Cluster-state creation in liquid-state NMR
… is devoted to a class of multiparticle entangled states known as the cluster-states. In particular, we focused on a system of four spins and studied the entanglement properties of a four-qubit cluster-state, using a set of entanglement measures for quantifying multipartite entanglement. We then …

Measurement-based quantum computation with cluster states
… on a highly entangled multi-particle state, the cluster state. We prove universality of the QCc, describe the underlying computational model and demonstrate that the QCc can be operated fault-tolerantly. In Chapter 2 we show that the QCc can be regarded as a simulator of quantum logic …

Using the qubus for quantum computing
… purposes - quantum simulation, and generating cluster states. Quantum simulation is the idea of using a quantum computer to simulate a quantum system. I focus on conducting a simulation of the BCS Hamiltonian. I demonstrate how to perform the necessary two qubit operations in a controlled …

Scheduling in a Database-Based Distributed Operating System
… This database OS (DBOS) centralizes all cluster state in a uniform data model: database tables stored in a high-performance, distributed, main-memory database management system. Operations on this state will be performed via serverless, stateless tasks. This thesis presents work done to …

Benchmarking measurement-based quantum computation on graph states
… that operates on a prepared entangled graph state, typically a cluster state. In this dissertation, we will detail the creation of graph states across various physical platforms using different entangling gates. We will then benchmark the quality of graph states created with error-prone …

Application of quantum walks on graph structures to quantum computing
… introduce an experimental scheme for generating cluster states, a universal resource for quantum computation. We give an explicit construction which provides a link between the circuit model of quantum computation, and a graph structure on which the discrete time quantum walk traverses, …

System characterisation under experimental constraints
… Currently characterising and verifying quantum states is a hard problem. Verification is necessary in order to understand and control quantum systems. There are also issues in the physical realisation of these systems, the apparatus used does not match the quantum scale and so produces errors in …

Quantum Information Processing using the Power-of-SWAP
… invariant subspaces and associated vector-states. Some interesting patterns of states are found including onedimensional invariant subspaces spanned by W-states and the Hamming-weight preserving symmetry of the vectors spanning the various invariant subspaces. We also devise new ways of …

Relative performance of measurement-based quantum computation models under noisy conditions
Thesis documenting the analysis of two similar models of measurement-based quantum computation subject to noise, individually and in comparison to one another, to determine if one hosts any innate advantage over the other.

Photonic integration of electron-nuclear spin systems in semiconductor quantum dots
… on the measurement of multidimensional photonic cluster states. These are states of highly entangled photons, which can be generated using the light-matter interface of an electron and the nuclear spins within an optically active QD. Here we integrate the electron-nuclear spin system of a …

Elongated microswimmers: influence of hydrodynamics
… ratio and density, we observe a disordered state, dynamic swarms, a single swarm, and a jammed cluster state and characterize them accordingly. We also investigate a wide range of aspect ratios and densities for pushers and pullers and provide corresponding state diagrams. The flow field of …

A Hybrid State/Event Driven Communication-based Control for DC Microgrids
… In this thesis, the technical merits of clustering multiple microgrids during blackouts on the overall stability and supply availability have been investigated.</p> <p>We propose to use the existing underground distribution grid infrastructure, if applicable, during blackouts to form …
