High-Magnetic-Field Rydberg Atom Interactions. [PDF]

, 2013
In this thesis I examine high-magnetic-field Rydberg spectra, with the goal of discerning the viability of using such states as an interaction mechanism for quantum computation processes.

Metasurface-Assisted Rydberg-Atom Sensor with Wavefront Shaping and Enhanced Sensitivity

Photonics
Rydberg-atom electric-field sensors have emerged as an important research direction in quantum precision measurement, owing to their intrinsic SI traceability, noninvasive measurement capability, and wide frequency tunability.

An Injection-locked Diode Laser for Cold Rydberg Atom Experiments

, 2007
A free-running, temperature stabilized diode laser has been injection-locked to an external cavity diode laser for use in cold Rydberg atom experiments. Cold rubidium atoms in a magneto-optical trap (MOT) are excited to Rydberg states using a 10 ns laser

Sub-shot-noise Rydberg EIT spectrum

PhotoniX
Atom-based sensing with optical readout is fundamentally limited by photon shot noise. Squeezed light can effectively suppress this noise of optical readout, thereby enabling measurement sensitivities beyond the standard quantum limit, but their ...

Coherent two photon excitation within an extended cloud of Rubidium 85 for the purposes of atomic interferometry and cooling

, 2011
Cold atom samples, at temperatures of the order 100 µK, are useful for a wide reaching array of new and exciting technological and scientific endeavours. Atoms are conventionally cooled by Doppler cooling, which relies on the continuous absorption and re-

Imaging Spatial Correlations of Rydberg Excitations in Cold Atom Clouds. [PDF]

, 2013
When cold atoms are laser-excited to Rydberg states, the strong interactions between Rydberg excitations can lead to complex many-body entanglement in the system. The excitation process results in spatial correlations between excitations in the system.

Cavity-enhanced Rydberg atom microwave receiver

Developing microwave electric field sensing based on Rydberg atom has received significant attention due to its unique advantages. However, achieving effective coupling between Rydberg atom and the microwave electric field in the sensing process is a ...

THE KINEMATICS OF RYDBERG ATOM - SULFUR HEXAFLUORIDE COLLISIONS

, 1984
Negative ions formed in the reaction A** + BC (--->) A('+) + BC('-) where A** is a highly-excited Rydberg atom and BC is an electron-attaching molecule exhibit very long lifetimes against autodetachment.
