String Diagrams for Defect-Based Surface Code Computing
Mateusz Kupper, Dominic Horsman, Chris Heunen +1
Surface codes are a popular choice for implementing fault-tolerant quantum computing. Two-qubit gates may be realised in these codes using only nearest-neighbour interactions, eith…
Simple qudit ZX and ZH calculi, via integrals
Niel de Beaudrap, Richard D. P. East
The ZX calculus and ZH calculus use diagrams to denote and compute properties of quantum operations, using `rewrite rules' to transform between diagrams which denote the same opera…
Fast Stabiliser Simulation with Quadratic Form Expansions
Niel de Beaudrap, Steven Herbert
This paper builds on the idea of simulating stabiliser circuits through transformations of quadratic form expansions. This is a representation of a quantum state which specifies a…
Techniques to Reduce -Parity-Phase Circuits, Motivated by the ZX Calculus
Niel de Beaudrap, Xiaoning Bian, Quanlong Wang
To approximate arbitrary unitary transformations on one or more qubits, one must perform transformations which are outside of the Clifford group. The gate most commonly considered…
Quantum linear network coding for entanglement distribution in restricted architectures
Niel de Beaudrap, Steven Herbert
In this paper we propose a technique for distributing entanglement in architectures in which interactions between pairs of qubits are constrained to a fixed network . This allow…
On exact counting and quasi-quantum complexity
Niel de Beaudrap
We present characterisations of "exact" gap-definable classes, in terms of indeterministic models of computation which slightly modify the standard model of quantum computation. Th…
