Conditioning of Quantum Open Systems [PDF]
, 2020 The underlying probabilistic theory for quantum mechanics is non-Kolmogorovian. The order in which physical observables will be important if they are incompatible (non-commuting). In particular, the notion of conditioning needs to be handled with care and may not even exist in some cases. Here we layout the quantum probabilistic formulation in terms of

Simulation of open quantum systems [PDF]
EPL (Europhysics Letters), 2009 We present an approach for the semiclassical treatment of open quantum systems. An expansion into localized states allows restriction of a simulation to a fraction of the environment that is located within a predefined vicinity of the system. Adding and dropping environmental particles during the simulation yields an effective reduction of the size of ...

Digital Simulation of Single Qubit Markovian Open Quantum Systems: A Tutorial
Quanta, 2023 One of the first proposals for the use of quantum computers was the simulation of quantum systems. Over the past three decades, great strides have been made in the development of algorithms for simulating closed quantum systems and the more complex open

Stabilizer codes for open quantum systems
Scientific Reports, 2023 AbstractThe Lindblad master equation describes the evolution of a large variety of open quantum systems. An important property of some open quantum systems is the existence of decoherence-free subspaces. A quantum state from a decoherence-free subspace will evolve unitarily.

Digital Quantum Simulation of Open Quantum Systems Using Quantum Imaginary–Time Evolution
PRX Quantum, 2022 Quantum simulation on emerging quantum hardware is a topic of intense interest. While many studies focus on computing ground-state properties or simulating unitary dynamics of closed systems, open quantum systems are an interesting target of study owing ...

Multipartite quantum correlations in open quantum systems [PDF]
New Journal of Physics, 2013 In this paper we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions. Our measure can be defined for quantum discord (QD), geometric quantum discord (GQD), or even by the entanglement of formation (EOF).

Simulation of open-quantum-system dynamics using the quantum Zeno effect
Physical Review Research, 2020 We suggest a quantum simulator that allows to study the role of memory effects in the dynamics of open quantum systems. A particular feature of our simulator is the ability to engineer both Markovian and non-Markovian dynamics by means of quantum ...
