Non-local finite-depth circuits for constructing SPT states and quantum cellular automata
David T. Stephen, Arpit Dua, Ali Lavasani +1
Whether a given target state can be prepared by starting with a simple product state and acting with a finite-depth quantum circuit is a key question in condensed matter physics an…
Tailoring three-dimensional topological codes for biased noise
Eric Huang, Arthur Pesah, Christopher T. Chubb +2
Tailored topological stabilizer codes in two dimensions have been shown to exhibit high storage threshold error rates and improved subthreshold performance under biased Pauli noise…
Pauli topological subsystem codes from Abelian anyon theories
Tyler D. Ellison, Yu-An Chen, Arpit Dua +3
We construct Pauli topological subsystem codes characterized by arbitrary two-dimensional Abelian anyon theories--this includes anyon theories with degenerate braiding relations an…
Emergent fermionic gauge theory and foliated fracton order in the Chamon model
Wilbur Shirley, Xu Liu, Arpit Dua
The Chamon model is an exactly solvable spin Hamiltonian exhibiting nontrivial fracton order. In this work, we dissect two distinct aspects of the model. First, we show that it exh…
Fractionalization of subsystem symmetries in two dimensions
David T. Stephen, Arpit Dua, José Garre-Rubio +2
The fractionalization of global symmetry charges is a striking hallmark of topological quantum order. Here, we discuss the fractionalization of subsystem symmetries in two-dimensio…
Three-dimensional quantum cellular automata from chiral semion surface topological order and beyond
Wilbur Shirley, Yu-An Chen, Arpit Dua +3
We construct a novel three-dimensional quantum cellular automaton (QCA) based on a system with short-range entangled bulk and chiral semion boundary topological order. We argue tha…
