- Abstract summary: We implement a high-quality Bell experiment during a parabolic flight, transitioning from microgravity to hypergravity of 1.8 g.
We observe Bell violation, with Bell-CHSH parameters between $S=-2.6202$ and $-2.7323$, an average of $overlineS = -2.680$, and average standard deviation of $overlineDelta S = 0.014$.
This experiment demonstrates the stability of current quantum communication platforms for space-based applications.

- Abstract: Quantum technologies have matured to the point that we can test fundamental
quantum phenomena under extreme conditions. Specifically, entanglement, a
cornerstone of modern quantum information theory, can be robustly produced and
verified in various adverse environments. We take these tests further and
implement a high-quality Bell experiment during a parabolic flight,
transitioning from microgravity to hypergravity of 1.8 g while continuously
observing Bell violation, with Bell-CHSH parameters between $S=-2.6202$ and
$-2.7323$, an average of $\overline{S} = -2.680$, and average standard
deviation of $\overline{\Delta S} = 0.014$. This violation is unaffected both
by uniform and non-uniform acceleration. This experiment demonstrates the
stability of current quantum communication platforms for space-based
applications and adds an important reference point for testing the interplay of
non-inertial motion and quantum information.

In two-level quantum systems - qubits - unitary dynamics theoretically limit these quantum correlations to $2qrt2$ or 1.5 respectively.
Here, using a dissipative, trapped $40$Ca$+$ ion governed by a two-level, non-Hermitian Hamiltonian, we observe correlation values up to 1.703(4) for the Leggett-Garg parameter $K_3$.
These excesses occur across the exceptional point of the parity-time symmetric Hamiltonian responsible for the qubit's non-unitary, coherent dynamics.

Entanglement is a fundamental resource that allows quantum sensors to surpass the standard quantum limit set by the quantum collapse of independent atoms.
Collective cavity-QED systems have succeeded in generating large amounts of directly observed entanglement involving the internal degrees of freedom of laser-cooled atomic ensembles.
An entangled state is for the first time successfully injected into a Mach-Zehnder light-pulse interferometer with $1.7+0.5_-0.5$ dB of directly observed metrological enhancement.

We study a range of different experimental set-ups, considering different geometries and the number of spatially superposed states taken, in order to determine which would generate entanglement faster.
We conclude that without decoherence, and given a maximum distance $Delta x$ between any two spatial states of a superposition, a set of two qubits placed in spatial superposition parallel to one another will outperform all other models.

We find that the quantum simulator results can indeed be explained by the KZM for open-system quantum dynamics with phase-flip errors.
This implies that the theoretical predictions of the generalized KZM theory, which assumes isolation from the environment, applies beyond its original scope to an open system.
