Abelian multi-cycle codes for single-shot error correction
Hsiang-Ku Lin, Pak Kau Lim, Alexey A. Kovalev +1
We construct a family of quantum low-density parity-check codes locally equivalent to higher-dimensional quantum hypergraph-product (QHP) codes. Similarly to QHP codes, the propose…
Topological orders with classical Lie group symmetries from coupling electron wires
Pak Kau Lim, Michael Mulligan, Jeffrey C. Y. Teo
We study the topological order that arises from chiral states with or edge-state symmetry. This extends our previous study of topological orders that de…
Partial fillings of the bosonic quantum Hall state
Pak Kau Lim, Michael Mulligan, Jeffrey C. Y. Teo
We study bosonic topological phases constructed from electrons. In addition to a bulk excitation energy gap, these bosonic phases also have a fermion energy gap, below which all lo…
Disentangling (2+1)d Topological States of Matter with the Entanglement Negativity
Pak Kau Lim, Hamed Asasi, Jeffrey C. Y. Teo +1
We use the entanglement negativity, a bipartite measure of entanglement in mixed quantum states, to study how multipartite entanglement constrains the real-space structure of the g…
Topological defects in general quantum LDPC codes
Pak Kau Lim, Kirill Shtengel, Leonid P. Pryadko
We consider the structure of defects carrying quantum information in general quantum low-density parity-check (LDPC) codes. These generalize the corresponding constructions for top…
