Efficiently simulable quantum circuits with large entanglement, magic, and non-Gaussianity via code-compiled tensor networks
Aydin Deger, Stergios Koutsioumpas, Mark Webster +3
We introduce a family of quantum circuits that possess standard indicators of classical simulation hardness including high entanglement entropy, magic, and non-Gaussianity, yet adm…
Colour Codes Reach Surface Code Performance using Vibe Decoding
Stergios Koutsioumpas, Tamas Noszko, Hasan Sayginel +2
Two-dimensional quantum colour codes hold significant promise for quantum error correction, offering advantages such as planar connectivity and low overhead logical gates. Despite…
Fault-Tolerant Logical Clifford Gates from Code Automorphisms
Hasan Sayginel, Stergios Koutsioumpas, Mark Webster +2
We study the implementation of fault-tolerant logical Clifford gates on stabilizer quantum error correcting codes based on their symmetries. Our approach is to map the stabilizer c…
Automorphism Ensemble Decoding of Quantum LDPC Codes
Stergios Koutsioumpas, Hasan Sayginel, Mark Webster +1
We introduce AutDEC, a fast and accurate decoder for quantum error-correcting codes with large automorphism groups. Our decoder employs a set of automorphisms of the quantum code a…
