Ramsey Interference with Single Photons.
- PhysicsPhysical review letters
- 2016
This work experimentally generates energy superposition states of a single photon and manipulates them with unitary transformations to realize arbitrary projective measurements and opens the path for frequency-encoded photonic qubits in quantum information processing and quantum communication.
Cold atom space clock with counter-propagating atoms
- Physics
- 2009
We discuss the feasibility of realizing a cold atom space clock with counter-propagating cold atoms in microgravity. The design of the space clock is based on an atomic beam clock with Ramsey cavity,…

Electron spin relaxation, important in quantum information science, can be slowed down at clock transitions — which are insensitive to magnetic noise. It has now been shown that such transitions can…
SU(2) hyper-clocks: Quantum engineering of spinor interferences for time and frequency metrology
- PhysicsPhysical Review Research

In 1949, Ramsey’s method of separated oscillating fields was elaborated boosting over many decades metrological performances of atomic clocks and becoming the standard technique for very high…
Planar-Integrated Magneto-Optical Trap

The magneto-optical trap (MOT) is an essential tool for collecting and preparing cold atoms with a wide range of applications. We demonstrate a planar-integrated MOT by combining an optical grating…
Adsorption of cesium from waste desalination brine through Dowex G26 resin and comparison with t-BAMBP/kerosene and t-BAMBP/C2mimNTf2 systems

SPECTRAL LINES AS FREQUENCY STANDARDS
- PhysicsAnnals of the New York Academy of Sciences
- 1952
Although the problems involved in the design of accurate and reliable frequency and time standards are somewhat different, these two topics will be dealt with together since a clock can be used as a frequencyStandard while a frequency standard by itself will not read time.
World-wide Frequency and Time Comparisons by Means of Radio Transmissions
- PhysicsNature
