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

Higher-Power Coherent and Squeezed States [PDF]
Optics Communications, 1999 A closed form expression for the higher-power coherent states (eigenstates of $a^{j}$) is given. The cases j=3,4 are discussed in detail, including the time-evolution of the probability densities.

Spin squeezing in nonlinear spin coherent states [PDF]
Journal of Optics B: Quantum and Semiclassical Optics, 2001 We introduce the nonlinear spin coherent state via its ladder operator formalism and propose a type of nonlinear spin coherent state by the nonlinear time evolution of spin coherent states.

Gaussian private quantum channel with squeezed coherent states. [PDF]
Sci Rep, 2015 AbstractWhile the objective of conventional quantum key distribution (QKD) is to secretly generate and share the classical bits concealed in the form of maximally mixed quantum states, that of private quantum channel (PQC) is to secretly transmit individual quantum states concealed in the form of maximally mixed states using shared one-time pad and it ...

Strong broadband intensity noise squeezing from infrared to terahertz frequencies in lasers with nonlinear dissipation [PDF]
NanophotonicsThe generation and application of squeezed light have long been central goals of quantum optics. Intensity noise squeezing of bright (coherent) states (“bright squeezing”), in contrast to squeezed vacuum, is relatively underdeveloped.

Quadrature squeezing in a nanophotonic microresonator [PDF]
Nature CommunicationsSqueezed states of light are essential for emerging quantum technology in metrology and information processing. Chip-integrated photonics offers a route to scalable and efficient squeezed light generation, however, parasitic nonlinear processes and ...

Generalized uncertainty relations and coherent and squeezed states [PDF]
Journal of the Optical Society of America A, 2000 Characteristic uncertainty relations and their related squeezed states are briefly reviewed and compared in accordance with the generalizations of three equivalent definitions of the canonical coherent states. The standard SU(1,1) coherent states are shown to be the unique states that minimize the Schroedinger uncertainty relation for every pair of the

Transactional Interpretation and the Generalized Poisson Distribution
Entropy, 2022 The aim of this paper is to study the quantum-like approach to the description of the market in the context of the principle of minimum Fisher information. We wish to investigate the validity of using squeezed coherent states as market strategies.

Implementation of Photonic Phase Gate and Squeezed States via a Two-Level Atom and Bimodal Cavity
Photonics, 2022 We propose a theoretical model for realizing a photonic two-qubit phase gate in cavity QED using a one-step process. The fidelity and probability of success of the conditional quantum phase gate is very high in the presence of cavity decay.
