van Nederveen, Milou (author)Quantum Batteries (QBs) are quantum-mechanical devices for energy storage, gaining interest due to a potential quantum advantage in power. Recently, the first experimental implementations of QBs were realised. This study characterises the superconducting transmon qubits of Starmon-5 as QBs using the Quantum Inspire platform. In addition to...master thesis 2024

van der Zalm, Joost (author)One of the main components used in superconducting quantum chips is the Josephson junction. Currently when fabricating Josephson junctions, the resistance uniformity at wafer-scale is not optimal. It is also known that an annealing process can alter the junction resistance and with it the qubit frequency. However, laser annealing has only shown...master thesis 2022

Nagtegaal, M.A. (author), Blaauboer, M. (author)We propose a quantum-mechanical device consisting of transmon qubits connected to single-photon transmission lines that can be used to perform a boolean quantum private query on a database. Using numerical simulations verified by analytical calculations we analyse the dynamics of the query process in the proposed system by calculating the...journal article 2019

Wesdorp, Jaap (author)We generate entanglement between two transmon qubits each coupled to a readout resonator and located on different chips via engineering a half-parity measurement. This measurement does not distinguish |01> from |10>, thus if started in an initial full twoqubit superposition it will project the qubits to an odd Bell state 50% of the time....master thesis 2017

Hortensius, J. (author)In transmon qubits, the leading source of errors for quantum gates is the existence of higher energy levels, besides the |0> and |1> states which form the computational subspace. Several methods have been developed to eliminate these errors systematically by clever use of the available experimental controls. In this bachelor thesis we focus on...bachelor thesis 2015
