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…
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…
