1. 1. Generation and detection of entangled single-photon pairs

   University essay from Uppsala universitet/FREIA

   Author : Gabriella Tesfamichael Habtezion; [2024]
   Keywords : ;

   Abstract : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. READ MORE

3. 2. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Máté Károly Tóth; [2023]
   Keywords : Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

   Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

4. 3. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isa Clementsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

5. 4. James Webb Space Telescope Observations of Jupiter’s Moon Europa

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Aulon Nura; Isac Engblom; [2023]
   Keywords : ;

   Abstract : The creation of life has puzzled humanity since the dawn of time. With the launch of thecutting-edge James Webb Space Telescope (JWST) at last year's closing, the next step in humanity'ssearch for life has been taken. READ MORE

6. 5. Embedded digital filter design and implementation

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Xiao Su; [2023]
   Keywords : ;

   Abstract : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer.
