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

Silicon spin qubits satisfy the necessary criteria for quantum information processing.
However, a demonstration of high-fidelity state preparation and readout combined with high …

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 …

Once called a 'classically non-describable two-valuedness' by Pauli, the electron spin forms
a qubit that is naturally robust to electric fluctuations. Paradoxically, a common control …

Quantum computation relies on accurate measurements of qubits not only for reading the
output of the calculation, but also to perform error correction. Most proposed scalable silicon …

The review of new formulation of conventional quantum mechanics where the quantum
states are identified with probability distributions is presented. The invertible map of density …

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 …

A short description of the notion of states of quantum systems in terms of conventional
probability distribution function is presented. The notion and the structure of entangled …

Spin qubits in gate-defined silicon quantum dots are receiving increased attention thanks to
their potential for large-scale quantum computing. Readout of such spin qubits is done most …

To push gate performance to levels beyond the thresholds for quantum error correction, it is
important to characterize the error sources occurring on quantum gates. However, the …
