Louis Paletta @louispaletta.bsky.social · 10/03/2026The core ideas behind the signal-rule are also flexible, allowing for optimized variants or extensions to higher dimensions or other particles types. (5/6) 100
Louis Paletta @louispaletta.bsky.social · 10/03/2026It is numerically shown that the decoder works well in the online regime, that is to say with data and measurement errors between each application of the local transition rule. (4/6) 100
Louis Paletta @louispaletta.bsky.social · 10/03/2026Turns out you actually only need a few bits per qubit to decode the toric code in 2D with good performance ! The paper introduces the 2D signal-rule decoder, that interprets odd parities as defects attracted by each other, through the exchange of point-like signals. (3/6) 100
Louis Paletta @louispaletta.bsky.social · 10/03/2026Universal fault-tolerant quantum computation demands real-time error correction—with major hardware constraints and the need for fast, efficient decoders. We consider an alternative architecture, where decoding is performed locally by uniform application of a simple transition rule. (2/6) 100

Louis Paletta @louispaletta.bsky.social · 16/05/2025Our decoders work naturally with biased-noise qubits, like cat qubits, enabling fully local 1D quantum memories. The core ideas behind the signal-rule are also flexible, allowing for optimized variants or possible future extensions to surface code decoding. (5/6) 100
Louis Paletta @louispaletta.bsky.social · 16/05/2025We also propose a variant on two rows of qubits to eliminate the need for any local classical memories, making it an appealing short-term solution. (4/6) 100
