QMCtwin: Master-Equation Simulation of Syndrome Statistics Beyond Pauli Noise
Tong Shen, Huo Chen, Benchen Huang +4
As quantum error correction moves toward large-scale experimental implementations, decoder performance increasingly depends on how faithfully hardware noise is translated into synd…
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…
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…
Demonstration of High-Fidelity Entangled Logical Qubits using Transmons
Arian Vezvaee, Vinay Tripathi, Mario Morford-Oberst +3
Quantum error correction (QEC) codes are necessary to fault-tolerantly operate quantum computers. However, every such code is inherently limited by its inability to detect logical…
