A Traceable High-Accuracy Velocity Measurement by Electro-Optic Dual-Comb Interferometry
Applied Sciences, 2019 An electro-optic dual-comb Doppler velocimeter for high-accuracy velocity measurement is presented in this paper. The velocity information of the object can be accurately extracted from the change of repetition frequency, which is in the microwave ...

Berry-phase gates for fast and robust control of atomic clock states
Physical Review Research, 2020 We propose and experimentally demonstrate a fast Berry-phase gate, which is implemented by picosecond-timescale optical pulses to make the qubit system of atomic clock states adiabatically evolve on a closed loop.

Compact and frequency stabilized laser heads for Rubidium atomic clocks [PDF]
International Conference on Space Optics — ICSO 2012, 2017 We present the development and complete spectral characterization of our compact and frequency-stabilized laser heads, to be used for rubidium atomic clocks and basic spectroscopy. The light source is a Distributed Feed-Back (DFB) laser diode emitting at 780 nm or 795 nm.

Optical pumping and readout of bismuth hyperfine states in silicon for atomic clock applications [PDF]
, 2015 The push for a semiconductor-based quantum information technology has renewed interest in the spin states and optical transitions of shallow donors in silicon, including the donor bound exciton transitions in the near-infrared and the Rydberg, or ...

The ac stark shift and space-borne rubidium atomic clocks [PDF]
Journal of Applied Physics, 2016 Due to its small size, low weight, and low power consumption, the Rb atomic frequency standard (RAFS) is routinely the first choice for atomic timekeeping in space. Consequently, though the device has very good frequency stability (rivaling passive hydrogen masers), there is interest in uncovering the fundamental processes limiting its long-term ...

Algorithm for Taming Rubidium Atomic Clocks Based on Longwave (Loran-C) Timing Signals
Remote SensingThis paper explores effective methods for taming rubidium atomic clocks with longwave timing signals. In an in-depth analysis of the time-difference data between the 1PPS timing signal output from the ground-wave signal received by a long-wave receiver ...

Realisation of a cold mixture of rubidium and caesium [PDF]
, 2008 This thesis describes a new apparatus designed to study cold, ultracold, and quantum degenerate mixtures of rubidium and caesium atoms. The Rb- Cs mixture is prepared using a double magneto-optical trap (MOT) system in which a two-species pyramid MOT ...
