Efficient biphoton generation by a waveguide-coupled single atom
Mao-Hua Wang, Xiao-Jun Zhang, M. Artoni +2
A single atom undergoing spontaneous four-wave mixing near a chiral waveguide can efficiently channel an emitted Stokes-anti-Stokes photon pair into two tightly confined waveguide…
Laguna M.1/XS.2 Technical Report
Julien Abadji, Marah Abdin, Connor Adams +93
We present Laguna M.1 and Laguna XS.2, two Mixture-of-Experts foundation models built for long-horizon, agentic coding: M.1 has B total parameters (B activated per tok…
Enhancing ground-state interaction strength of neutral atoms via Floquet stroboscopic dynamics
Y. Wei, M. Artoni, G. C. La Rocca +2
Neutral atom systems are promising platforms for quantum simulation and computation, owing to their long coherence times. However, their intrinsically weak ground-state interaction…
Non-Hermitian optical scattering in cold atoms via four-wave mixing
Xiao Liu, M. Artoni, G. C. La Rocca +1
Nonlinear effects could play a crucial role in addressing optical nonreciprocal behaviors in scattering media. Such behaviors are, however, typically observed within a single trans…
Single-photon manipulations based on optically-controlled chiral couplings in waveguide structures of Rydberg giant atoms
Yao-Tong Chen, Lei Du, Zhihai Wang +3
Two interacting Rydberg atoms coupled to a waveguide realize a giant-atom platform that exhibits the controllable (phase-dependent) chirality where the direction of nonreciprocal p…
Giant-Atom Effects on Population and Entanglement Dynamics of Rydberg Atoms
Yao-Tong Chen, Lei Du, Yan Zhang +4
Giant atoms are attracting interest as an emerging paradigm in the quantum optics of engineered waveguides. Here we propose to realize a synthetic giant atom working in the optical…
