Helstrom Bound for Squeezed Coherent States in Binary Communication [PDF]
Entropy, 2022 In quantum information processing, using a receiver device to differentiate between two non-orthogonal states leads to a quantum error probability. The minimum possible error is known as the Helstrom bound. In this work, we study the conditions for state

Common Coherence Witnesses and Common Coherent States. [PDF]
Entropy (Basel), 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 ...

Wigner Functions of Time-Dependent Cat-like Even/Odd Superpositions of Nonlinear Coherent States [PDF]
EntropyWe calculate and plot 2D slices of the Wigner functions of several families of highly excited even and odd superpositions of nonlinear coherent states, looking for conditions under which such superpositions can be interpreted as models of the ...

On Geometry of p-Adic Coherent States and Mutually Unbiased Bases [PDF]
Entropy, 2023 This paper considers coherent states for the representation of Weyl commutation relations over a field of p-adic numbers. A geometric object, a lattice in vector space over a field of p-adic numbers, corresponds to the family of coherent states.

Binary Communication with Gazeau–Klauder Coherent States [PDF]
Entropy, 2020 We investigate advantages and disadvantages of using Gazeau−Klauder coherent states for optical communication. In this short paper we show that using an alphabet consisting of coherent Gazeau−Klauder states related to a Kerr-type nonlinear ...

Coherent States and Duality [PDF]
Physics Letters A, 2002 We formulate a relation between quantum-mechanical coherent states and complex-differentiable structures on the classical phase space ${\cal C}$ of a finite number of degrees of freedom.

Journal of Mathematical Physics, 2002 We generalize Schwinger boson representation of SU(2) algebra to SU(N) and define coherent states of SU(N) using $2(2^{N-1}-1)$ bosonic harmonic oscillator creation and annihilation operators.

Coherent state excitations and string-added coherent states in gauge-gravity correspondence
Nuclear Physics B, 2023 We analyze detailed properties of BPS coherent states and their connection to gravity. We interpret the group integral coherent state as a path integral over auxiliary variables coupled to the elementary letters of the theory. The eigenvalues of coherent
