Diagnosing and Restoring the Degraded Fault Distance of Magic State Cultivation

Tim Chan, Armands Strikis, Zhu Sun +1

T-state cultivation is a resource-efficient protocol producing logical T states but recent benchmarks show that its logical error rate is considerably higher than intended i.e. tha…

Stream Decoding with Confidence Scores at Room and Cryogenic Temperatures

Maries Tahaab, Tim Chan, James Kirkman +1

In fault-tolerant quantum computing, fast and accurate decoding is crucial. Snowflake is a decoder for the surface code that runs in a streaming fashion. In this paper, we implemen…

Error mitigation for logical circuits using decoder confidence

Maria Dincă, Tim Chan, Simon C. Benjamin

Fault-tolerant quantum computers use decoders to monitor for errors and find a plausible correction. A decoder may provide a \emph{decoder confidence score} (DCS) to gauge its succ…

An Entanglement Monotone from the Contextual Fraction

Tim Chan, Andrei Constantin

The contextual fraction introduced by Abramsky and Brandenburger defines a quantitative measure of contextuality associated with empirical models, i.e. tables of probabilities of m…

Actis: A Strictly Local Union-Find Decoder

Tim Chan, Simon C. Benjamin

Fault-tolerant quantum computing requires classical hardware to perform the decoding necessary for error correction. The Union-Find decoder is one of the best candidates for this.…
