Error-corrected fermionic quantum processors with neutral atoms
Robert Ott, Daniel González-Cuadra, Torsten V. Zache +3
Many-body fermionic systems can be simulated in a hardware-efficient manner using a fermionic quantum processor. Neutral atoms trapped in optical potentials can realize such proces…
Quantum simulating continuum field theories with large-spin lattice models
Gabriele Calliari, Marco Di Liberto, Hannes Pichler +1
Simulating the real-time dynamics of quantum field theories (QFTs) is one of the most promising applications of quantum simulators. Regularizing a bosonic QFT for quantum simulatio…
Observation of string breaking on a (2 + 1)D Rydberg quantum simulator
Daniel Gonzalez-Cuadra, Majd Hamdan, Torsten V. Zache +10
Lattice gauge theories (LGTs) describe a broad range of phenomena in condensed matter and particle physics. A prominent example is confinement, responsible for bounding quarks insi…
Probing topological entanglement on large scales
Robert Ott, Torsten V. Zache, Nishad Maskara +3
Topologically ordered quantum matter exhibits intriguing long-range patterns of entanglement, which reveal themselves in subsystem entropies. However, measuring such entropies, whi…
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…
Entanglement Structure of Non-Gaussian States and How to Measure It
Henry Froland, Torsten V. Zache, Robert Ott +1
Rapidly growing capabilities of quantum simulators to probe quantum many-body phenomena require new methods to characterize increasingly complex states. We present a protocol that…
Hamiltonian Learning in Quantum Field Theories
Robert Ott, Torsten V. Zache, Maximilian Prüfer +5
We discuss Hamiltonian learning in quantum field theories as a protocol for systematically extracting the operator content and coupling constants of effective field theory Hamilton…
