Erasure conversion in Majorana qubits via local quasiparticle detection Open
Quasiparticle poisoning errors in Majorana-based qubits are not suppressed by the underlying topological properties, which undermines the usefulness of this proposed platform. This work tackles the errors originating from intrinsically exc…

Symmetry-protected topological order as a requirement for measurement-based quantum gate teleportation Open
All known resource states for measurement-based quantum teleportation in correlation space possess symmetry-protected topological order, but is this a sufficient or even necessary condition? This work considers two families of one-dimensio…

The matrix permanent and determinant from a spin system Open
In contrast to the determinant, no algorithm is known for the exact determination of the permanent of a square matrix that runs in time polynomial in its dimension. Consequently, non interacting fermions are classically efficiently simulat…

Topological graph states and quantum error-correction codes Open
Deciding if a given family of quantum states is topologically ordered is an\nimportant but nontrivial problem in condensed matter physics and quantum\ninformation theory. We derive necessary and sufficient conditions for a family\nof graph…

Graph-state representation of the toric code Open
Given their potential for fault-tolerant operations, topological quantum states are currently the focus of intense activity. Of particular interest are topological quantum error correction codes, such as the surface and planar stabilizer c…

Generating and detecting topological phases with higher Chern number Open
Topological phases with broken time-reversal symmetry and Chern number |C|>=2 are of fundamental interest, but it remains unclear how to engineer the desired topological Hamiltonian within the paradigm of spin-orbit-coupled particles hoppi…

Quantum circuit for toric code state preparation via graph states Open
Given the wide applicability of topological states for fault-tolerant quantum computation, an important outstanding question is how to generate these states within the quantum circuit model, and if it is possible to do so efficiently. In t…

Detecting Topological Transitions in Two Dimensions by Hamiltonian Evolution Open
We show that the evolution of two-component particles governed by a two-dimensional spin-orbit lattice Hamiltonian can reveal transitions between topological phases. A kink in the mean width of the particle distribution signals the closing…
