Topological quantum color code model on infinite lattice
Shiyu Cao, Zhian Jia, Sheng Tan
The color code model is a crucial instance of a Calderbank--Shor--Steane (CSS)-type topological quantum error-correcting code, which notably supports transversal implementation of…

Antilinear superoperator, quantum geometric invariance, and antilinear symmetry for higher-dimensional quantum systems
Lu Wei, Zhian Jia, Dagomir Kaszlikowski +1
We present a systematic investigation of antilinear superoperators and their applications in studying open quantum systems, particularly focusing on quantum geometric invariance, e…

Electric-magnetic duality and symmetry enriched Abelian lattice gauge theory
Zhian Jia, Dagomir Kaszlikowski, Sheng Tan
Kitaev's quantum double model is a lattice gauge theoretic realization of Dijkgraaf-Witten topological quantum field theory (TQFT), its topologically protected ground state space h…
