Integrating an Atom Array with a Nanophotonic Chip: A Scalable Quantum System [PDF]

Neutral atom arrays have been established as a leading platform in the quantum information science landscape, due in large part to their scalability and reconfigurable, any-to-any connectivity. Similarly, neutral atoms coupled to optical cavities have shown promise for quantum networking due to the inherent indistinguishability of individual atoms.

System-level integration of a chip-scale atomic clock: microwave oscillator and physics package

2006 Multiconference on Electronics and Photonics, 2006
We report on our progress in developing a prototype chip-scale atomic clock and describe the integration of the local oscillator and the physics package. A discussion of the design and results is given with a focus on frequency stability, size, and power consumption. Finally, we suggest methods to improve reliability.

Atom Interferometry on Atom Chips-A Novel Approach Towards Precision Inertial Navigation Systems (PINS)

2008
Abstract : Considerable progress was made during the grant period toward establishing a chip based atom interferometer. At the beginning of the gBECi period, no coherent on-chip beam splitter had been demonstrated. During the funding period, we developed two area enclosing interferometers with demonstrated coherence preservation: one using optical ...

Chip Scale Atomic Resonator Frequency Stabilization System With Ultra-Low Power Consumption for Optoelectronic Oscillators

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016
We present a long-term chip scale stabilization scheme for optoelectronic oscillators (OEOs) based on a rubidium coherent population trapping (CPT) atomic resonator. By locking a single mode of an OEO to the (85)Rb 3.035-GHz CPT resonance utilizing an improved phase-locked loop (PLL) with a PID regulator, we achieved a chip scale frequency ...

Atomic Force Microscopy Imaging and Electrical Recording of Lipid Bilayers Supported over Microfabricated Silicon Chip Nanopores:  Lab-on-a-Chip System for Lipid Membranes and Ion Channels

Langmuir, 2006
We describe a silicon chip-based supported bilayer system to detect the presence of ion channels and their electrical conductance in lipid bilayers. Nanopores were produced in microfabricated silicon membranes by electron beam lithography as well as by using a finely focused ion beam.

Development of a new hybrid technique for rapid speciation analysis by directly interfacing a microfluidic chip‐based capillary electrophoresis system to atomic fluorescence spectrometry

ELECTROPHORESIS, 2005
AbstractThis paper represents the first study on direct interfacing of microfluidic chip‐based capillary electrophoresis (chip‐CE) to a sensitive and selective detector, atomic fluorescence spectrometry (AFS) for rapid speciation analysis. A volatile species generation technique was employed to convert the analytes from the chip‐CE effluent into their ...
