Minimum Weight Decoding in the Colour Code is NP-hard
Mark Walters, Mark L. Turner
All utility-scale quantum computers will require some form of Quantum Error Correction in which logical qubits are encoded in a larger number of physical qubits. One promising enco…
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…
Scalable decoding protocols for fast transversal logic in the surface code
Mark L. Turner, Earl T. Campbell, Ophelia Crawford +2
Atomic, molecular and optical (AMO) approaches to quantum computing are promising due to their increased connectivity, long coherence times and apparent scalability. However, they…
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…
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…
