Abstract

We report progress toward the development of a chip-based cold atom trap based on nanoscale waveguides, which incorporates a fabricated two-wire magnetic trap to assist in transferring laser-cooled atoms to the waveguides.

An atom chip for the manipulation of ultracold atoms

Owen Cherry, J. D. Carter, J. D. D. Martin

We have fabricated an atom chip that magnetically traps laser cooled 87Rb by generating high magnetic-field gradients using micrometre scale current-carrying wires. The wires are fabricated on a Si wafer (with a 40 nm SiO2 layer) using 1.2 μm thick Au and a 20 nm thick adhesion layer, and are patterned with lift-off photolithography. We characterize the number and temperature of the cold atoms trapped by the chip.

Cold atom and nanophotonics hybrid platform

Hikaru Tamura, Xinchao Zhou, Tzu-Han Chang +1 more

Interfacing cold atoms with nanoscale photonic structures promises stronger atom-light interactions and novel quantum functionalities via dispersion engineering, controlled photon propagation, topology, and chiral quantum transport. Recent years have seen advances in a number of atom-nanophotonics platforms with suspended nanostructures. However, extending such a system to planar structures faces immediate challenges due to reduced trap loading and laser cooling efficiency directly on a dielectric plane. In this talk, we will show experimental demonstration of precision guiding and trapping cold atoms in the near field of a planar nanophotonic circuit, and realization of large atom-photon coupling to a whispering-gallery mode in a microring resonator.

A new type of atom-photon interface

Nathan Cooper, David Johnson, Daniele Baldolini +3 more

Hybrid quantum devices, incorporating both atoms and photons, are able to exploit the benefits of both systems. Compact, robust atom-photon interfaces will enable scalable architectures for quantum computing and quantum communication, as well as chip-scale sensors and single-photon sources. We demonstrate a new type of interface and show the interaction of cold cesium atoms with resonant photons. For this atoms are cooled in a magneto-optical trap, transferred to an optical dipole trap and positioned inside a transverse, 30 µm diameter through-hole in an optical fibre, created via laser micromachining. The intersection is orthogonal to the propagation direction of the light mode. We trap about 300 atoms at a temperature of 120µK. When the guided light is on resonance with the caesium D2 line, up to 87% of it is absorbed by the atoms. Our technique can be applied in 2-dimensional systems, i.e. in optical waveguide chips and other existing photonic systems. We also discuss the influence of hole shapes on transmission and prospects of adding a micro-cavity.

Advances in chip-scale cold atom photonic technologies

Xiaofei Yang, Haixu Tao, Ning Wei +4 more

Laser-cooled atoms are a key quantum medium for atomic clocks, precision metrology, and atom interferometers, and they hold strong potential to advance quantum technologies for position, navigation, and timing. Realizing this potential requires moving cold-atom systems beyond laboratory environments. Integrated photonic chips provide a path forward by improving reliability and reducing size, weight, and power consumption, enabling portable and compact quantum sensors for real-world applications. This review surveys recent progress in laser-cooled atomic platforms, with a focus on the key components that enable on-chip integration of cold-atom systems. We discuss on-chip laser stabilization and linewidth-narrowing techniques, enhanced photon–atom coupling at the chip scale, miniaturized high-vacuum chambers, and the integration of on-chip magnetic coils for cold-atom sensing. Together, these developments are critical to the deployment of chip-scale cold-atom devices in both fundamental atomic physics and practical sensing applications. We conclude with an outlook on next-generation integrated cold-atom platforms and their potential impact on quantum technologies.

Interaction between atoms and slow light: a waveguide-design study

Xiaorun Zang, Jianji Yang, Rémi Faggiani +8 more

The emerging field of on-chip integration of nanophotonic devices and cold atoms offers extremely-strong and pure light-matter interaction schemes, which may have profound impact on quantum information science. In this context, a long-standing obstacle is to achieve strong interaction between single atoms and single photons, while at the same time trap atoms in vacuum at large separation distances from dielectric surfaces. In this work, we study new waveguide geometries that challenge these conflicting objectives. The designed photonic crystal waveguide is expected to offer a good compromise, which additionally allows for easy manipulation of atomic clouds around the structure, while being tolerant to fabrication imperfections.
