Abstract: The analogs of optical elements in light-pulse atom interferometers are generated from the interaction of matter waves with light fields. As such, these fields possess quantum properties, which fundamentally lead to a reduced visibility in the observed interference. This loss is a consequence of the encoded information about the atom's path. However, the quantum nature of the atom-optical elements also gives an additional degree of freedom to reduce such effects: We demonstrate that entanglement between all light fields can be used to erase information about the atom's path and by that to partially recover the visibility. Thus, our work highlights the role of complementarity on atom-interferometric experiments.

Near-resonant light scattering by an atom in a state-dependent trap [0.0]
Ground state of the atom experiences a tight optical trap formed by far-off-resonant light, to facilitate efficient interactions with near-resonant light. Here, we systematically analyze the effects of unequal trapping on near-resonant atom-light interactions.

Directional spontaneous emission in photonic crystal slabs [49.1574468325115]
Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them. Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

We study the small, of the size of the order of the wavelength, interferometer with the main mode excited by a quantum field from a nano-LED or a laser. We find the field and the photon number fluctuation spectra inside and outside the interferometer. Results help the study, design, manufacture, and use small elements of quantum optical integrated circuits.

I discuss the state-of-the-art of defect centers in hexagonal boron nitride with a focus on optically coherent defect centers. The spectral transition linewidth remains unusually narrow even at room temperature. The field is put into a broad perspective with impact on quantum technology such as quantum optics, quantum photonics as well as spin optomechanics.

We study the modified propagation of light used to manipulate atoms in light-pulse atom interferometers. Their interference signal is dominated by the matter's coupling to gravity and the dilaton. We discuss effects from light propagation and the dilaton on different atom-interferometric setups.

interaction between an atomic ensemble and a light mode in a high-finesse optical cavity can easily reach the strong-coupling regime. We analyze the dominant effects on the collective atomic state and the light field. We present analytical expressions for the entanglement induced by the interaction, and determine the conditions that maximize the entanglement-induced gain.

Maximum refractive index of an atomic medium [58.720142291102135]
All optical materials with a positive refractive index have a value of index that is of order unity. Despite the giant response of an isolated atom, we find that the maximum index does not indefinitely grow with increasing density. We propose an explanation based upon strong-disorder renormalization group theory.

Quantum optics with giant atoms -- the first five years [0.0]
In quantum optics, it is common to assume atoms can be approximated as point-like compared to the wavelength of the light they interact with. Recent advances in experiments with artificial atoms built from superconducting circuits have shown that this assumption can be violated.
