Non-Clifford quantum cellular automata from invertible topological quantum field theories
Meng Sun, Zongyuan Wang, Bowen Yang +2
Quantum cellular automata (QCAs) describe locality-preserving quantum dynamics and connect quantum information, many-body physics, and topological quantum field theory (TQFT). Cons…
Operator algebra and algorithmic construction of boundaries and defects in (2+1)D topological Pauli stabilizer codes
Zijian Liang, Bowen Yang, Joseph T. Iosue +1
Quantum low-density parity-check codes, such as the Kitaev toric code and bivariate bicycle codes, are often defined with periodic boundary conditions, which are difficult to reali…
Resolving spurious topological entanglement entropy in stabilizer codes
Peilun Han, Zijian Liang, Yifei Wang +3
Topological entanglement entropy (TEE) is a key diagnostic of long-range entanglement in two-dimensional gapped phases of matter, but it can suffer from spurious contributions that…
The Classification of Pauli Stabilizer Codes: A Lattice and Continuum Treatise
Bowen Yang, Matthew Yu
We classify mobile Pauli stabilizer codes up to gapped interfaces and coarse-graining using the framework of algebraic -theory. We compare this classification with that…
Clifford quantum cellular automata from topological quantum field theories and invertible subalgebras
Meng Sun, Bowen Yang, Zongyuan Wang +2
We present a general framework for constructing quantum cellular automata (QCA) from topological quantum field theories (TQFT) and invertible subalgebras (ISA) using the cup-produc…
