Interferometry is a paradigm for most precision measurements. Using N uncorrelated
particles, the achievable precision for a two-mode (two-path) interferometer is bounded by …

Quantum Fourier transforms (QFTs) have gained increased attention with the rise of
quantum walks, boson sampling, and quantum metrology. Here, we present and …

Ultra-cold atoms provide ideal platforms for interferometry. The macroscopic matter-wave
property of ultra-cold atoms leads to large coherent length and long coherent time, which …

We design a multimode interferometer with cold atoms confined in a harmonic trap. A first
Kapitza-Dirac pulse creates several spatially addressable modes which are coherently …

xploiting quantum interference remains a significant challenge in ultracold inelastic
scattering. In this work, we propose a method to enable detectable quantum interference …

We propose a theoretical scheme for measuring a laser's wavelength. Within a one-
dimensional harmonic potential well, the laser wavelength forming Kapitza–Dirac pulses …

We present a new technique for improving the sensitivity of an interferometer, phase-shift-
amplified interferometry (PAI), which is based on two embedded interferometers. The …

We study the ultimate bounds on the sensitivity of a Bloch-oscillation atom interferometer
where the external force is estimated from the measurement of the on-site atomic density …

We realize a double-path multimode matter wave interferometer with spinor Bose-Einstein
condensate and observe clear spatial interference fringes as well as a periodic change of …

The dynamics of multimode interferometers for Bose Einstein condensation (BEC) with
atomic interactions confined to a harmonic trap is investigated. At the initial time t= 0, several …
