This Letter discusses topological quantum computation with gapped boundaries of two-dimensional topological phases. Systematic methods are presented to encode quantum information topologically using gapped boundaries, and to perform topologically protected operations on this encoding. In particular, we introduce a new and general computational primitive of topological charge measurement and present a symmetry-protected implementation of this primitive. Throughout the Letter, a concrete physical…

Mathematics of Topological Quantum Computing

In topological quantum computing, information is encoded in "knotted" quantum states of topological phases of matter, thus being locked into topology to prevent decay. Topological precision has been

The boundaries and twist defects of the color code and their applications to topological quantum computation

This work builds upon the abstract theory of boundaries and domain walls of topological phases of matter to comprehensively catalog the objects realizable in color codes and provides lattice representations of these objects which include three new types of boundaries as well as a generating set for all 72 color code twist defects.

Electric-magnetic duality of $\mathbb{Z}_2$ symmetry enriched cyclic Abelian lattice gauge theory

Kitaev’s quantum double model is a lattice gauge theoretic realization of Dijkgraaf-Witten topological quantum field theory (TQFT), its topologically protected ground state space has broad

Numerical investigation of gapped edge states in fractional quantum Hall-superconductor heterostructures

Fractional quantum Hall-superconductor heterostructures may provide a platform towards non-abelian topological modes beyond Majoranas. However their quantitative theoretical study remains extremely

Fault-tolerant quantum gates with defects in topological stabilizer codes

This work presents an approach to implement the full Clifford group via braiding in any code possessing twist defects on which a fermion can condense, and shows how the no-go theorems can be circumvented to provide a universal scheme in three-dimensional surface codes without magic state distillation.

Tunneling Topological Vacua via Extended Operators: (Spin-)TQFT Spectra and Boundary Deconfinement in Various Dimensions

Distinct quantum vacua of topologically ordered states can be tunneled into each other via extended operators. The possible applications include condensed matter and quantum cosmology. We present a

Measuring the Unique Identifiers of Topological Order Based on Boundary-Bulk Duality and Anyon Condensation

A topological order is a new quantum phase that is beyond Landau's symmetry-breaking paradigm. Its defining features include robust degenerate ground states, long-range entanglement and anyons. It

Prediction of Toric Code Topological Order from Rydberg Blockade

The physical realization of $\mathbb Z_2$ topological order as encountered in the paradigmatic toric code has proven to be an elusive goal. We show that this phase of matter can be created in a

Beyond anyons

The theory of anyon systems, as modular functors topologically and unitary modular tensor categories algebraically, is mature. To go beyond anyons, our first step is the interplay of anyons with



Topological Quantum Computation with Gapped Boundaries

This paper studies fault-tolerant quantum computation with gapped boundaries. We first introduce gapped boundaries of Kitaev's quantum double models for Dijkgraaf-Witten theories using their

Quantum computation

The theory of quantum computation can be constructed from the abstract study of anyonic systems. In mathematical terms, these are unitary topological modular functors. They underlie the Jones

Surface codes: Towards practical large-scale quantum computation

The concept of the stabilizer, using two qubits, is introduced, and the single-qubit Hadamard, S and T operators are described, completing the set of required gates for a universal quantum computer.

Universal quantum computation with weakly integral anyons

This work analyzes the computational power of the first non-abelian anyon system with only integral quantum dimensions and sets up three qutrit computational models, finding a universal gate set for each model.

String-net condensation: A physical mechanism for topological phases

We show that quantum systems of extended objects naturally give rise to a large class of exotic phases---namely topological phases. These phases occur when extended objects, called ``string-nets,''

Charge 2e/3 Superconductivity and Topological Degeneracies without Localized Zero Modes in Bilayer Fractional Quantum Hall States.

It is demonstrated that an analog of non-Abelian braiding is possible, despite the absence of a localized zero mode, and the superconductor induces charge 2e/3 quasiparticle-pair condensation at each boundary of the FQH state.

The Quantum Double Model with Boundary: Condensations and Symmetries

Associated to every finite group, Kitaev has defined the quantum double model for every orientable surface without boundary. In this paper, we define boundaries for this model and characterize

Symmetry fractionalization, defects, and gauging of topological phases

We examine the interplay of symmetry and topological order in $2+1$ dimensional topological phases of matter. We present a definition of the topological symmetry group, which characterizes the
