Due to the variety of systems in which quantum coherence may be observed, solid state systems are the natural candidates for applications that rely on coherence, for example quantum computers. Also, several new aspects of the physics of quasi-particles are understood and discussed in this context. The coherent effects discussed mainly involve elementary excitations in solids like polaritons, excitons, magnons, macroscopic quantities like superconductor currents and electron spins. Macroscopic Quantum Coherence Atom Interferometers and Atomic Coherence (D E Pritchard et al.) Fully Quantized Treatment of Molecular Beam Resonance: Momentum. Besides being of paramount importance in fundamental physics, the study of quantum coherence furnishes the starting point for important applications like quantum computing or secure data transmission. Although quantum physics dictates the behaviour of nanoscale objects, quantum coherence, which is central to quantum information, communication and sensing, has not played an explicit role in. ( 1) Faithfulness: for all POVMs with equality if and only if A is incoherent. Based on the axiomatic quantification of coherence of states 10, we introduce a list of properties that a legitimate coherence monotone of a measurement must fulfill as follows. Our results are illustrated with several examples, including finite-dimensional systems and bosonic Gaussian states that describe recent experiments on quantum heat engines with a quantized load.This volume gives an overview of the manifestations of quantum coherence in different solid state systems, including semiconductor confined systems, magnetic systems, crystals and superconductors. Quantification of coherence in quantum measurements. We obtain bounds for both the coherent and incoherent parts of the extractable work and discuss their saturation in specific settings. Quantum coherence measures based on Fisher information with applications Lei Li, Qing-Wen Wang, Shu-Qian Shen, and Ming Li Phys. The coherence between different parts of a wave function (in momentum or real. It also paves the way to the newly emerging field of quantum thermodynamics that aims create a bridge between thermodynamics and quantum mechanics. Quantum coherence is the ability of a quantum system to demonstrate interference. Quantum coherence of an arbitrary qubit can be created at a remote location using maximally entangled state, local operation and classical communication. We show this by dividing the optimal transformation into an incoherent operation and a coherence extraction cycle. Geometrical optimization of spin clusters for the preservation of quantum coherence. Quantum coherence is an essential feature of quantum mechanics and is an important physical resource in quantum information. Quantum coherence lies at the heart of many nonintuitive quantum phenomena and is arguably the key ingredient responsible for the second quantum revolution of the 21st century. Quantum coherence is a prime resource in quantum computing and quantum communication. Specifically, we identify a coherent contribution to the ergotropy (the maximum amount of unitarily extractable work via cyclical variation of Hamiltonian parameters). Here, we isolate and study the quantum coherent component to the work yield in such protocols. Abstract protein complexes involves long-lived quantum coherence among electronic excitations of pigments. Thermodynamic cycles can, in principle, be designed to extract work from this nonequilibrium resource. In the quantum setting, finite-time control operations typically generate coherence in the instantaneous energy eigenbasis of the dynamical system. Constraints on work extraction are fundamental to our operational understanding of the thermodynamics of both classical and quantum systems. 7198 pp 10031049 In this supplement Editorial Progress Reviews Improvements in techniques to manipulate light and matter are facilitating exciting applications of.
