New QEC paper out 🙂 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 isn’t always that great. ⚛️

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.
