Interorbital Interactions in an SU(2)xSU(6)-Symmetric Fermi-Fermi Mixture
Benjamin Abeln, Koen Sponselee, Marcel Diem +3
We characterize inter- and intraisotope interorbital interactions between atoms in the 1S0 ground state and the 3P0 metastable state in interacting Fermi-Fermi mixtures of 171Yb an…
Quantum Gate Optimization for Rydberg Architectures in the Weak-Coupling Limit
Nicolas Heimann, Lukas Broers, Nejira Pintul +5
We demonstrate machine learning assisted design of a two-qubit gate in a Rydberg tweezer system. Two low-energy hyperfine states in each of the atoms represent the logical qubit an…
Dynamics of Ultracold Quantum Gases in the Dissipative Fermi-Hubbard Model
Koen Sponselee, Lukas Freystatzky, Benjamin Abeln +8
We employ metastable ultracold Yb atoms to study dynamics in the 1D dissipative Fermi-Hubbard model experimentally and theoretically, and observe a complete inhibition of t…
Humanity's Last Exam
Long Phan, Alice Gatti, Ziwen Han +1144
Benchmarks are important tools for tracking the rapid advancements in large language model (LLM) capabilities. However, benchmarks are not keeping pace in difficulty: LLMs now achi…
