Universal Quantum Computation with Gapped Boundaries
Iris Cong, Meng Cheng, Zhenghan Wang
This Letter discusses topological quantum computation with gapped boundaries of two-dimensional topological phases. Systematic methods are presented to encode quantum information t…

Hamiltonian and Algebraic Theories of Gapped Boundaries in Topological Phases of Matter
Iris Cong, Meng Cheng, Zhenghan Wang
We present an exactly solvable lattice Hamiltonian to realize gapped boundaries of Kitaev's quantum double models for Dijkgraaf-Witten theories. We classify the elementary excitati…

Microscopic Theory of Surface Topological Order for Topological Crystalline Superconductors
Meng Cheng
We construct microscopic Hamiltonians for symmetry-preserving topologically ordered states on the surface of topological crystalline superconductors, protected by a …
