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…
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 (…
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…
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…
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…
