Abstract: We report here on the realization of light-pulse atom interferometers with Large-momentum-transfer atom optics based on a sequence of Bragg transitions. We demonstrate momentum splitting up to 200 photon recoils in an ultra-cold atom interferometer. We highlight a new mechanism of destructive interference of the losses leading to a sizeable efficiency enhancement of the beam splitters. We perform a comprehensive study of parasitic interferometers due to the inherent multi-port feature of the quasi-Bragg pulses. Finally, we experimentally verify the phase shift enhancement and characterize the interferometer visibility loss.

Dichroic mirror pulses for optimized higher-order atomic Bragg diffraction [0.0]
We present the experimental realization of dichroic mirror pulses for atom interferometry specifically designed for higher-order Bragg diffraction. Our approach selectively reflects resonant atom paths into the detected interferometer output, ensuring that these contribute to the signal with intent. parasitic paths are efficiently transmitted by the mirror and not directed to the relevant interferometer outputs.

Robust Quantum Control via Multipath Interference for Thousandfold Phase Amplification in a Resonant Atom Interferometer [0.4941383238872373]
We introduce a novel technique for enhancing the robustness of light-pulse atom interferometers against the pulse infidelities that typically limit their sensitivities. We apply this method to a resonant atom interferometer and achieve thousand-fold phase amplification, representing a fifty-fold improvement over the performance observed without optimized control. We anticipate our findings will significantly benefit the performance of matter-wave interferometers for a variety of applications, including dark matter, dark energy, and gravitational wave detection.

Bragg-diffraction-induced imperfections of the signal in retroreflective atom interferometers [0.0]
Off-resonant higher-order diffraction leads to population loss, spurious interferometer paths, and diffraction phases. We compare first-order single and double Bragg diffraction in retroreflective setups. Some effects of diffraction phases can be avoided by adding the population of the outer exit ports of double diffraction.

Tuning the mode-splitting of a semiconductor microcavity with uniaxial stress [49.212762955720706]
In this work we use an open microcavity composed of a "bottom" semiconductor distributed Bragg reflector (DBR) incorporating an n-i-p heterostructure. We demonstrate a reversible in-situ technique to tune the mode-splitting by applying uniaxial stress to the semiconductor DBR. A thorough study of the mode-splitting and its tuning across the stop-band leads to a quantitative understanding of the mechanism behind the results.

We describe a technique to measure photon pair joint spectra by detecting the time-correlation beat note when non-degenerate photon pairs interfere at a beamsplitter. The technique is well suited to characterize pairs of photons, each of which can interact with a single atomic species.

We demonstrate that photon bunching and anti-bunching persist much longer than both radiative and non-radiative lifetimes of a single qubit.

Tailoring multi-loop atom interferometers with adjustable momentum transfer [0.0]
Multi-loop matter-wave interferometers are essential in quantum sensing to measure the derivatives of physical quantities in time or space. imperfections of the matter-wave mirrors create spurious paths that scramble the signal of interest. Here we demonstrate a method of adjustable momentum transfer that prevents the recombination of the spurious paths in a double-loop atom interferometer aimed at measuring rotation rates.
