Quantum-amplified global-phase spectroscopy on an optical clock transition
Leon Zaporski, Qi Liu, Gustavo Velez +5
Optical lattice clocks (OLCs) are at the forefront of precision metrology, operating near a standard quantum limit (SQL) set by quantum noise. Harnessing quantum entanglement offer…
Bose-Einstein condensation by polarization gradient laser cooling
Wenchao Xu, Tamara Šumarac, Emily H. Qiu +7
Attempts to create quantum degenerate gases without evaporative cooling have been pursued since the early days of laser cooling, with the consensus that polarization gradient cooli…
Increased Atom-Cavity Coupling through Cooling-Induced Atomic Reorganization
Chi Shu, Simone Colombo, Zeyang Li +4
The strong coupling of atoms to optical cavities can improve optical lattice clocks as the cavity enables metrologically useful collective atomic entanglement and high-fidelity mea…
Improving Metrology with Quantum Scrambling
Zeyang Li, Simone Colombo, Chi Shu +7
Quantum scrambling describes the spreading of local information into many degrees of freedom in quantum systems. This provides the conceptual connection among diverse phenomena ran…
Extreme Spin Squeezing via Optimized One-Axis Twisting and Rotations
Sebastian C. Carrasco, Michael H. Goerz, Zeyang Li +3
We propose a novel scheme for the generation of optimal squeezed states for Ramsey interferometry. The scheme consists of an alternating series of one-axis twisting pulses and rota…
Collective Spin-Light and Light-Mediated Spin-Spin Interactions in an Optical Cavity
Zeyang Li, Boris Braverman, Simone Colombo +6
The interaction between an atomic ensemble and a light mode in a high-finesse optical cavity can easily reach the strong-coupling regime, where quantum effects dominate. In this re…
Time-Reversal-Based Quantum Metrology with Many-Body Entangled States
Simone Colombo, Edwin Pedrozo-Peñafiel, Albert F. Adiyatullin +4
In quantum metrology, entanglement represents a valuable resource that can be used to overcome the Standard Quantum Limit (SQL) that bounds the precision of sensors that operate wi…
Entanglement-Enhanced Optical Atomic Clock
Edwin Pedrozo-Peñafiel, Simone Colombo, Chi Shu +8
State-of-the-art atomic clocks are based on the precise detection of the energy difference between two atomic levels, measured as a quantum phase accumulated in a given time interv…
Trapping Yb Atoms into a One-Dimensional Optical Lattice with a Small Waist
Akio Kawasaki, Boris Braverman, Edwin Pedrozo-Peñafiel +4
In most experiments with atoms trapped in optical lattices, the transverse size of the optical lattice beams is on the order of tens of micrometers, and loading many atoms into sma…
Near-Unitary Spin Squeezing in Yb
Boris Braverman, Akio Kawasaki, Edwin Pedrozo-Peñafiel +9
Spin squeezing can improve atomic precision measurements beyond the standard quantum limit (SQL), and unitary spin squeezing is essential for improving atomic clocks. We report sub…
Comparing many-body localization lengths via non-perturbative construction of local integrals of motion
Pai Peng, Zeyang Li, Haoxiong Yan +2
Many-body localization (MBL), characterized by the absence of thermalization and the violation of conventional thermodynamics, has elicited much interest both as a fundamental phys…
Geometrically asymmetric optical cavity for strong atom-photon coupling
Akio Kawasaki, Boris Braverman, Edwin Pedrozo-Peñafiel +11
Optical cavities are widely used to enhance the interaction between atoms and light. Typical designs using a geometrically symmetric structure in the near-concentric regime face a…
Scalable Quantum Tomography with Fidelity Estimation
Jun Wang, Zhao-Yu Han, Song-Bo Wang +4
We propose a quantum tomography scheme for pure qudit systems which adopts random base measurements and generative learning methods, along with a built-in fidelity estimation appro…
Statistics of Chaotic Resonances in an Optical Microcavity
Li Wang, Domenico Lippolis, Ze-Yang Li +3
Distributions of eigenmodes are widely concerned in both bounded and open systems. In the realm of chaos, counting resonances can characterize the underlying dynamics (regular vs.…
