Nonclassicalities of the Superposition State of Coherent and Photon-Added-Coherent State [PDF]
East European Journal of PhysicsThe nonclassical properties of the hybrid coherent state (HCS), which is the superposition state of the coherent state and photon-added coherent (PAC) state, is investigated analytically.

Common Coherence Witnesses and Common Coherent States [PDF]
Entropy, 2021 We show the properties and characterization of coherence witnesses. We show methods for constructing coherence witnesses for an arbitrary coherent state. We investigate the problem of finding common coherence witnesses for certain class of states. We show that finitely many different witnesses W1,W2,⋯,Wn can detect some common coherent states if and ...

Groupoids and Coherent States [PDF]
Open Systems & Information Dynamics, 2019 Schwinger’s algebra of selective measurements has a natural interpretation in terms of groupoids. This approach is pushed forward in this paper to show that the theory of coherent states has a natural setting in the framework of groupoids. Thus given a quantum mechanical system with associated Hilbert space determined by a representation of a groupoid,

Coherent states on spheres [PDF]
Journal of Mathematical Physics, 2002 We describe a family of coherent states and an associated resolution of the identity for a quantum particle whose classical configuration space is the d-dimensional sphere Sd. The coherent states are labeled by points in the associated phase space T*(Sd).

Coherence concurrence for X states [PDF]
Quantum Information Processing, 2020 We study the properties of coherence concurrence and present a physical explanation analogous to the coherence of assistance. We give an optimal pure state decomposition which attains the coherence concurrence for qubit states. We prove the additivity of coherence concurrence under direct sum operations in another way. Using these results, we calculate

Coherence of assistance and assisted maximally coherent states [PDF]
Scientific Reports, 2021 AbstractCoherence and entanglement are fundamental concepts in resource theory. The coherence (entanglement) of assistance is the coherence (entanglement) that can be extracted assisted by another party with local measurement and classical communication. We introduce and study the general coherence of assistance.
