We develop a notion of stochastic quantum trajectories. First, we construct a basis set of trajectories, called elementary trajectories, and go on to show that any quantum dynamical process, including those that are non-Markovian, can be expressed as a linear combination of this set. We then show that the set of processes divide into two natural classes: those that can be expressed as a convex mixture of elementary trajectories and those that cannot be. The former are shown to be entanglement… 

When Is a Non-Markovian Quantum Process Classical?

More than a century after the inception of quantum theory, the question of which traits and phenomena are fundamentally quantum remains under debate. Here we give an answer to this question for

Quantum Stochastic Processes and Quantum non-Markovian Phenomena

The field of classical stochastic processes forms a major branch of mathematics. They are, of course, also very well studied in biology, chemistry, ecology, geology, finance, physics, and many more

Thermodynamics of Quantum Causal Models: An Inclusive, Hamiltonian Approach

It is demonstrated that the first and second law hold for an even wider range of scenarios than previously thought, covering a large class of quantum causal models based solely on a single assumption about the initial system-bath state.

Reconstructing non-Markovian quantum dynamics with limited control

The dynamics of an open quantum system can be fully described and tomographically reconstructed if the experimenter has complete control over the system of interest. Most real-world experiments do

Demonstration of non-Markovian process characterisation and control on a quantum processor

This work develops a framework for characterising non-Markovian dynamics in quantum systems and experimentally test it on multi-qubit superconducting quantum devices, showing it leads to superior quantum control and extension of coherence time by effective decoupling from the non- Markovian environment.

Operational approach to quantum stochastic thermodynamics.

The theory is used to compute the thermodynamic efficiency of recent experiments reporting on the stabilization of photon number states using real-time quantum feedback control and points out various interesting problems, which the theory is able to address rigorously, including the detection of quantum effects in thermodynamics.

This paper solves the long standing question of unambiguously describing the memory length of a quantum processes and introduces an instrument-specific notion of memory strength that allows for a meaningful quantification of the temporal correlations between the history and the future of a process for a given choice of experimental intervention.

Experimental non-Markovian process characterisation and control on a quantum processor

This work develops and experimentally test a framework for characterising non-Markovian dynamics in quantum systems, based on the recently proposed process tensor, and demonstrates that the dynamical characterisation remains high in fidelity where conventional Markovian characterisation models suffer from an appreciable reduction in quality.

Statistics of projective measurement on a quantum probe as a witness of noncommutativity of algebra of a probed system

We consider a quantum probe P undergoing pure dephasing due to its interaction with a quantum system S . The dynamics of P is then described by a well-defined sub-algebra of operators of S, i.e. the

Resource theories of multi-time processes: A window into quantum non-Markovianity

This work investigates the conditions under which an uncontrollable background processes may be harnessed by an agent to perform a task that would otherwise be impossible within their operational framework, and proposes a resource theory of quantum processes across multiple points in time.

It is shown how a multi-time non-Markovian process can be reconstructed experimentally, and that it has a natural representation as a many body quantum state, where temporal correlations are mapped to spatial ones.

Minimal entropy of states emerging from noisy quantum channels

It is proved that for a tensor product of two unital stochastic maps on qubit states, using an entanglement that involves only states which emerge with minimal entropy cannot decrease the entropy below the minimum achievable using product states.

Entanglement and non-markovianity of quantum evolutions.

Two different measures of non-markovianity are introduced that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts when complete tomographic knowledge about the evolution is available and when no information whatsoever is available.
