Quantum Lego Expansion Pack: Enumerators from Tensor Networks
ChunJun Cao, Michael J. Gullans, Brad Lackey +1
We provide the first tensor network method for computing quantum weight enumerator polynomials in the most general form. If a quantum code has a known tensor network construction o…
Superselection Rules, Quantum Error Correction, and Quantum Chromodynamics
Ning Bao, ChunJun Cao, Aidan Chatwin-Davies +2
We investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflam…
Discovery of Optimal Quantum Error Correcting Codes via Reinforcement Learning
Vincent Paul Su, ChunJun Cao, Hong-Ye Hu +3
The recently introduced Quantum Lego framework provides a powerful method for generating complex quantum error correcting codes (QECCs) out of simple ones. We gamify this process a…
Non-trivial Area Operators Require Non-local Magic
ChunJun Cao
We show that no stabilizer codes over any local dimension can support a non-trivial area operator for any bipartition of the physical degrees of freedom even if certain code subalg…
Overlapping qubits from non-isometric maps and de Sitter tensor networks
ChunJun Cao, Wissam Chemissany, Alexander Jahn +1
We construct approximately local observables, or "overlapping qubits", using non-isometric maps and show that processes in local effective theories can be spoofed with a quantum sy…
