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…

Quantum rotation sensor with real-time readout based on an atom-cavity system

Jim Skulte, Jayson G. Cosme, Ludwig Mathey

Using an atom-cavity platform, we propose to combine the effective gauge phase of rotated neutral atoms and the superradiant phase transition to build a highly sensitive and fast q…

Bridging closed and dissipative discrete time crystals in spin systems with infinite-range interactions

Jayson G. Cosme, Jim Skulte, Ludwig Mathey

We elucidate the role that the dissipation in a bosonic channel plays in the prevalence and stability of time crystals (TCs) in a periodically driven spin-boson system described by…

Dissipative time crystal in an atom-cavity system: Influence of trap and competing interactions

Richelle Jade L. Tuquero, Jim Skulte, Ludwig Mathey +1

While the recently realized dissipative time crystal in a laser-pumped atom-cavity system in the experiment of Keßler et al. [Phys. Rev. Lett. 127, 043602 (2021)] is qualitatively…

Mitigated barren plateaus in the time-nonlocal optimization of analog quantum-algorithm protocols

Lukas Broers, Ludwig Mathey

Quantum machine learning has emerged as a promising utilization of near-term quantum computation devices. However, algorithmic classes such as variational quantum algorithms have b…

Emergent limit cycles and time crystal dynamics in an atom-cavity system

Hans Keßler, Jayson G. Cosme, Michal Hemmerling +2

We propose an experimental realization of a time crystal using an atomic Bose-Einstein condensate in a high finesse optical cavity pumped with laser light detuned to the blue side…
