Timo Hillmann
Postdoctoral Researcher @ University of Sydney, Australia
I am a researcher working in the field of quantum information. My research focusses on the theory of quantum error correction with bosonic codes, typically with a focus on concepts relevant to near-term devices. My projects so far range from the development of architectures for bosonic codes realized in superconducting circuits as well as in optical systems, to the development of new error correction protocols and decoders with a focus on the utilization of analog information.
I completed my PhD at Chalmers University of Technology, Sweden, where I worked on theoretical aspects of quantum error correction for near-term quantum devices.

| Oct 30, 2025 | I’ve recently joined the University of Sydney as a Postdoctoral Researcher in the group of Stephen Bartlett, Andrew Doherty, and Dominic Williamson. Excited to continue exploring quantum error correction and related topics alongside an incredible team of researchers, postdocs, and students. |

| Feb 28, 2025 | Since the beginning of my second year as a PhD student (now I only have a couple of months left), I’ve been consulting with Xanadu, contributing to various areas of the architecture, such as state preparation, measurement-based quantum computing, and quantum error correction. It’s been fascinating to see these contributions take shape over time, and it’s even more exciting to witness how much progress has been made since then. The recent Nature paper Scaling and networking a modular photonic quantum computer combines many of the team’s efforts over the past years, presenting all the experimental subsystems necessary to implement universal and fault-tolerant quantum computation in a photonic architecture. |
| Oct 18, 2024 | Last year I spent a couple of months as a visitin researcher at Xanadu in Toronto. I wanted to use that time to finally properly understand fault-tolerant MBQC. Digging in the literature I found that previous works didn’t fit my style of thinking. We ended up recasting foliation in terms of the hypergraph product, enabling us to use the machinery of homology to analyse foliated codes. This proved to be very useful for understanding single-shot error correction in mbqc and also for understanding stability experiments in higher-dimensional topological codes and their implications for lattice surgery.
