Macromux: scalable postselection for high-threshold fault-tolerant quantum computation
Patrick Birchall, Jacob Bridgeman, Christopher Dawson +7
We introduce a new resource-efficient scheme for fault-tolerant quantum computation known as `macroscale multiplexing' (or simply `Macromux'), that utilizes scalable postselection…
Lifting topological codes: Three-dimensional subsystem codes from two-dimensional anyon models
Jacob C. Bridgeman, Aleksander Kubica, Michael Vasmer
Topological subsystem codes in three spatial dimensions allow for quantum error correction with no time overhead, even in the presence of measurement noise. The physical origins of…
Boundary topological entanglement entropy in two and three dimensions
Jacob C. Bridgeman, Benjamin J. Brown, Samuel J. Elman
The topological entanglement entropy is used to measure long-range quantum correlations in the ground state of topological phases. Here we obtain closed form expressions for topolo…
Gauging Defects in Quantum Spin Systems
Jacob C. Bridgeman, Alexander Hahn, Tobias J. Osborne +1
The goal of this work is to build a dynamical theory of defects for quantum spin systems. A kinematic theory for an indefinite number of defects is first introduced exploiting dist…
Computing data for Levin-Wen with defects
Jacob C. Bridgeman, Daniel Barter
We demonstrate how to do many computations for non-chiral topological phases with defects. These defects may be 1-dimensional domain walls or 0-dimensional point defects. Using $\o…
Tensor Networks with a Twist: Anyon-permuting domain walls and defects in PEPS
Jacob C. Bridgeman, Stephen D. Bartlett, Andrew C. Doherty
We study the realization of anyon-permuting symmetries of topological phases on the lattice using tensor networks. Working on the virtual level of a projected entangled pair state,…
Anomalies and entanglement renormalization
Jacob C. Bridgeman, Dominic J. Williamson
We study 't Hooft anomalies of discrete groups in the framework of (1+1)-dimensional multiscale entanglement renormalization ansatz states on the lattice. Using matrix product oper…
Hand-waving and Interpretive Dance: An Introductory Course on Tensor Networks
Jacob C. Bridgeman, Christopher T. Chubb
The curse of dimensionality associated with the Hilbert space of spin systems provides a significant obstruction to the study of condensed matter systems. Tensor networks have prov…
