Error correction on an array of superconducting qubits with defective components
Julien M. Drouet, Xanda C. Kolesnikow, Campbell K. McLauchlan +6
A solid-state quantum-computing architecture will require the fabrication of arrays of many coupled qubits. It is inevitable that this process will produce qubits and couplers with…
Scalable quantum error correction tailored for a heavy-hex qubit array
Seok-Hyung Lee, Xanda C. Kolesnikow, Jun Zen +7
To produce an operable quantum computer that is made with imperfect hardware, we must design and test scalable quantum error correcting codes that are suited for the devices we can…
Low-valency scalable quantum error correction with a dynamic compass code
Jun Zen, Xanda C. Kolesnikow, Campbell K. McLauchlan +6
The ongoing development of hardware that is capable of reliably executing general quantum algorithms requires quantum error-correcting codes that are both practical for realisation…
Efficient Post-Selection for General Quantum LDPC Codes
Seok-Hyung Lee, Lucas H. English, Stephen D. Bartlett
Post-selection strategies that discard low-confidence computational results can significantly improve the effective fidelity of quantum error correction at the cost of reduced acce…
Enhancing Decoding Performance using Efficient Error Learning
Pavithran Iyer, Aditya Jain, Stephen D. Bartlett +1
Lowering the resource overhead needed to achieve fault-tolerant quantum computation is crucial to building scalable quantum computers. We show that adapting conventional maximum li…
Characterising the failure mechanisms of error-corrected quantum logic gates
Robin Harper, Constance Lainé, Evan Hockings +4
Mid-circuit measurements used in quantum error correction are essential in quantum computer architecture, as they read out syndrome data and drive logic gates. Here, we use a heavy…
Characterizing physical and logical errors in a transversal CNOT via cycle error reconstruction
Nicholas Fazio, Robert Freund, Debankan Sannamoth +7
The development of prototype quantum information processors has progressed to a stage where small instances of logical qubit systems perform better than the best of their physical…
Low-overhead magic state distillation with color codes
Seok-Hyung Lee, Felix Thomsen, Nicholas Fazio +2
Fault-tolerant implementation of non-Clifford gates is a major challenge for achieving universal fault-tolerant quantum computing with quantum error-correcting codes. Magic state d…
Mitigating errors in logical qubits
Samuel C. Smith, Benjamin J. Brown, Stephen D. Bartlett
Quantum error correcting codes protect quantum information, allowing for large quantum computations provided that physical error rates are sufficiently low. We combine post-selecti…
Color code decoder with improved scaling for correcting circuit-level noise
Seok-Hyung Lee, Andrew Li, Stephen D. Bartlett
Two-dimensional color codes are a promising candidate for fault-tolerant quantum computing, as they have high encoding rates, transversal implementation of logical Clifford gates,…
Logical Noise Bias in Magic State Injection
Nicholas Fazio, Robin Harper, Stephen D. Bartlett
Fault-tolerant architectures aim to reduce the noise of a quantum computation. Despite such architectures being well studied a detailed understanding of how noise is transformed in…
Non-exponential Fidelity Decay in Randomized Benchmarking with Low-Frequency Noise
M. A. Fogarty, M. Veldhorst, R. Harper +4
We show that non-exponential fidelity decays in randomized benchmarking experiments on quantum dot qubits are consistent with numerical simulations that incorporate low-frequency n…
