Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

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-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

Quantum metrology holds the promise of an early practical application of quantum
technologies, in which measurements of physical quantities can be made with much greater …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Reinvigorated by advances and insights, in particular from the active fields of quantum
information and computing, the quantum theory of irreversible processes has recently …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

We extend the quantum discord to continuous variable systems and evaluate Gaussian
quantum discord C (ϱ) for bipartite Gaussian states. In particular, for squeezed-thermal …

Excitation transfer through interacting systems plays an important role in many areas of
physics, chemistry, and biology. The uncontrollable interaction of the transmission network …

Open systems of coupled qubits are ubiquitous in quantum physics. Finding a suitable
master equation to describe their dynamics is therefore a crucial task that must be …
