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…
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…
