Characterizing Large Scale Quantum Systems with Error Per Circuit Layer
Travis Hurant, Arian Vezvaee, Swarnadeep Majumder +3
Quantum benchmarks provide compact measures of performance that are important for evaluating and comparing quantum systems. Circuit-level benchmarks are particularly valuable becau…
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…
Quantum Error Correction and Dynamical Decoupling: Better Together or Apart?
Victor Kasatkin, Mario Morford-Oberst, Arian Vezvaee +1
Quantum error correction/detection (QEC/QED) and dynamical decoupling (DD) are tools for protecting quantum information. A natural goal is to combine them to outperform either appr…
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…
