge quantum dots. At low frequencies (where the noise is …

Semiconductor qubits have a small footprint and so are appealing for building densely
integrated quantum processors. However, fabricating them at high densities raises the issue …

Noise that exhibits significant temporal and spatial correlations across multiple qubits can be
especially harmful to both fault-tolerant quantum computation and quantum-enhanced …

Topology-related ideas might lead to noise-resilient quantum computing. For example, it is
expected that the slow spatial exchange (“braiding”) of Majorana zero modes in …

Spin qubits are contenders for scalable quantum computation because of their long
coherence times demonstrated in a variety of materials, but individual control by frequency …

Benchmarking and characterizing quantum states and logic gates is essential in the
development of devices for quantum computing. We introduce a Bayesian approach to self …

Solid-state qubits incorporating quantum dots can be read out dispersively. Here, we
theoretically describe physical mechanisms that render such reflectometry-based readout …
