Geometry-optimized hyperbolic codes for modular fault-tolerant quantum architectures
Ahmed Adel Mahmoud, Steven Rayan
Quantum fault tolerance is a prerequisite to harness the full potential of quantum computers. However, achieving fault tolerance remains a major challenge since it requires optimiz…
A diagrammatic field theory of quantum error correction
Steven Rayan
We develop a field-theoretic framework for quantum error correction centred on fusion-space codes in unitary fusion categories. Admissible clusters determine total-charge sectors a…
Quantum Entanglement, Stratified Spaces, and Topological Matter: Towards Entanglement-Sensitive Langlands Data
Kazuki Ikeda, Steven Rayan
Using the spinless Haldane model, we study the witness-filtered Berry curvature, quantum geometric tensor, and quantum Fisher information on the gapped strata of the parameter spac…
TQFTs and quantum computing
Mahmud Azam, Steven Rayan
Quantum computing is captured in the formalism of the monoidal subcategory of generated by -- in particular, quantum circuits are diagrams…
