"Atomic phase measurements beyond the standard quantum limit"
Abstract: At NIST in Boulder, a long-standing goal of the atomic ions group has been to develop techniques for increasing spectroscopic sensitivity and apply these techniques to make better clocks. One avenue for improvement is to employ entangled states such as “spin-squeezed” states or “spin-Schroedinger-cat” states. We are able to generate states that show sensitivity beyond the standard quantum limit but we must also make better oscillators to take advantage of these techniques. We are also developing alternative methods for detection; these include application of simple quantum mapping operations and “quantum-non-demolition” or QND detection.
