Excited to share our new framework on combining QEM and QEC with 1. QEM applied directly to physical qubits 2. NO changes needed to the QEC layer 3. Applicable to most QEM methods & any QEC code Check out how this simple strategy leads to substantial improvement for small codes: shorturl.at/dJbgE

Can you correct both X and Z quantum noise using only a bit-flip classical codes? The answer is a surprising YES, using only ONE additional qubit and some post-processing! Check out our new work to see how: scirate.com/arxiv/2510.0...

The deadline is less than 10 days, please share with anyone that you think might be interested.

Our research group is seeking a talented and motivated Postdoctoral Researcher to join us in advancing the practical realisation of quantum technologies (including quantum error correction and mitigation). The deadline is 06 October 2025: tinyurl.com/bdhf3hzt

I am excited to receive the EPSRC Quantum Technology Fellowship hosted in Oxford. I will start a new research group focusing on a full-stack approach to quantum error suppression, including combining error mitigation and correction. More updates soon. tinyurl.com/ywp5zpun

The shortest theoretical possible pulse time in quantum optimal control is usually not the optimal pulse time in practice due to drift fields, limitations in optimisation and noise. In this paper, we show a way to construct pulses with optimal time in practical settings. scirate.com/arxiv/2504.0...

Ever thought QEM is only good for expectation value estimation & irrelevant for things like phase estimation? We prove otherwise by constructing an efficient way to apply QEM to any sampling algorithms, turning QEM into an indispensable tool for the early fault-tolerant era. tinyurl.com/4u9vv4hc

New paper out: scirate.com/arxiv/2501.1... By leveraging transversal CNOTs, we have constructed new fault-tolerant circuits for CCZ, CS, and T-state preparation, achieving minimal T depth alongside significantly reduced CNOT depth and qubit counts compared to before.

In scirate.com/arxiv/2412.1..., we look into the practical implementation of surface code without distillation using the sliding surface code scheme (Sci. Adv. 6, eaay4929). We realise that connectivity is not an issue in a 2D device if equipped with local short-range shuttling.

New paper: Presents a simple mapping from non-Markovian noise to quantum channels, enabling one to directly import conventional noise suppression techniques. Hopefully, this can be a bridge connecting between non-Markovian and Markovian noise suppression. scirate.com/arxiv/2412.1...
