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

Quantum technologies represent a rapidly evolving field in which the specific properties of
quantum mechanical systems are exploited to enhance the performance of various …

Dynamical decoupling (DD) is perhaps the simplest and least resource-intensive error-
suppression strategy for improving quantum computer performance. Here we report on a …

Currently available superconducting quantum processors with interconnected transmon
qubits are noisy and prone to various errors. The errors can be attributed to sources such as …

We introduce a new approach for the robust control of quantum dynamics of strongly
interacting many-body systems. Our approach involves the design of periodic global control …

Decoherence is one of the most important obstacles that must be overcome in quantum
information processing. It depends on the qubit-environment coupling strength, but also on …

Dynamical decoupling (DD) is a popular technique for protecting qubits from the
environment. However, unless special care is taken, experimental errors in the control …

This chapter provides an introduction to the theory of decoherence‐free subspaces (DFSs),
noiseless subsystems (NSs), and dynamical decoupling (DD)–the key tools for decoherence …

Quantum computers, which process information encoded in quantum mechanical systems,
hold the potential to solve some of the hardest computational problems. A substantial …

Over the past decade we have seen an explosion of demonstrations of quantum coherence
in atomic, optical and condensed matter systems. These developments have placed a new …
