The core ideas behind the signal-rule are also flexible, allowing for optimized variants or extensions to higher dimensions or other particles types. (5/6)
It 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)
Turns 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)
Universal 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)
Local decoder for the toric code with a high pseudo-threshold, happy to share that my first single-author paper is now available on the arXiv ! 👀 (1/6)
Our 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)
We 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)
Turns out you actually only need a few bits per qubit to decode the quantum repetition code in 1D with good performance ! We propose the signal-rule decoder, that interpret odd parities as defects attracted by each other, through the exchange of point-like signals. (3/6)
Universal 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)
High-performance local automaton decoder for defect matching in 1D, happy to share that our new work in with Anthony Leverrier, Mazyar Mirrahimi and @christophe.vuillot.info is now available on the arXiv ! 👀 (1/6)
First realization of a dissipatively stabilized squeezed cat qubit (a slight variation that we called a moon cat 🌛 actually), it was super interesting to work on this with experimentalists!
