# Decoherence, the measurement problem, and interpretations of quantum mechanics

@article{Schlosshauer2005DecoherenceTM, title={Decoherence, the measurement problem, and interpretations of quantum mechanics}, author={Maximilian Schlosshauer}, journal={Reviews of Modern Physics}, year={2005}, volume={76}, pages={1267-1305} }

Environment-induced decoherence and superselection have been a subject of intensive research over the past two decades, yet their implications for the foundational problems of quantum mechanics, most notably the quantum measurement problem, have remained a matter of great controversy. This paper is intended to clarify key features of the decoherence program, including its more recent results, and to investigate their application and consequences in the context of the main interpretive…

We investigate the meaning of gravity-induced decoherence in quantum theory, known as ‘intrinsic’ or ‘fundamental’ decoherence in the literature. We explore a range of issues relevant to this…

Fundamental decoherence from quantum gravity: a pedagogical review

We present a discussion of the fundamental loss of unitarity that appears in quantum mechanics due to the use of a physical apparatus to measure time. This induces a decoherence effect that is…

Compatibility between Environment-Induced Decoherence and the Modal-Hamiltonian Interpretation of Quantum Mechanics

The modal-Hamiltonian interpretation (MHI) has proved to be effective for solving several interpretative problems, but since its actualization rule applies to closed systems, it seems to stand at odds with EID.

Coherence protection in coupled quantum systems

The interaction of a quantum system with its environment causes decoherence, setting a fundamental limit on its suitability for quantum information processing. However, we show that if the system…

A definition of decoherence is studied which incorporates both of these ideas, and shows that it leads to a consistent probabilistic interpretation of the reduced density operator.

The Basis Problem in Many-Worlds Theories

- Philosophy

The core basis problem is that the robust enduring states specified by environmental decoherence effects are essentially Gaussian wave packets that form continua of non-orthogonal states that are not a discrete set of orthogonal basis states.

In the last decade decoherence has become a very popular topic mainly due to the progress in experimental techniques which allow monitoring of the process of decoherence for single microscopic or…

Quantum Limit of Decoherence: Environment Induced Superselection of Energy Eigenstates

We investigate decoherence in the limit where the interaction with the environment is weak and the evolution is dominated by the self-Hamiltonian of the system. We show that in this case quantized…
