The future development of quantum technologies relies on creating and manipulating quantum systems of increasing complexity, with key applications in computation, simulation …
We present an extensive introduction to quantum collision models (CMs), also known as repeated interactions schemes: a class of microscopic system–bath models for investigating …
Quantum dynamical maps provide suitable mathematical representation of quantum evolutions. When representing quantum states by density operators, the evident …
Crosstalk occurs in most quantum computing systems with more than one qubit. It can cause a variety of correlated and nonlocal $\textit {crosstalk errors} $ that can be especially harmful …
The field of classical stochastic processes forms a major branch of mathematics. Stochastic processes are, of course, also very well studied in biology, chemistry, ecology, geology …
The presence of noise or the interaction with an environment can radically change the dynamics of observables of an otherwise isolated quantum system. We derive a bound on …
The dynamical convergence of a system to the thermal distribution, or Gibbs state, is a standard assumption across all of the physical sciences. The Gibbs state is determined just …
In the scale-up of quantum computers, the framework underpinning fault-tolerance generally relies on the strong assumption that environmental noise affecting qubit logic is uncorrelated …
Characterization protocols have so far played a central role in the development of noisy intermediate-scale quantum (NISQ) computers capable of impressive quantum feats. This …
