Error-detected surgery on Iceberg codes
Andrea Di Fini, Samuel Crew, Laura Pecorari +1
We construct explicit error-detecting surgery gadgets---small systems of auxiliary qubits and checks---for the high-rate Iceberg codes , to perform fault-detected me…
Fault-tolerant quantum computation with static atomic buses
Matteo Bergonzoni, Laura Pecorari, Sam Norrell +3
Efficient quantum error correction and fault-tolerant quantum computing require scalable, high-fidelity long-range connectivity. In neutral-atom quantum computers, this is commonly…
Enhanced localization length in a disordered one-dimensional band via cavity coupling to delocalized states
Francesco Mattiotti, Guido Pupillo, Jérôme Dubail +1
We investigate the localization properties of cavity-coupled electronic states in disordered systems, motivated by recent proposals of cavity-mediated hopping in quantum Hall syste…
Pontryagin Maximum Principle for Rydberg-blockaded state-to-state transfers: A semi-analytic approach
Federico Alberto Astolfi, Sven Jandura, Guido Pupillo
We study time-optimal state-to-state control for two- and multi-qubit operations motivated by neutral-atom quantum processors within the Rydberg blockade regime. Block-diagonalizat…
Correlated Atom Loss as a Resource for Quantum Error Correction
Hugo Perrin, Gatien Roger, Guido Pupillo
Atom loss is a dominant error source in neutral-atom quantum processors, yet its correlated structure remains largely unexploited by existing quantum error correction decoders. We…
Loss-biased fault-tolerant quantum error correction
Laura Pecorari, Gavin K. Brennen, Stanimir S. Kondov +1
We investigate the limits of quantum error correction (QEC) in neutral-atom processors approaching high-fidelity gates and fast cycle times. We show that shorter QEC cycles amplify…
