Programmable Fermionic Quantum Processors with Globally Controlled Lattices
Gabriele Calliari, Charles Fromonteil, Francesco Cesa +4
We introduce a framework for realizing universal fermionic quantum processing with globally controlled itinerant fermionic particles. Our approach is tailored to the example of neu…
Imaginary time evolution and ground state preparation using unitary multi-copy protocols
Tal Schwartzman, Torsten V. Zache, Hannes Pichler +1
Efficient low-energy state preparation is a key objective in quantum computation and quantum simulation. Quantum imaginary-time evolution replaces real-time dynamics with imaginary…
Field digitization scaling in a symmetric model
Gabriele Calliari, Robert Ott, Hannes Pichler +1
The simulation of quantum field theories, both classical and quantum, requires regularization of infinitely many degrees of freedom. However, in the context of field digitization (…
U(1) lattice gauge theory and string roughening on a triangular Rydberg array
Lisa Bombieri, Torsten V. Zache, Hannes Pichler +1
Lattice gauge theories (LGTs) describe fundamental interactions in particle physics. A central phenomenon in these theories is confinement, which binds quarks and antiquarks into h…
Rare-Event Quantum Sensing using Logical Qubits
Robert Ott, Torsten V. Zache, Soonwon Choi +2
We present a novel protocol to detect rare signals in a noisy environment using quantum error correction (QEC). The key feature of our protocol is the discrimination between signal…
Deconfined quantum criticality on a triangular Rydberg array
Lisa Bombieri, Torsten V. Zache, Gabriele Calliari +3
Fluctuations can drive continuous phase transitions between two distinct ordered phases -- so-called deconfined quantum critical points (DQCPs) -- which lie beyond the Landau-Ginzb…
