Local Clifford equivalence to CSS codes: Polynomial-time classification and conversion
Mingyuan Wang, Stefan Krastanov
Calderbank--Shor--Steane (CSS) codes support decoding and fault-tolerant logical operations through separate pure and pure stabilizer checks. Generator choices and single-q…

Efficient Graph State Purification with Factorized Graph-Preserving Operations across Local Clifford Orbits
Mingyuan Wang, Guus Avis, Kenneth Goodenough +1
Graph states form a broad class of multipartite entangled states underlying measurement-based quantum computation, quantum networks, and stabilizer codes. However, systematic entan…

GHZ-Preserving Gates and Optimized Distillation Circuits
Mingyuan Wang, Guus Avis, Stefan Krastanov
Greenberger-Horne-Zeilinger (GHZ) states play a central role in quantum computing and communication protocols, as a typical multipartite entanglement resource. This work introduces…
