Rydberg-atom-based system for benchmarking millimeter-wave automotive radar chips [PDF]
Physical Review AppliedRydberg atomic sensors and receivers have enabled sensitive and traceable measurements of rf fields at a wide range of frequencies. Here, we demonstrate the detection of electric field amplitude in the extremely-high-frequency (EHF) band, at 131GHz. In our approach, we propagate the EHF field in a beam, with control over its direction and polarization ...

Miniaturized optical system for a chip based cold atom inertial sensor
Applied OpticsWe miniaturized the complex optical system responsible for the cooling, pumping, and imaging of an on-chip-based cold-atom inertial sensor. This optical bench uses bonded miniature optics and includes all the necessary optical functions. The bench has a volume of 35×25×5cm3.

A misaligned magneto-optical trap to enable miniaturized atom chip systems [PDF]
Scientific Reports, 2018 AbstractWe describe the application of displaced, or misaligned, beams in a mirror-based magneto-optical trap (MOT) to enable portable and miniaturized atom chip experiments where optical access is limited to a single window. Two different geometries of beam displacement are investigated: a variation on the well-known ‘vortex-MOT’, and the other a ...

Atom chips with two-dimensional electron gases: Theory of near-surface trapping and ultracold-atom microscopy of quantum electronic systems [PDF]
Physical Review A, 2011 We show that current in a two-dimensional electron gas (2DEG) can trap ultracold atoms $<1 $m away with orders of magnitude less spatial noise than a metal trapping wire. This enables the creation of hybrid systems, which integrate ultracold atoms with quantum electronic devices to give extreme sensitivity and control: for example, activating a ...

Spectral properties of two superconducting artificial atoms coupled to a resonator in the ultrastrong coupling regime [PDF]
Nature CommunicationsWe experimentally investigate a superconducting circuit composed of two flux qubits ultrastrongly coupled to a common L C resonator. Owing to the large anharmonicity of the flux qubits, the system can be described well by a generalized Dicke Hamiltonian ...

A superconducting on-chip microwave cavity for tunable hybrid systems with optically trapped Rydberg atoms [PDF]
Hybrid quantum systems are highly promising platforms for addressing important challenges of quantum information science and quantum sensing. Their implementation, however, is technologically non-trivial, since each component typically has unique experimental requirements.

Programmable system on chip for controlling an atomic physics experiment [PDF]
Review of Scientific Instruments, 2021 Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment by providing triggers and clocks. Recently, the availability of well-documented open-source development tools has lifted the barriers to using programmable systems on chip (PSoCs), making them a convenient and versatile tool for synthesizing ...
