Controversy surrounds the measurement of tunneling times in strong-field ionization, with differing results from the attoclock and Larmor clock methods. Here, the authors reinterpret the attoclock as a weak value of temporal delay, deriving a position-resolved tunneling time that reconciles these discrepancies and enhances understanding of non-local time measurements.

Stable, ultra-low-noise integrated lasers are essential for scalable quantum computers and portable optical clocks. Here, authors demonstrate a chip-scale coil stabilized Brillion laser driving a room-temperature trapped-ion clock and qubit without a bulk reference cavity achieving 99.6% SPAM fidelity.

Momentum-entangled atom pairs are used to demonstrate quantum non-locality, where changing one atom in an entangled pair instantly alters the state of the other atom. This result paves the way to study interactions between quantum states and gravity.

A cavity-array microscope is realized using intra-cavity lenses to create a two-dimensional array of over 40 modes, each coupled to a single atom in free-space.

We design and demonstrate a variety of integrated-photonics-based polarization-gradient-cooling systems, culminating in the first experimental demonstration of trapped-ion polarization-gradient cooling using integrated photonics, facilitating new capabilities for integrated-photonics-based trapped-ion platforms.

Many-body dipole-dipole interactions constitute the basis of numerous physical phenomena in atom vapor. Here, the authors demonstrate a triple-quantum dual-comb two-dimensional coherent spectroscopy to investigate the dipole-dipole interactions, finding that the triple-quantum correlations (0.95) surpass the double-quantum counterparts (0.90).

By combining an ultralow-loss silicon nitride reference cavity with a diode laser, the interrogation of a strontium-ion optical clock is possible with excellent accuracy. The development is a step towards miniature, integrated optical clocks.

Interacting emitters are the fundamental building blocks of quantum optics and quantum information devices. Pairs of organic molecules embedded in a crystal can become permanently strongly interacting when they are pumped with intense laser light.

Ultracold atoms provide a platform for realizing the temporal analogue of Snell’s law.

With atom-light couplings in atomic systems, scientists have demonstrated several iconic lattice models that exhibit non-trivial band topology in controlled manners, which expands our capability to investigate exotic topological matter.
