Title: Entangled vacuum state for accelerated observers
Authors: Leyli Esmaelifar, Behrouz Mirza and Zahra Ebadi
Abstract summary: Entanglement of Dirac fields has been studied and it is known to decrease with increasing acceleration when a quantum state is shared between users in non-inertial frames. A new form of an entangled vacuum state is postulated in which it is assumed that entanglement is present between the modes of the quantum field with sharp and opposite momenta defined in two causally disconnected regions of space-time.

Abstract: Entanglement of Dirac fields has been studied and it is known to decrease with increasing acceleration when a quantum state is shared between users in non-inertial frames. A new form of an entangled vacuum state observed by the accelerated observer is postulated in which it is assumed that entanglement is present between the modes of the quantum field with sharp and opposite momenta defined in two causally disconnected regions of space-time. We find that this assumption does not affect the entanglement of the system.

Fate of the spatial-temporal order under quantum fluctuation [3.8121150313479655]
We investigate the dynamics beyond mean-field approximation. Results show that the spatial-temporal lattice is melted in the mean-field level but survives in the quantum fluctuation.

The behavior of quantum entanglement during scattering is identical to the behavior of initially classically correlated photons up to a constant factor equal to two. Our dedicated experiment with photons confirms these results and explains the "Puzzle of Decoherence" observed recently.

Measurement phase transitions in the no-click limit as quantum phase transitions of a non-hermitean vacuum [77.34726150561087]
We study phase transitions occurring in the stationary state of the dynamics of integrable many-body non-Hermitian Hamiltonians. We observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

We study theoretically repelling quantum states of two spinless particles in a one-dimensional tight-binding model. We demonstrate, that when the particles are not identical, their interaction drives nontrivial correlated two-particle states.

Controlling and measuring a superposition of position and momentum [0.2578242050187029]
We show that a lower bound on the probability of finding a particle after propagating for a given time is 5.9% below a classical bound. We prepared a superposition of position and momentum states by using slits, lenses and an interferometer, and observed a quantum interference between position and momentum.

Detection of quantum-vacuum field correlations outside the light cone [0.0]
According to quantum field theory, empty space is not empty at all, but filled with quantum-vacuum fluctuations. We experimentally demonstrate the existence of correlations of the vacuum fields for non-causally connected space-time points. This work marks a first step in analyzing the space-time structure of vacuum correlations in quantum field theory.

Continuous-variable quantum teleportation with vacuum-entangled Rindler modes [0.0]
We consider a continuous-variable quantum teleportation protocol between a uniformly accelerated sender in the right Rindler wedge and an inertial observer in the Minkowski vacuum. We find that a Rindler-displaced Minkowski vacuum state prepared and teleported by the accelerated observer appears mixed according to the inertial observer.
