Abstract: Experiments with ultracold quantum gases are a rapidly advancing research field with many applications in fundamental physics and quantum technology. Here, we report on a high-flux generation of Bose-Einstein condensate mixtures of $^{41}$K and $^{87}$Rb, using a fully integrated sounding rocket setup. We investigate the release and the free expansion of the quantum mixtures for different orientations to gravity. The release dynamics are governed by the mixture interactions as well as the decaying magnetic field during the release. The latter can be minimized by a dedicated switch-off protocol of the trap generating currents where an exact model enabled us to characterize the interaction effects. Our results establish a new benchmark for generating ultracold mixtures on mobile platforms, with direct relevance for future experiments on interacting quantum gases and tests of the equivalence principle in space.

The Kibble-Zurek mechanism captures the essential physics of nonequilibrium quantum phase transitions with symmetry breaking. We experimentally tested the KZM for the simplest quantum case, a single qubit under the Landau-Zener evolution. We report on extensive IBM-Q experiments on individual qubits embedded in different circuit environments and topologies.

Testing the equivalence principle and discreteness of spacetime through the $t^3$ gravitational phase with quantum information technology [0.0]
We propose a new thought experiment, based on present-day Quantum Information Technologies, to measure quantum gravitational effects. The technique here proposed promise to reveal gravitational field fluctuations from the analysis of the noise associated to an ideal output of a measurement process of a quantum system. We find that this setup, built with massive mesoscopic particles, can potentially reveal the $t3$ gravitational phase term and thus, the BMV effect.

Constraints on probing quantum coherence to infer gravitational entanglement [0.0]
Gravity mediated entanglement generation so far appears to be the key ingredient for a potential experiment. With measurements performed only on the atoms, a coherence revival test is proposed for verifying this entanglement generation. We explore formulations of such a protocol, and specifically find that in the envisioned regime of operation with high thermal excitation, semi-classical models, where there is no concept of entanglement, also give the same experimental signatures.

Visualizing spinon Fermi surfaces with time-dependent spectroscopy [62.997667081978825]
We propose applying time-dependent photo-emission spectroscopy, an established tool in solid state systems, in cold atom quantum simulators. We show in exact diagonalization simulations of the one-dimensional $t-J$ model that the spinons start to populate previously unoccupied states in an effective band structure. The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

We report on experimental tests of topological defect formation via the one-dimensional transverse-field Ising model. 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.
