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. Live 3D imaging quantum LiDAR
University essay from KTH/Tillämpad fysikAbstract : In this thesis, I demonstrate a singlephoton Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eyesafe laser pulses. Thesystem was built using off-the-shelf optical components and analysis was performedusing open-source software. READ MORE

4. Distributed Temperature Sensing Using Phase-Sensitive Optical Time Domain Reflectometry
University essay from KTH/Tillämpad fysikAbstract : This thesis explores and evaluates the temperature measuring capabilities of a phase-sensitive optical time-domain reflectometer (φ-OTDR), which exploits Rayleigh backscattering in normal single mode optical fibers. The device is constructed and its setup explained, and a protocol for making temperature measurements with it is developed. READ MORE
