1. 1. Modulation of the optical properties of quantum dots by surface acoustic waves

   University essay from KTH/Tillämpad fysik

   Author : Tanguy Schetelat; [2023]
   Keywords : Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

   Abstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE

3. 2. Demonstrating quantum entanglement and Hong-Ou-Mandel effect, using type-II spontaneous parametric down conversion with C programming for data collection

   University essay from KTH/Fysik

   Author : Erik Svanberg; Johan Johannisson Lundquist; [2022]
   Keywords : Quantum entanglement; polarization; HOM; Hong-Ou-Mandel; indistinguishability; type-II SPDC; spontaneous parametric down conversion; non-linear crystal; beam splitter; indistinguishable photons; data collection in C;

   Abstract : Spontaneous parametric down conversion (SPDC) is used to generate quantum entangled photons through a non-linear crystal. The entanglement of photons is demonstrated by observing the effects of indistinguishability on photons, first through time and energy, then by polarization. The Hong-Ou-Mandel (HOM) effect was also demonstrated. READ MORE
