Computing 256-bit elliptic curve discrete logarithms in 26 days on a fault-tolerant trapped-ion quantum computer with 20,000 qubits
Thomas Häner, Felix Tripier, Jacob Young +11
One of the strengths of our recently proposed Walking Cat Architecture for a trapped-ion quantum computer is that it is straightforward to extend and optimize for a specific applic…
Fast logical operations in quantum LDPC codes using simple resource states
Mark Webster, Nicolas Delfosse
Quantum LPDC codes provide a substantial reduction in qubit overhead required for fault-tolerant quantum computation compared to surface code, thanks to their high encoding rate. H…
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…
Fault-Tolerant Quantum Computing with Trapped Ions: The Walking Cat Architecture
Felix Tripier, Woo Chang Chung, Jacob Young +15
We propose a fault-tolerant quantum computer architecture for trapped-ion devices, which we call the walking cat architecture. Our blueprint includes a compiler, a detailed descrip…
Distance-Finding Algorithms for Quantum Codes and Circuits
Mark Webster, Abraham Jacob, Oscar Higgott
The distance of a classical or quantum code is a key figure of merit which reflects its capacity to detect errors. Quantum LDPC code families have considerable promise in reducing…
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…
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…
Heuristic and Optimal Synthesis of CNOT and Clifford Circuits
Mark Webster, Stergios Koutsioumpas, Dan E Browne
Efficiently implementing Clifford circuits is crucial for quantum error correction and quantum algorithms. Linear reversible circuits, equivalent to circuits composed of CNOT gates…
Low-overhead Magic State Circuits with Transversal CNOTs
Nicholas Fazio, Mark Webster, Zhenyu Cai
With the successful demonstration of transversal CNOTs in many recent experiments, it is the right moment to examine its implications on one of the most critical parts of fault-tol…
Engineering Quantum Error Correction Codes Using Evolutionary Algorithms
Mark Webster, Dan Browne
Quantum error correction and the use of quantum error correction codes is likely to be essential for the realisation of practical quantum computing. Because the error models of qua…
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…
