Error-corrected Hadamard gate simulated at the circuit level
György P. Gehér, Campbell McLauchlan, Earl T. Campbell +2
We simulate the logical Hadamard gate in the surface code under a circuit-level noise model, compiling it to a physical circuit on square-grid connectivity hardware. Our paper is t…
Generalized quantum data-syndrome codes and belief propagation decoding for phenomenological noise
Kao-Yueh Kuo, Ching-Yi Lai
Quantum stabilizer codes often struggle with syndrome errors due to measurement imperfections. Typically, multiple rounds of syndrome extraction are employed to ensure reliable err…
A real-time, scalable, fast and highly resource efficient decoder for a quantum computer
Ben Barber, Kenton M. Barnes, Tomasz Bialas +10
To unleash the potential of quantum computers, noise effects on qubits' performance must be carefully managed. The decoders responsible for diagnosing noise-induced computational e…
Tangling schedules eases hardware connectivity requirements for quantum error correction
Gyorgy P. Geher, Ophelia Crawford, Earl T. Campbell
Quantum computers have the potential to change the way we solve computational problems. Due to the noisy nature of qubits, the need arises to correct physical errors occurring duri…
Nanocavity enhanced photon coherence of solid-state quantum emitters operating up to 30 K
Alistair J. Brash, Jake Iles-Smith
Solid-state emitters such as epitaxial quantum dots have emerged as a leading platform for efficient, on-demand sources of indistinguishable photons, a key resource for many optica…
Transversal Diagonal Logical Operators for Stabiliser Codes
Mark A. Webster, Armanda O. Quintavalle, Stephen D. Bartlett
Storing quantum information in a quantum error correction code can protect it from errors, but the ability to transform the stored quantum information in a fault tolerant way is eq…
