Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

Quantum error correction (QEC) and fault-tolerant quantum computation represent one of
the most vital theoretical aspects of quantum information processing. It was well known from …

Noise dominates every aspect of near-term quantum computers, rendering it exceedingly
difficult to carry out even small computations. In this paper we are concerned with the …

We review experimental progress on atom lasers out-coupled from Bose–Einstein
condensates, and consider the properties of such beams in the context of precision inertial …

Stochastic Schrödinger equations for quantum trajectories offer an alternative and
sometimes superior approach to the study of open quantum system dynamics. Here we …

The dynamics of a typical open quantum system, namely a quantum Brownian particle in a
harmonic potential, is studied focusing on its non-Markovian regime. Both an analytic …

Do stochastic Schrödinger equations, also known as unravelings, have a physical
interpretation? In the Markovian limit, where the system on average obeys a master …

Multi-time quantum processes are endowed with the same richness as many-body physics,
including temporal entanglement and well-defined causal structures. We dub this many-time …

A general method is developed which enables the exact treatment of the non-Markovian
quantum dynamics of open systems through a Monte Carlo simulation technique. The …

Stochastic Schrödinger equations are used to describe the dynamics of a quantum open
system in contact with a large environment, as an alternative to the commonly used master …
