van Veen, J. (author)Quantum computers can solve some problems exponentially faster than classical computers. Unfortunately, the computational power of quantum computers is currently limited by the number of working qubits. It is difficult to scale up these systems, because qubits are easily affected by noise in their environment. This noise leads to decoherence:...doctoral thesis 2019

Kroll, J.G. (author)Majorana bound states (MBSs) are novel particles predicted to be created when superconductor/semiconductor hybrid structures with strong spinorbit coupling are subjected to strong magnetic fields. Expected to exhibit nonAbelian exchange statistics, they could form the basis of a new kind of quantum computer that is inherently protected from...doctoral thesis 2019

de Moor, M.W.A. (author)Quantum technology is a promising area of research, with the quantum computer as the prime example. Quantum computers can perform calculations thought to be impossible by conventional means. The fundamental building block of a quantum computer is a qubit, which is a quantumsystem which can be used to process and store quantuminformation. Most...doctoral thesis 2019

Proutski, A. (author)Materials possessing superconducting properties are highly sought after due to their potential technological applications. Much of the work has focused on utilising a thin insulating barrier separating a pair of superconducting electrodes, a Josephson junction, as a workhorse in the field of superconducting based quantumcomputation. Yet such...doctoral thesis 2019

Lüthi, F. (author)Quantum computers promise to solve certain problems such as quantum chemistry simulations much more efficiently than their classical counterparts. Although it is still unclear what material system will ultimately host largescale quantum computers, solidstate systems are promising candidates due to their inherent scalability and advanced...doctoral thesis 2019

Mirzaei, B. (author)Quantum cascade laser (QCL) technology has made a breakthrough in THz radiation sources, opening a new window into variety of applications. QCLs are compact, lowconsumption and narrow linewidth lasers with relatively high output powers, capable to emit radiation across the whole superTHz (26 THz) range. These are all demanded for spectroscopy...doctoral thesis 2018

Gül, Ö (author)The dissertation reports a series of electron transport experiments on semiconductor nanowires towards realizing the hypothesized topological quantum computation. A topological quantum computer manipulates information that is stored nonlocally in the topology of a physical system. Such an operation possesses advantages over the current quantum...doctoral thesis 2017

Szombati, D.B. (author)Josephson junctions form a twolevel system which is used as a building block for many types of superconducting qubits. Junctions fabricated from semiconducting nanowires are gatetunable and offer electrostatically adjustable Josephson energy, highly desirable in qubit architecture. Studying nanowire weak links is therefore important for future...doctoral thesis 2017

Zuo, K. (author), Mourik, V. (author)Majorana fermions are exotic elementary particles predicted in 1937 by Ettore Majorana. Although heavily searched for, they have never been found in nature up to date. In the past decades, with the progress in theory, theoretical physicists predicted that Majorana fermions might emerge in certain exotic classes of condensed matter systems, where...doctoral thesis 2016

Beukman, A.J.A. (author)This thesis includes two research directions both aim to discover a building block for topological quantum computing. First, in Chapter 3, a novel setup is designed, built, and tested, that can electrostatically gate a material without endangering the materials pristine quality. The setup was designed with the goal to reveal nonAbelian...doctoral thesis 2016

Bouwes Bavinck, M.H. (author)In the future world of quantum communication and computing, infomation cannot be hacked and computers solve difficult problems, such as factorizing large number or searching in a large databases, much faster than possible with ordinary computers. However, to realize such systems still much research is needed. One of the systems that has gained a...doctoral thesis 2016

Ristè, D. (author)Superconducting circuits have recently risen to the forefront of the solidstate prototypes for quantum computing. Reaching the stage of robust quantum computing requires closing the loop between measurement and control of quantum bits (qubits). This thesis presents the realization of feedback control of superconducting qubits based on...doctoral thesis 2014

Quantum Transport in Indium Antimonide Nanowires: Investigating building blocks for Majorana devicesVan Weperen, I. (author)Recently ideas to engineer Majorana fermions in the solid state have been developed. These Majoranas, quasiparticles that are their own antiparticle, have received much attention, as they are expected to fulfill nonAbelian exchange statistics and could potentially function as faulttolerant quantum bits. This thesis focuses on a Majorana host...doctoral thesis 2014

Bulgarini, G. (author)In this thesis work, I studied individual quantum dots embedded in onedimensional nanostructures called nanowires. Amongst the effects given by the nanometric dimensions, quantum dots enable the generation of single light particles: photons. Single photon emitters and detectors are central building blocks of future communication technologies....doctoral thesis 2014

Pfaff, W. (author)This thesis presents a set of experiments that explore the possible realisation of a macroscopic quantum network based on solidstate quantum bits. Such a quantum network would allow for studying quantum mechanics on large scales (meters, or even kilometers), and can open new possibilities for applications in quantum information processing. A...doctoral thesis 2013

Heeres, R.W. (author)This thesis describes experiments with surface plasmons: light confined to metaldielectric interfaces. By using metals it is possible to make extremely small waveguides for light, even below the diffraction limit of dielectric structures. We study the quantum aspects of single plasmons in particular. To this end we create small circuits of gold...doctoral thesis 2012
