1. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes
University essay from Linköpings universitet/InformationskodningAbstract : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. READ MORE

2. Ray Tracing Algorithm for Dielectric Domes
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. READ MORE

3. Time-dependent light-matter coupling and quantum dynamics
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. READ MORE

4. Development and Analysis of a Gaseous Hydrogen-Oxygen Rotating Detonation Combustor
University essay from KTH/Kraft- och värmeteknologiAbstract : Theory suggests that more efficient rocket propulsion can possibly be achievedby utilizing a pressure-gain detonative combustion process instead of conventional deflagration combustion. To demonstrate this, rotating detonation engines that sustain one or several detonation waves in an annular enclosure havebeen a subject of research for decades. READ MORE

5. Optical Detector for Microfluidics
University essay from Högskolan i Halmstad/Akademin för informationsteknologiAbstract : This project arose from the need to filter the sampled data and eliminate non-useful information in Serial Crystallography in Microfluidic Device (MFD)by using a portable optical detector placed around the channel. By testing sixteen different configurations, always using an LED as a source and a photodiode as a light sensor, changes in the channel due to the passage of air bubbles were detected. READ MORE
