Quantum state reconstruction of an intense polarization squeezed state

open access: yes, 2006
The first quantum reconstruction of an intense Kerr squeezed state is reported. Taking into account the algebraic properties of the Stokes operators, the Wigner function describing a polarization squeezed state can also be fully reconstructed.

STATISTICAL PROPERTIES OF SINGLE-MODE DISPLACED SQUEEZED VACUUM STATE [PDF]

open access: yes, 2021
In this paper the displaced squeezed vacuum state is produced by application of displaced operator on squeezed vacuum state. With help of density operator we find Q function, with the Q function mean, variance and quadrature variance would be calculated.

Observation of Localized Multi-Spatial-Mode Quadrature Squeezing

open access: yesPhysical Review X, 2015
Quantum states of light can improve imaging whenever the image quality and resolution are limited by the quantum noise of the illumination. In the case of a bright illumination, quantum enhancement is obtained for a light field composed of many squeezed ...

Squeezed-light interferometry on a cryogenically-cooled micro-mechanical membrane

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.

Experimental study of decoherence of the two-mode squeezed vacuum state via second harmonic generation

open access: yesPhysical Review Research, 2021
Decoherence remains one of the most serious challenges to the implementation of quantum technology. It appears as a result of the transformation over time of a quantum superposition state into a classical mixture due to the quantum system interacting ...

Experimental Demonstration of Gaussian Boson Sampling with Displacement

open access: yesPRX Quantum, 2022
Gaussian boson sampling (GBS) is a quantum sampling task in which one has to draw samples from the photon-number distribution of a large-dimensional nonclassical squeezed state of light. In an effort to make this task intractable for a classical computer,
