New QEC paper out π Our tile codes are a new and simple approach to construct local codes on a 2D planar lattice. Read more here if you're interested: scirate.com/arxiv/2504.0...
Submissions for QEC 2025 are now open through March 28.
This will easily be the most exciting conference on quantum error correction yet!

When I first heard about quantum error correction I thought it was the most boring subject in the world. It turns out to be one of the most interesting subjects in the world. My judgment isnβt always that great. βοΈ
Many thanks to my fantastic collaborators Benedikt Placke, Tibor Rakovszky and Vedika Khemani! :)
5/5 Our results build on a new quantum bottleneck theorem (scirate.com/arxiv/2412.0...) establishing when energy barriers lead to stable quantum memories, opening new directions connecting quantum phases of matter with quantum computation!
4/5 The phase has remarkable properties: Not just ground states but even finite energy density states can encode and preserve quantum information. This leads to an emergent hierarchy of quantum memories.
3/5 We prove this phase exists in concrete physical systems - Hamiltonians derived from quantum LDPC codes that have certain expansion properties. These are local Hamiltonians that exhibit "linear confinement."
2/5 TQSG order is characterized by the shattering of the Gibbs state into exponentially many components. Unlike classical spin glasses, each component here preserves quantum information!
1/5 Excited to share our latest work where we introduce a new phase of matter - the Topological Quantum Spin Glass (TQSG). It combines features of spin glass order and topological order in a fundamentally new way.
