Experimental quantum decoherence control by dark states of the environment
Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system–environment coupling can be simultaneously explored to engineer a specific dark state of the

Coupled Harmonic Oscillator in a System of Free Particles
The coupled quantum harmonic oscillator is one of the most researched and important model systems in quantum optics and quantum informatics. This system is often investigated for quantum entanglement in the environment.

Early transverse decoherence of bunches with space charge
The transverse decoherence of injected bunches is an important phenomenon in synchrotrons and storage rings. The initial stage of this process determines the transverse emittance blowup, which should be taken into account for the design of feedback ...

Decoherence without dissipation [PDF]
That decoherence can take place in the presence of energy conservation seems to be a poorly known fact. That lack of knowledge has, for example, bedevilled the discussion of the ‘black hole information’ problem. I present a simple model that illustrates such energy-free decoherence.

Quantifying Decoherence via Increases in Classicality
As a direct consequence of the interplay between the superposition principle of quantum mechanics and the dynamics of open systems, decoherence is a recurring theme in both foundational and experimental exploration of the quantum realm.

Decoherence due to gravitational time dilation: analysis of competing decoherence effects [PDF]
Recently, a static gravitational field, such as that of the Earth, was proposed as a new source of decoherence [1]. We study the conditions under which it becomes the dominant decoherence effect in typical interferometric experiments.

Indirect decoherence in optical lattices and cold gases [PDF]
The interaction of two--level atoms with a common heat bath leads to an effective interaction between the atoms, such that with time the internal degrees of the atoms become correlated or even entangled.

Abstract In quantum information theory, quantum discord has been proposed as a tool to characterise the presence of “quantum correlations” between the subparts of a given system. Whether a system behaves quantum-mechanically or classically is believed to be impacted by the phenomenon of decoherence, which originates from the unavoidable ...
