Enthoven, Luc (author)Disruptive changes in the fields ofcryptography and quantum chemistry can be achieved through quantum computing,as specific computations can be sped up significantly. Thousands to millions ofqubits are required to perform these computations, illustrating the need forlarge quantum computers. These qubits must be cooled to...master thesis 2020

Jansen, S.E.D. (author)This thesis deals with nto1 entanglement distillation protocols for bipartite quantum systems in a group theoretical setting. The local operations in the protocols are restricted to Clifford operations. An efficient representation of the elements of the Clifford group in terms of binary matrices is presented. Moreover, a characterization of...bachelor thesis 2020

Diephuis, S. (author)Topos theory and quantum mechanics are both known for having a logic that is different from ordinary logic. With this in mind, much work has been done on unifying these two fields. Loveridge, Dridi and Raussendorf apply this unification to measurementbased quantum computation [14], revealing links between computation, contextuality and the...bachelor thesis 2020

van Houte, Roy (author)Quantum coin flipping is a cryptographic primitive in which two or more parties that do not trust each other want establish a fair coin flip. These parties are not physically near each other and use quantum communication channels to interact. A quality of protocols is measured by the best possible cheating strategy, which is the solution of a...master thesis 2020

Kuś, Gaweł (author)The datadriven approach shows great potential for designing new materials with unprecedented properties by using machine learning and optimization. Recently, a datadriven framework was successfully applied to design a unit cell of metamaterial achieving supercompressibility, despite being built out of brittle base material. The key element of...master thesis 2019

Mulderij, Jesse (author)Over the course of the last decade, an interest has emerged in nearest neighbor constraints for quantum circuit design. The challenge herein is to bothminimize the running time of a circuit and tomodify it such that quantum gates only act on adjacent qubits while leaving the desired computational operation intact. These modifications involve the...master thesis 2019

Ubbens, Otmar (author)With the rapid development of Quantum Computers (QC) and QC Simulators, there will be an increased demand for functioning Quantum Algorithms in the near future. Some of the most ubiquitously useful algorithms are solvers for linear systems of equations. Since the conception of the Quantum Linear Solver Algorithm (QLSA) by Harrow, Hassidim and...bachelor thesis 2019

Leijenhorst, Nando (author)Quantum error correction is needed for future quantum computers. Classical error correcting codes are not suitable for this due to the nature of quantum mechanics. Therefore, new codes need to be developed. A promising candidate is the toric code, a surface code, because of its locality and its high error correcting capability and thresholds ...bachelor thesis 2019

Padalia, Pinakin (author)Voltage references are one of the fundamental building blocks for designing any analog processing circuit. It serves as a reference for Analog to Digital Converters (ADCs), Digital to Analog Converters (DACs), power/voltage regulators and other measurement and control circuits. The performance of all these circuits cannot be better than the...master thesis 2019

Overwater, Ramon (author)The quantum bits (qubits) at the core of any quantum computers are so fragile that quantum error correction(QEC) schemes are needed to increase their robustness and enable faulttolerant quantum algorithms. The surface code is one of the most popular QEC schemes, but it requires the availability of an efficient decoder. While neural networks...master thesis 2019

Driebergen, Tim (author)Currently there are no efficient quantum algorithms for the addition of realvalued numbers. In classical computers addition is performed by using barrel shifters, a concept proven to be very inefficient as a quantum circuit due to its many garbage outputs when the barrel shifter is made reversible. This thesis aims to design a quantum algorithm...bachelor thesis 2019

Yang, Yaoling (author)Quantum computers hold the promise to solve some hard problems that are intractable for even the most powerful current supercomputers. One of the most famous examples is Shor's algorithm for factorizing large numbers, which has exponential speedup compared to its best classical counterparts.<br/>However, running such an algorithm will require to...master thesis 2019

Salentijn, Jaco (author)Quantum computers are able to deal with large problems, like molecular modelling, financial prediction and cryptography. A classical controller is used to control the qubits of the quantum computer. A proposed controller, operating at 4K, needs a clean voltage supply in order to function well.

van Staveren, Job (author)Quantum computers seem very promising in solving problems that are too large to be solved by classical computers that are available today. However, to generate reasonable amounts of computing power, many qubits will be required. Each of the qubits has to be individually controlled and needs to be kept at cryogenic temperatures. To allow for the...master thesis 2018

Cornelissen, Arjan (author)In 2005, Jordan showed how to estimate the gradient of a realvalued function with a highdimensional domain on a quantum computer. Subsequently, in 2017, it was shown by Gilyén et al. how to do this with a different input model. They also proved optimality of their algorithm for \ell^\infty approximations of functions satisfying some...master thesis 2018
