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…
Addressable gate-based logical computation with quantum LDPC codes
Laura Pecorari, Francesco Paolo Guerci, Hugo Perrin +1
Quantum computing relies on quantum error correction for high-fidelity logical operations, but scaling to achieve near-term quantum utility is highly resource-intensive. High-rate…
Fast Quantum Gates for Neutral Atoms Separated by a Few Tens of Micrometers
Matteo Bergonzoni, Rosario Roberto Riso, Guido Pupillo
We present a theoretical scheme for a family of fast and high-fidelity two-qubit iSWAP gates between neutral atoms separated by more than 20 um, enabled by resonant dipole-dipole s…
Low-depth quantum error correction via three-qubit gates in Rydberg atom arrays
Laura Pecorari, Sven Jandura, Guido Pupillo
Quantum error correction (QEC) requires the execution of deep quantum circuits with large numbers of physical qubits to protect information against errors. Designing protocols that…
Cavity polariton blockade for non-local entangling gates with trapped atoms
Vineesha Srivastava, Sven Jandura, Gavin K. Brennen +1
We propose a scheme for realizing multi-qubit entangled W-state and non-local and gates via a cavity polariton blockade mechanism with a system of atomic qubits coupled…
