Maassen van den Brink, Mitchell (author)In this thesis, research was done in the area of interacting particle systems. Especially, the symmetric exclusion process with local perturbations was investigated. These perturbations, were in the form of sinks and sources, which add or take away particles at certain rates. Moreover, simulations were done for the asymmetric exclusion process....bachelor thesis 2023

Flór, Ian Matthias (author)The detection of nonAbelian exchange statistics is an open challenge which holds important promises for the advent of topological quantum computation. A recent work proposes to rely on the edges to reveal the braiding statistics of nonAbelian anyons in the bulk, in an entirely deterministic dynamical process. A timedependent gap in a Josephson...master thesis 2023

Delboo, Maxime (author)This thesis contains a rigorous derivation of the path integral formulation of the Isingmodel with multiple original proofs. Besides that, thesis also contains various resultsof simulations of the 2D square lattice Ising Model with nearestneighbour interactionsusing the SwendsenWang algorithm. Using finite size scaling to find critical...bachelor thesis 2022

Fillerup, Chai (author)Quantum communication has been shown to be vastly superior to classical communication in many problems. However no general statements exist which tells us how much better quantum communication is to its classical counterpart. In this thesis it was studied the minimum amount of classical bits required to exactly simulate a quantum communication...bachelor thesis 2022

Ates, Matthijs (author)The aim of this thesis is to simulate quantum spin chains at a finite temperature. This has been achieved by using purification to write the incoherent thermal states of the spin chain as pure states, after which the matrix product state (MPS) formalism to simulate the spin chain. The influence of temperature on the spin chain has been tested by...bachelor thesis 2022

Gort, Timo (author)<i>Context.</i> In the nearfuture, exoplanets can be observed directly through telescopes. Although the resolution of the planet's image will only be one pixel at first, the intensity of this pixel will change over time because of the orbit around its host star and its diurnal rotation. This intensity as a function of time is called the light...bachelor thesis 2022

Koot, Kees (author)In this thesis the behaviour of a Bose Einstein condensate is explored that consists of bosons that annihilate. In order to do this a system where bose einstein condensation occurs is modeled as a Zero Range process which is a special case of a Markov process.<br/>First we made a single slow site Zero range process with uniform rates and see how...bachelor thesis 2022

Polshchykova, Zoya (author)In this thesis, gate set tomography (GST) has been conducted on the nitrogen vacancy center (NV). Gate set tomography is a protocol for characterization of logic operations (gates) on quantum computing processors. The NV’s electron served as a qubit. The quantum circuits were run both experimentally as well as on an NVsimulator. GST is...bachelor thesis 2022

Loor, Stephan (author)In the past few years, the search for good quantum low density parity check (qLDPC) codes suddenly took flight, and many different constructions of these codes have since been presented, including many product constructions. As these code constructions have a natural interpretation in the language of homology, this thesis studies the interplay...master thesis 2022

Aliberti, Dylan (author)The aim of this thesis was to test the efficiency in practice of an analytical propagator with collision detection for <i>N</i>body Keplerian systems. This can be used to simulate the evolution of a protoplanetary disk, which gives insight into how planetary systems form. The analytic propagator calculates collisions one by one, while a...bachelor thesis 2022

Popa, Vlad (author)In an attempt to find alternatives for solving partial differential equations (PDEs)<br/>with traditional numerical methods, a new field has emerged which incorporates<br/>the residual of a PDE into the loss function of an Artificial Neural Network. This<br/>method is called PhysicsInformed Neural Network (PINN). In this thesis, we study dense...bachelor thesis 2022

Neves Almeida Lopes, Tamira (author)When looking up to the sky and trying to detect the photons of far away stars that are still in formation, we can get access to knowledge we never had before. In order to do this, we must make sure we truly understand the nature of how photons behave in accordance to each other and to our detectors.In quantum optics we can see that these photons...bachelor thesis 2022

Arens, Patricia (author)In the last decades there has been an increasing interest in computing the local strain at the atomic scale of materials. By knowing aspects of the local strain in a lattice, one has information about measurements of distortions of lattice parameters concerning shifts, deformations and defects computed with respect to a smooth, defectfree...bachelor thesis 2022

Claes, Joep (author)Random walks have been applied in a many different fields for a long time. More recently, classical random walks are being used in wide variety of computer algorithms used to solve complex computational problems like 2SAT, 3SAT and the estimation of the volume of complex bodies. In this thesis we look into the quantum version of the familiar...bachelor thesis 2022

Kirchner, Joris (author)Neural network is an active research field which involves many different (unsolved) issues, for example, different types of configuration of the network architectures, training strategies, etc. Amongst these active issues, the choice of loss (or cost) functions plays an important role in how a neural network model is to be optimized (trained)...bachelor thesis 2022

Wanningen, Nicky (author)For scaling up the qubits in silicon quantum computers, it is vital to determine crosstalk effects that can lower the fidelity of the computer. <br/>In this computational project, we examine singlequbit gatefidelities in the presence of crosstalk for uncoupled spin qubits that are driven with Xgates via electron dipole spin resonance (EDSR)....bachelor thesis 2022

Baas, Floris (author)Chiral induced spin selectivity (CISS) is an unexplained phenomenon in physics, in which the interaction within chiral molecules brings about a selectivity in the spin of the electrons.<br/>The Breit interaction has been suggested as a possible explanation, but has not yet been researched in the context of CISS.<br/>In this thesis, first a...bachelor thesis 2022

Vermeer, Wiggert (author)Synchronisation refers to the tendency of coupled oscillators to move in phase with one another over time, departing from their own natural frequency. This phenomenon occurs in almost all branches of science, engineering, and social life. Synchronisation is a well understood concept in classical mechanics. Quantum synchronisation involves...bachelor thesis 2022

Witmer, Brian (author)Quantum technology is evolving faster than ever. Currently, all eyes are on the quantum computer, the promising computer that can solve problems which are unsolvable for regular computers. In order to understand this new technology, it is necessary to understand the qubit, the basic unit of quantum information. This can be done by means of the...bachelor thesis 2022

van Poelgeest, Sam (author)In the field of quantum information theory, it is wellknown that the purely quantum phenomenon called quantum entanglement can boost the capacity of a quantum channel, which is called the superadditivity of the capacity. Shor showed in his breakthrough paper on the equivalence of additivity conjectures that this superadditivity is equivalent to...master thesis 2022
