Quantum-enhanced measurements without entanglement
Quantum-enhanced measurements exploit quantum mechanical effects for increasing the sensitivity of measurements of certain physical parameters and have great potential for both fundamental scienceExpand
Irreversible Quantum Dynamics
Quantum Theory of Irreversibility: Open Systems and Continuum Mechanics.- Selected Aspects of Markovian and Non-Markovian Quantum Master Equations.- Aspects of Open Quantum Dynamics.- Concepts andExpand
Quantum symmetries of q‐difference equations
A general method is presented to determine the symmetry operators of linear q‐difference equations. It is applied to q‐difference analogs of the Helmoltz, heat, and wave equations in diverseExpand
Quantum Information, Computation and Cryptography: An Introductory Survey of Theory, Technology and Experiments
TLDR
This multi-authored textbook addresses graduate students with a background in physics, mathematics or computer science and brings together different points of view from various renowned experts, providing a coherent picture of the subject matter. Expand
OPEN QUANTUM DYNAMICS: COMPLETE POSITIVITY AND ENTANGLEMENT
We review the standard treatment of open quantum systems in relation to quantum entanglement, analyzing, in particular, the behavior of bipartite systems immersed in the same environment. We firstExpand

Completely positive dynamical maps and the neutral kaon system
Abstract The evolution of quantum irreversible processes can be effectively described using dynamical semigroups. They involve non-unitary time evolutions of density matrices that are generated byExpand
Redfield reduced dynamics and entanglement
In phenomenological applications, the time evolution of subsystems immersed in an external environment is sometimes described by Markovian semigroups of the Redfield type that have non-positiveExpand
q-Orthogonal polynomials and the oscillator quantum group
The oscillator quantum algebra is shown to provide a group-theoretic setting for the q-Laguerre and q-Hermite polynomials.
Palatini formalism and new canonical variables for GL(4) invariant gravity
In the context of a recently proposed GL(4)-invariant formulation of general relativity the authors discuss a generalized Palatini formalism in which the conditions of metricity and torsionlessnessExpand
