Quadrature squeezing and information entropy squeezing in nonlinear two-level spin models
(World Scientific, 2010-04)
Normal squeezing, variance and entropy squeezing factors based on the Heisenberg uncertainty principle and Shannon information entropy theory, respectively, derived from the entangled states of two-mode coherent states in ...
Atomic entropy squeezing in three-level systems
We consider the problem of an atomic three-level system (in a ladder configuration) interacting with a radiation field. Assuming a coherent state as the initial state, we solve exactly the time evolution of the system. We ...
Variance squeezing and information entropy squeezing via Bloch coherent states in two-level nonlinear spin models
(Elsevier Gmbh, 2014-10)
The nonclassical squeezing effect emerging from a nonlinear coupling model (generalized Jaynes–Cummings model) of a two-level atom interacting resonantly with a bimodal cavity field via two-photon transitions is investigated ...
Information entropy and spin-squeezing in atomic three-level systems
(World Scientific, 2013-07)
We consider the problem of an atomic three-level system in interaction with a radiation field. The time evolution of the system, in atomic ladder and Λ configurations, is solved exactly assuming a coherent-state as the ...
Planar quantum squeezing in spin-1/2 systems
(IOP Publishing, 2015-10)
Planar quantum squeezed (PQS) states, i.e. quantum states which are squeezed in two orthogonal spin components on a plane, have recently attracted attention due to their applications in atomic interferometry and quantum ...
GENERATION OF DECOHERENCE-FREE DISPLACED SQUEEZED STATES OF RADIATION FIELDS AND A SQUEEZED RESERVOIR FOR ATOMS IN CAVITY QED
(AMERICAN PHYSICAL SOCIETY, 2008)
MECÁNICA CUÁNTICA DE LOS ESTADOS COHERENTES Y COMPRIMIDOS
We formally developed the theory of coherent and squeezed states for the harmonic oscillator. This was based on the Weyl operator (related to the Heisenberg – Weyl group 1 ), and squeezing operator (related ...
Disappearance of squeezed back-to-back correlations: a new signal of hadron freeze-out from a supercooled quark gluon plasma
(Sociedade Brasileira de Física, 2014)
Transmission estimation at the cram´er-rao bound for squeezed states of light in the presence of loss and imperfect detection
(American Physical Society, 2020)
Enhancing the precision of a measurement requires maximizing the information that can be gained about the quantity of interest from probing a system. For optical-based measurements, such an enhancement can be achieved ...
Manipulation of multimode squeezing in a coupled waveguide array
(American Physical Society, 2019)
© 2019 American Physical Society. ©2019 American Physical Society.We present a scheme for generating and manipulating three-mode squeezed states with genuine tripartite entanglement by injecting single-mode squeezed light ...
