1. Generation and detection of entangled single-photon pairs
University essay from Uppsala universitet/FREIAAbstract : 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

2. III-V semiconductor waveguides for application in nonlinear optics.
University essay from KTH/Tillämpad fysikAbstract : This thesis presents studies on III-V semiconductor waveguides with particular emphasis on second-order optical nonlinearity. The nonlinear processes that were investigated in this thesis are the Second Harmonic Generation (SHG) and the Spontaneous Parametric Down-Conversion (SPDC). READ MORE

3. 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/FysikAbstract : 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

4. Generating quantum entangled photons
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : In this project a laser setup was constructed, quantum entangled photons were generated and two different methods were used to show said entanglement. The entangled photons were generated through a process called spontaneous parametric down conversion (SPDC). READ MORE

5. Generation of the Bound Entangled Smolin State and Entanglement Witnesses for Low-Dimensional Unitary Invariant States
University essay from Teoretisk fysikAbstract : Quantum entanglement is employed as a resource throughout quantum information science. However, before entanglement can be put to intelligent use, the issues of its production and detection must be considered. This thesis proposes four schemes for producing the bound entangled Smolin state. READ MORE
