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.

Helstrom Bound for Squeezed Coherent States in Binary Communication
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

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.

Properties of transient spectrum and field purity for a qubit system in squeezed states
Results in Physics, 2021 The present study investigates the transient spectrum (TS) of a two-level system that interacts with a generalized squeezed state without using the rotating wave approximation (RWA).

Squeezed Coherent States in Double Optical Resonance
Photonics, 2021 In this work, we consider a “Λ-type” three-level system where the first transition is driven by a radiation field initially prepared in a squeezed coherent state, while the second one by a weak probe field. If the squeezed field is sufficiently strong to

Quantum metrology of two-photon absorption
Physical Review Research, 2021 Two-photon absorption (TPA) is of fundamental importance in super-resolution imaging and spectroscopy. Its nonlinear character allows for the prospect of using quantum resources, such as entanglement, to improve measurement precision or to gain new ...

Coherent light squeezing states within a modified microring system
Results in Physics, 2018 We have proposed the simple method of the squeezed light generation in the modified microring resonator, which is known as the microring conjugate mirror (MCM). When the monochromatic light is input into the MCM, the general form of the squeezed coherent

Squeezed vacuum interaction with an optomechanical cavity containing a quantum well
Scientific Reports, 2022 We investigate a hybrid system consisting of an optomechanical resonator and an optical cavity containing a quantum well. The system is coupled to a squeezed vacuum reservoir.

Coherent Phase States in the Coordinate and Wigner Representations
Quantum Reports, 2022 In this paper, we numerically study the coordinate wave functions and the Wigner functions of the coherent phase states (CPS), paying particular attention to their differences from the standard (Klauder–Glauber–Sudarshan) coherent states, especially in ...

Manipulation of Squeezed Two-Phonon Bound States using Femtosecond Laser Pulses
EPJ Web of Conferences, 2013 Two-phonon bound states have been excited exclusively in ZnTe(110) via impulsive stimulated second-order Raman scattering, essentially being squeezed states due to phase coherent excitation of two identical components anticorrelated in the wave vector ...
