All-optical universal control of nuclear-spin qudits in trapped neutral atoms
Johannes K. Krondorfer, Matthias Diez, Andreas Kruckenhauser +1
Quantum systems with more than two levels - so-called qudits - offer increased computational density and reduced circuit complexity compared to qubit-based architectures, but achie…
Ground-state reachability for variational quantum eigensolvers: a Rydberg-atom case study
Juhi Singh, Andreas Kruckenhauser, Rick van Bijnen +1
As quantum computing progresses, variational quantum eigensolvers (VQE) for ground-state preparation have become an attractive option in leveraging current quantum hardware. Howeve…
Dark spin-cats as biased qubits
Andreas Kruckenhauser, Ming Yuan, Han Zheng +8
We present a biased atomic qubit, universally implementable across all atomic platforms, encoded as a `spin-cat' within ground state Zeeman levels. The key characteristic of our co…
High-dimensional SO(4)-symmetric Rydberg manifolds for quantum simulation
Andreas Kruckenhauser, Rick van Bijnen, Torsten V. Zache +2
We develop a toolbox for manipulating arrays of Rydberg atoms prepared in high-dimensional hydrogen-like manifolds in the regime of linear Stark and Zeeman effect. We exploit the S…
Realizing distance-selective interactions in a Rydberg-dressed atom array
Simon Hollerith, Kritsana Srakaew, David Wei +10
Measurement-based quantum computing relies on the rapid creation of large-scale entanglement in a register of stable qubits. Atomic arrays are well suited to store quantum informat…
Topological phonons in arrays of ultracold dipolar particles
Marco Di Liberto, Andreas Kruckenhauser, Peter Zoller +1
The notion of topology in physical systems is associated with the existence of a nonlocal ordering that is insensitive to a large class of perturbations. This brings robustness to…
Quantum optimization via four-body Rydberg gates
Clemens Dlaska, Kilian Ender, Glen Bigan Mbeng +3
There is a large ongoing research effort towards obtaining a quantum advantage in the solution of combinatorial optimization problems on near-term quantum devices. A particularly p…
Quantum Many-Body Physics with Ultracold Polar Molecules: Nanostructured Potential Barriers and Interactions
Andreas Kruckenhauser, Lukas M. Sieberer, William G. Tobias +8
We design dipolar quantum many-body Hamiltonians that will facilitate the realization of exotic quantum phases under current experimental conditions achieved for polar molecules. T…
Dynamical Equilibration of Topological Properties
Andreas Kruckenhauser, Jan Carl Budich
We study the dynamical process of equilibration of topological properties in quantum many-body systems undergoing a parameter quench between two topologically inequivalent Hamilton…
