Squeezed and Entangled Gluon States in QCD Jet [PDF]

open access: yesEPJ Web of Conferences, 2016
Theoretical justification for the occurrence of multimode squeezed and entan-gled colour states in QCD is given. We show that gluon entangled states which are closely related with corresponding squeezed states can appear by the four-gluon self ...

Squeezed comb states [PDF]

open access: yes, 2021
Continuous-variable codes are an expedient solution for quantum information processing and quantum communication involving optical networks. Here we characterize the squeezed comb, a finite superposition of equidistant squeezed coherent states on a line,

Squeezed-light interferometry on a cryogenically-cooled micro-mechanical membrane [PDF]

open access: yes, 2020
Squeezed states of light reduce the signal-normalized photon counting noise of measurements without increasing the light power and enable fundamental research on quantum entanglement in hybrid systems of light and matter.

Two-axis two-spin squeezed states

open access: yesPhysical Review Research, 2020
The states generated by the two-spin generalization of the two-axis countertwisting Hamiltonian are examined. We analyze the behavior at both short and long timescales, by calculating various quantities such as squeezing, spin expectation values ...

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 ...

Squeezed vacuum interaction with an optomechanical cavity containing a quantum well

open access: yesScientific 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.

Control of squeezed states

open access: yesProceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
In this paper we consider the classical and quantum control of squeezed states of harmonic oscillators. This provides a method for reducing noise below the quantum limit and provides an example of the control of under-actuated systems in the stochastic and quantum context.

Quantum metrology of two-photon absorption

open access: yesPhysical 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 ...

Optimal quantum noise cancellation with an entangled witness channel

open access: yesPhysical Review Research, 2021
We present the digital signal processing of a mutually entangled, two-mode squeezed state using Wiener filtering to maximize the reduction of quantum noise of a single mode. By conditioning this mode, the signal, with its directly detected entangled pair,
