1. Quantum Espionage
University essay from KTH/Tillämpad fysikAbstract : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. READ MORE

2. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

3. Fano Resonances in Time-Dependent Wells
University essay from Uppsala universitet/MaterialteoriAbstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

4. Digital Front End Algorithms for Sub-Band Full Duplex
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

5. Laboratory starlight simulator for future space-based heterodyne interferometry
University essay from Luleå tekniska universitet/RymdteknikAbstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE
