  1. 1. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

    University essay from Linköpings universitet/Informationskodning

    Author : Hilma Karlsson; [2023]
    Keywords : Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

    Abstract : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. 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

  4. 3. Constructing Numerical Methods For Solving The Guiding Equation In Bohmian Mechanics

    University essay from Uppsala universitet/Materialteori

    Author : Nilsson Robert; [2021]
    Keywords : Bohmian mechanics; De Broglie Bohm Theory; Numerical Methods;

    Abstract : The aim of this thesis was to simulate a part of a proposed experiment by Lev Vaidman by using Bohmian mechanics. To do this a numerical method for solving the Schrödinger equation and theguiding equation was created, with several ways of making the simulation more efficient. READ MORE

  5. 4. Design and optimization of multi-port beam splitters on integrated photonic circuits

    University essay from Linköpings universitet/Informationskodning

    Author : Susmita Saha; [2021]
    Keywords : Multiport Beam Splitter;

    Abstract : Multiport beam splitter is a new research topic in quantum communication. To improve the security system, the dimension/capacity of quantum communication should increase. In this thesis, design, simulation and methodology of NXN multiport beam splitter on a photonic integrated circuit is explained. READ MORE

  6. 5. A Study in How Welding Parameters Affect the Porosity in Laser Welded High Pressure Die Cast AM50 Magnesium Alloy

    University essay from KTH/Materialvetenskap

    Author : Edwin Bergstedt; [2017]
    Keywords : Laser welding; AM50; Die Cast; Magnesium; Porosity;

    Abstract : There are a need for reducing the weight of vehicles, one solution is to implement cast lightweight materials such as the high pressure die cast AM50 magnesium alloy. The weldability of this cast alloy is poor and to implement the use of the alloy commercially a welding process is needed that limits the porosity of the weld. READ MORE
