2. 1. Bell tests and the no-signalling assumption

   Author : Massimiliano Smania; Mohamed Bourennane; Ingemar Bengtsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum; quantum optics; Bell tests; CHSH inequality; entanglement; fysik; Physics;

   Abstract : Bell's theorem was originally meant for testing fundamental properties of Nature, namely local realism. However, through the years it has become a powerful device for certifying encryption security, randomness, and entanglement among other properties. READ MORE

4. 2. Photonic multipartite entanglement : Generation, measurement and applications

   Author : Massimiliano Smania; Mohamed Bourennane; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum information; entanglement; Bell tests; POVM; device-independent; self-testing; quantum optics; prepare-and-measure; fysik; Physics;

   Abstract : We are currently witnessing a fundamental change in the field of quantum information, whereby protocols and experiments previously performed in university labs are now being implemented in real-world scenarios, and a strong commercial push for new and reliable applications is contributing significantly in advancing fundamental research. In this thesis and related included papers, I first look at a keystone of quantum science, Bell's theorem. READ MORE

5. 3. A reliability study of electronic components and electret foils, including latent failures due to submission to electrostatic discharges in a historical retrospective

   Author : Sten Hellström; KTH; []
   Keywords : reliability; failure mechanism; acceleration tests; ESD; latent failure; ;

   Abstract : This thesis deals with the reliability and life-time ofelectronic components and ways to determine these factors.Plastic encapsulated and open test circuits were assessed atdifferent humidity and temperature conditions. From the resultsan acceleration factor could be derived using the Arrheniusrelation. READ MORE

6. 4. Photonic quantum information and experimental tests of foundations of quantum mechanics

   Author : Magnus Rådmark; Mohamed Bourennane; John Rarity; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; Physics; Fysik; fysik; Physics;

   Abstract : Entanglement is a key resource in many quantum information schemes and in the last years the research on multi-qubit entanglement has drawn lots of attention. In this thesis the experimental generation and characterisation of multi-qubit entanglement is presented. Specifically we have prepared entangled states of up to six qubits. READ MORE

7. 5. Quantum technologies for secure communications

   Author : Junior Ricardo Gonzales Ureta; Ana Predojević; Marcus Huber; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum technologies; quantum information; quantum optics; Physics; fysik;

   Abstract : Quantum technologies promise to revolutionize a variety of fields such as metrology, cryptography or computing, among others. The resources that quantum mechanics offers allow us to design faster optimization algorithms, to improve security in communications, and to measure quantities beyond the grasp of current technology.
