We experimentally performed adaptive phase estimation using time-symmetric quantum smoothing for a stochastically varying phase on continuous wave coherent beam. We demonstrate better accuracy than conventional methods.
S l MMARY \'hen applied to rapidly moving objects with complex t r a rectories. the information-rate limitation imposed by video-camera frame rates impairs the effectiveness of structured-light techniques in real-time robot servoing. To improve the performance of such systems. the use of fa.[ infra-red proximity detectors to augment vis dance in the final… (More)
We demonstrate squeezing-enhanced adaptive optical phase estimation for a stochastically varying phase. By using a continuous-wave phase squeezed beam, estimation accuracy is improved by a factor of 1.4 compared to a coherent beam case.
This report describes the accomplishments of the Nanomanufacturing of Atom-based Dimensional Standards Project, which operated as part of the National Advanced Manufacturing Testbed (NAMT), a program to research a wide range of leading edge technologies for manufacturing. As part of the NAMT vision, the Nanomanufacturing of Atom-based Dimensional Standards… (More)
