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…
Large Matrix Quantum Mechanics as a Quantum Memory
ChunJun Cao, Gong Cheng, Brian Swingle
In this paper, we explore the possibility of building a quantum memory that is robust to thermal noise using large matrix quantum mechanics models. First, we investigate the ga…
Conformal field theories are magical
Christopher David White, ChunJun Cao, Brian Swingle
"Magic" is the degree to which a state cannot be approximated by Clifford gates. We study mana, a measure of magic, in the ground state of the Potts model, and argue…
