Matter-wave phase measurement: A noninterferometric approach

Abstract

We show that noninterferometric techniques can produce quantitative phase measurements of quantum-mechanical wave fields with coherence requirements that are considerably reduced over those for interferometry.

Multiple pulse excitation of a designed Rydberg wave packet and noninterferometric quantum measurement

John A. Yeazell

Summary form only given. Design and excitation of novel quantum states and the measurement of those states is driven by both fundamental and technological goals. For example, the study of Schrodinger cat states touches upon the basic measurement hypotheses of quantum mechanics while the establishment of particular coherent superposition states is the starting point for the process of coherent control or for quantum information applications. The goals of the design research range from the manipulation of reaction pathways to the creation of novel states for the exploration of aspects of measurement theory. In addition to its fundamental interest the accurate measurement of both amplitude and phase of a wave function plays a key roles in the area of coherent control. The seminal work by Risken and Vogel (1989) reopened the modern discussion of the reconstruction problem that was first broached by Pauli. Since their work, reconstruction techniques have been developed for a variety of systems including the optical field in atomic systems. The measurement scheme used in the paper employs a noninterferometric technique. The subject of the measurement is a designed Rydberg wave packet in an atomic system. However, the noninterferometric character of the technique suggests that this technique may have wide applicability.

Neutron Phase Imaging and Tomography

Franz Pfeiffer, C. Grünzweig, Oliver Bunk +3 more

We report how a setup consisting of three gratings yields quantitative two- and three-dimensional images depicting the quantum-mechanical phase shifts of neutron de Broglie wave packets induced by the influence of macroscopic objects. Since our approach requires only a little spatial and chromatic coherence it provides a more than 2 orders of magnitude higher efficiency than existing techniques. This dramatically reduces the required measurement time for computed phase tomography and opens up the way for three-dimensional investigations of previously inaccessible quantum-mechanical phase interactions of neutrons with matter.

Noninterferometric phase imaging of a neutral atomic beam

Phillip J. Fox, Tracy R. Mackin, Lincoln D. Turner +3 more

We demonstrate quantitative phase imaging of a neutral atomic beam by using a noninterferometric technique. A collimated thermal atomic beam is phase shifted by an off-resonant traveling laser beam with both a Gaussian and a TEM01 profile and with both red and blue detuning of as much as 50 GHz. Phase variations of more than 1000 rad were recovered from velocity-selective measurements of the propagation of the atomic beam and were found to be in quantitative agreement with theoretical predictions based on independently measured phase object intensity profiles and detunings.
