Agents' Last Exam
Yiyou Sun, Xinyang Han, Weichen Zhang +306
Recent AI systems have achieved strong results on a wide range of benchmarks, yet these gains have not translated into economically meaningful deployment across many professional d…
Programmable spectral symmetries in an anisotropic quantum Rabi simulator
Jia-Cheng Song, Yu Liu, Ming-Chuan Wang +28
The quantum Rabi model captures fundamental aspects of light--matter interaction, where symmetry dictates both spectra and dynamics. Over the past years, experiments have explored…
Dissipation-Selected Resonant Fronts in a Driven-Dissipative Bose-Hubbard Lattice
Wei-Guo Ma, Heng Fan
Spatially structured dissipation organizes driven quantum matter beyond Hamiltonian control. We show that a dissipation gradient combined with a Stark-induced detuning ramp selects…
Logarithmic light cone, slow entanglement growth, and quantum memory
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +4
Effective light cones, characterized by Lieb-Robinson bounds, emerge in nonrelativistic local quantum systems. Here, we present several analytical results derived from logarithmic…
Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor
Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24
Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
