Quantum non-Gaussianity criteria based on vacuum probabilities of original and attenuated state

New Journal of Physics, 2021
Quantum non-Gaussian states represent an important class of highly non-classical states whose preparation requires quantum operations or measurements beyond the class of Gaussian operations and statistical mixing.

Movement and Fluctuations of the Vacuum [PDF]

, 1997
Quantum fields possess zero-point or vacuum fluctuations which induce mechanical effects, namely generalised Casimir forces, on any scatterer. Symmetries of vacuum therefore raise fundamental questions when confronted with the principle of relativity ...

QUANTUM VACUUM AND ANOMALIES [PDF]

International Journal of Modern Physics A, 1995
Chiral, conformal and ghost number anomalies are discussed from the viewpoint of the quantum vacuum in Hamiltonian formalism. After introducing the energy cutoff, we derive known anomalies in a new way. We give an interpretation of the anomalies in connection with the zero-point fluctuation of bosonic or fermionic field.

Boiling Quantum Vacuum: Thermal Subsystems from Ground-State Entanglement

PRX Quantum, 2022
In certain special circumstances, such as in the vicinity of a black hole or in a uniformly accelerating frame, vacuum fluctuations appear to give rise to a finite-temperature environment.

The Quantum Yang–Mills Theory

Universe, 2023
In axiomatic quantum field theory, the postulate of the uniqueness of the vacuum (a pure vacuum state) is independent from the other axioms and equivalent to the cluster decomposition property. The latter, however, implies a Coulomb or Yukawa attenuation

Sonoluminescence as Quantum Vacuum Radiation [PDF]

Physical Review Letters, 1996
Sonoluminescence is explained in terms of quantum radiation by moving interfaces between media of different polarizability. It can be considered as a dynamic Casimir effect, in the sense that it is a consequence of the imbalance of the zero-point fluctuations of the electromagnetic field during the non-inertial motion of a boundary.

BQP-completeness of scattering in scalar quantum field theory [PDF]

Quantum, 2018
Recent work has shown that quantum computers can compute scattering probabilities in massive quantum field theories, with a run time that is polynomial in the number of particles, their energy, and the desired precision.

CRITICAL ACCELERATION AND QUANTUM VACUUM [PDF]

Towards Ultimate Understanding of the Universe, 2013
Little is known about the physics frontier of strong acceleration; both classical and quantum physics need further development in order to be able to address this newly accessible area of physics. In this lecture we discuss what strong acceleration means, possible experiments using electron-laser collisions, and data available from ultra-relativistic ...

Quantum coherence of a circularly accelerated atom in a spacetime with a reflecting boundary

Scientific Reports, 2022
We investigate, in the paradigm of open quantum systems, the dynamics of quantum coherence of a circularly accelerated atom coupled to a bath of vacuum fluctuating massless scalar field in a spacetime with a reflecting boundary.
