Pullback Coherent States, Squeezed States and Quantization

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2022
In this semi-expository paper, we define certain Rawnsley-type coherent and squeezed states on an integral Kähler manifold (after possibly removing a set of measure zero) and show that they satisfy some properties which are akin to the maximal likelihood

Higher-power coherent and squeezed states [PDF]

open access: yesOptics Communications, 2000
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. These are compared to the case j=2, the even- and odd-coherent states. We give the extensions to the "effective" displacement-operator, higher-power squeezed

Coherent Phase States in the Coordinate and Wigner Representations

open access: yesQuantum 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

open access: yesEPJ 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 ...

Collapse and Revival of n-Photon Coherent States and n-Photon Squeezed Coherent States [PDF]

open access: yes, 2022
We introduce the set of n-photon coherent states and the set of n-photon squeezed coherent states and study their collapse and revival and compare their behavior with the collapse and revival of the corresponding zero-photon coherent states and zero ...

Basic properties of coherent-squeezed states revisited [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2014
In this paper, we treat coherent-squeezed states of Fock space once more and study some basic properties of them from a geometrical point of view. Since the set of coherent-squeezed states {|α, β〉|α, β ∈ C} makes a real four-dimensional surface in the Fock space ℱ (which is of course not flat), we can calculate its metric.

Scattering-lens based quantum imaging beyond shot noise

open access: yesScientific Reports, 2021
The scheme of optical imaging using scattering lens can provide a resolution beyond the classical optical diffraction limit with a coherent-state input.

Generation and Measurement of Squeezed Vacuum States at Audio-Band Frequencies

open access: yesApplied Sciences, 2019
Squeezed vacuum states at audio-band frequencies are important quantum resources for practical applications. We demonstrated the generation of squeezed vacuum states at the audio-band frequencies from a subthreshold optical parametric oscillator with a ...

On the Isomorphism between Dissipative Systems, Fractal Self-Similarity and Electrodynamics. Toward an Integrated Vision of Nature

open access: yesSystems, 2014
In electrodynamics there is a mutual exchange of energy and momentum between the matter field and the electromagnetic field and the total energy and momentum are conserved.

Squeezing-enhanced communication without a phase reference [PDF]

open access: yesQuantum, 2021
We study the problem of transmitting classical information using quantum Gaussian states on a family of phase-noise channels with a finite decoherence time, such that the phase-reference is lost after $m$ consecutive uses of the transmission line.
