Vuik, A. (author), Eeltink, D. (author), Akhmerov, A.R. (author), Wimmer, M.T. (author)One of the promising platforms for creating Majorana bound states is a hybrid nanostructure consisting of a semiconducting nanowire covered by a superconductor.Weanalyze the previously disregarded role of electrostatic interaction in these devices. Our main result is that Coulomb interaction causes the chemical potential to respond to an applied...journal article 2016

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

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

(author)A major step toward fully integrated quantum optics is the deterministic incorporation of high quality single photon sources in on-chip optical circuits. We show a novel hybrid approach in which preselected III-V single quantum dots in nanowires are transferred and integrated in silicon based photonic circuits. The quantum emitters maintain...journal article 2016

(author)In this paper several designs to maximize the absorption efficiency of superconducting-nanowire single-photon detectors are investigated. Using a simple optical cavity consisting of a gold mirror and a SiO<sub>2</sub> layer, the absorption efficiency can be boosted to over 97%: this result is confirmed experimentally by the realization of an...journal article 2016

(author)Superconducting nanowires are the dual elements to Josephson junctions, with quantum phase-slip (QPS) processes replacing the tunneling of Cooper pairs. When the QPS amplitude ES is much smaller than the inductive energy EL, the nanowire responds as a superconducting inductor. When the inductive energy is small, the response is capacitive. The...journal article 2015

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 non-Abelian exchange statistics and could potentially function as fault-tolerant quantum bits. This thesis focuses on a Majorana host...doctoral thesis 2014
