Phase-Stable Hologram Updates for Large-Scale Neutral-Atom Array Reconfiguration
Erdong Huang, Jiayi Huang, Hongshun Yao +2
Assembling large-scale, defect-free Rydberg atom arrays is a key technology for neutral-atom quantum computation. Dynamic holographic optical tweezers enable the assembly and recon…
Theory of the Collective Many-body Subradiance in Waveguide Quantum Electrodynamics
Xin Wang, Junjun He, Zeyang Liao
We present an analytical theory for the most subradiant modes in a finite one-dimensional emitter array coupled to either an ideal or a nonideal waveguide. Using an effective non-H…
Super-Heisenberg-limited Sensing via Collective Subradiance in Waveguide Quantum Electrodynamics
Xin Wang, Zeyang Liao
We explore the quantum-metrological potential of subwavelength-spaced emitter arrays coupled to a one-dimensional nanophotonic waveguide. In this system, strong dipole--dipole inte…
Tunable ultrahigh reflection with broadband via collective atom-atom interaction in waveguide-QED system
Xin Wang, Junjun He, Zeyang Liao +1
We present a scheme for achieving broadband complete reflection by constructing photonic bandgap via collective atom-atom interaction in a one-dimensional (1D) waveguide quantum el…
