Local Clustering Decoder as a fast and adaptive hardware decoder for the surface code
Abbas B. Ziad, Ankit Zalawadiya, Canberk Topal +4
To avoid prohibitive overheads in performing fault-tolerant quantum computation, the decoding problem needs to be solved accurately and at speeds sufficient for fast feedback. Exis…
Demonstrating real-time and low-latency quantum error correction with superconducting qubits
Laura Caune, Luka Skoric, Nick S. Blunt +22
Quantum error correction (QEC) will be essential to achieve the accuracy needed for quantum computers to realise their full potential. The field has seen promising progress with de…
Leakage Mobility in Superconducting Qubits as a Leakage Reduction Unit
Joan Camps, Ophelia Crawford, György P. Gehér +3
Leakage from the computational subspace is a damaging source of noise that degrades the performance of most qubit types. Unlike other types of noise, leakage cannot be overcome by…
Accommodating Fabrication Defects on Floquet Codes with Minimal Hardware Requirements
Campbell McLauchlan, György P. Gehér, Alexandra E. Moylett
Floquet codes are an intriguing generalisation of stabiliser and subsystem codes, which can provide good fault-tolerant characteristics while benefiting from reduced connectivity r…
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…
