This thesis is a collection of theoretical works aiming at adjusting quantum algorithms to the hardware of quantum computers.

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

Met de NMR faciliteit doen we onderzoek naar de synthese van paramagnetische moleculen om kennis te vergaren over de structuur en dynamiek van eiwitten. Deze kennis kan dienen als basis voor een medicijn dat zich hecht aan een eiwit of voor de ontwikkeling van vaccins. Medicijnontwikkeling is één van…

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

Making a dynamic substance stock model in order to conduct scenario analyses and make forecasts.

Dissolving microneedles are a subgroup of microneedle types that completely dissolve within the skin. During this dissolving process the vaccine, stored in the needle matrix, is released into the skin.

Waar gaan de quantummechanica, de relativiteitstheorie en de zwaartekracht elkaar vinden? Wat is het missende stukje? Of is er een compleet nieuwe theorie die alle vormen van materie elegant beschrijft?

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

Promotores: Prof.dr.G.R. de Snoo and Dr. R. Heijungs

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

Algoritmen ontwerpen is een van de onderzoeksonderwerpen waar Leiden sterk in is. Want supercomputers moeten niet alleen gebouwd worden, maar ook geprogrammeerd. Wetenschappers van internationale faam doen hier onderzoek naar.

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.
