Quantum Cellular Automata on a Dual-Species Rydberg Processor
Ryan White, Vikram Ramesh, Alexander Impertro +6
As quantum devices scale to larger and larger sizes, a significant challenge emerges in scaling their coherent controls accordingly. Quantum cellular automata (QCAs) constitute a p…
Engineering discrete local dynamics in globally driven dual-species atom arrays
Francesco Cesa, Andrea Di Fini, David Aram Korbany +4
We introduce a method for engineering discrete local dynamics in globally-driven dual-species neutral atom experiments, allowing us to study emergent digital models through uniform…
High-fidelity entanglement and coherent multi-qubit mapping in an atom array
Aruku Senoo, Alexander Baumgärtner, Joanna W. Lis +5
Neutral atoms in optical tweezer arrays possess broad applicability for quantum information science, in computing, simulation, and metrology. Among atomic species, Ytterbium-171 is…
Adiabatic echo protocols for robust quantum many-body state preparation
Zhongda Zeng, Giuliano Giudici, Aruku Senoo +3
Entangled many-body states are a key resource for quantum technologies. Yet their preparation through analog control of interacting quantum systems is often hindered by experimenta…

Unraveling PXP Many-Body Scars through Floquet Dynamics
Giuliano Giudici, Federica Maria Surace, Hannes Pichler
Quantum scars are special eigenstates of many-body systems that evade thermalization. They were first discovered in the PXP model, a well-known effective description of Rydberg ato…
Quantum control of continuous systems via nonharmonic potential modulation
Piotr T. Grochowski, Hannes Pichler, Cindy A. Regal +1
We present a theoretical proposal for preparing and manipulating a state of a single continuous-variable degree of freedom confined to a nonharmonic potential. By utilizing optimal…
Variational manifolds for ground states and scarred dynamics of blockade-constrained spin models on two and three dimensional lattices
