Optimizing bias-tailored quantum error correction beyond code-capacity noise
César Benito, I. Jesán Velázquez-Reséndiz, Alejandro Bermudez
We find that the substantial advantages predicted for bias-tailored quantum error correction (QEC) under code-capacity noise are strongly reduced once realistic syndrome extraction…
Logical error estimation from syndrome data of surface-code experiments
Evangelia Takou, Cesar Benito, Arian Vezvaee +2
Decoders for quantum error correction (QEC) experiments rely on detector error models (DEMs), which encode, for each error, its probability and the detectors and logical observable…
Scaling roadmap for modular trapped-ion QEC and lattice-surgery teleportation
César Benito, Alfredo Ricci Vasquez, Jonathan Home +4
We present a footprint study for the scaling of modular quantum error correction (QEC) protocols designed for triangular color codes, including a lattice-surgery-based logical tele…
Surface code scaling on heavy-hex superconducting quantum processors
Arian Vezvaee, Cesar Benito, Mario Morford-Oberst +2
Demonstrating subthreshold scaling of a surface-code quantum memory on hardware whose native connectivity does not match the code remains a central challenge. We address this on IB…
Real-Time Dynamics in a (2+1)-D Gauge Theory: The Stringy Nature on a Superconducting Quantum Simulator
Jesús Cobos, Joana Fraxanet, César Benito +7
Understanding the confinement mechanism in gauge theories and the universality of effective string-like descriptions of gauge flux tubes remains a fundamental challenge in modern p…
Comparative study of quantum error correction strategies for the heavy-hexagonal lattice
César Benito, Esperanza López, Borja Peropadre +1
Topological quantum error correction is a milestone in the scaling roadmap of quantum computers, which targets circuits with trillions of gates that would allow running quantum alg…
