Creating topological exceptional point by on-chip all-dielectric metasurface [PDF]
Classified as a non-Hermitian system, topological metasurface is one of the ideal platforms for exploring a striking property, that is, the exceptional point (EP).

Spectral properties of two superconducting artificial atoms coupled to a resonator in the ultrastrong coupling regime [PDF]
We 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 ...

Collection of fluorescence from an ion using trap-integrated photonics [PDF]
Spontaneously emitted photons are entangled with the electronic and nuclear degrees of freedom of the emitting atom, so interference and measurement of these photons can entangle separate matter-based quantum systems as a resource for quantum information

Programmable system on chip for controlling an atomic physics experiment [PDF]
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 ...

A flexible system-on-a-chip control hardware for atomic, molecular, and optical physics experiments [PDF]
We have implemented a control system core for experiments in atomic, molecular, and optical physics based on a commercial low-cost board, featuring a field-programmable gate array as part of a system-on-a-chip on which a Linux operating system is running.

Mechanisms for the emergence of Gaussian correlations
We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system undergoing out-of-equilibrium dynamics.

Integrated DFB Lasers on Si3N4 Photonic Platform for Chip-Scale Atomic Systems [PDF]
780 nm wavelength distributed feedback lasers have been integrated onto a Si3N4 photonic platform on a Si substrate and coupled into waveguides for laser locking to either a ring resonator or rubidium vacuum cell.

Photonic integrated beam delivery for a rubidium 3D magneto-optical trap
Cold atoms are important for precision atomic applications including timekeeping and sensing. The 3D magneto-optical trap (3D-MOT), used to produce cold atoms, will benefit from photonic integration to improve reliability and reduce size, weight, and ...

Research on a chip scale atomic clock driven GNSS/SINS deeply coupled navigation system for augmented performance [PDF]
Chip scale atomic clock (CSAC) is a recently developed low‐profile atomic frequency reference device. Researchers have demonstrated CSAC was able to improve the accuracy of Global navigation satellite system (GNSS) receiver positioning results. However, the work was conducted using scalar tracking loops (STL).
