  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

  5. 4. Quantum state tomography of attosecond electron wavepackets

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

    Author : Ron Demjaha; [2022]
    Keywords : quantum physics; quantum state tomography; atomic physics; quantum optics; density matrix; entanglement; state mixing; fano resonances; two-photon absorption; Physics and Astronomy;

    Abstract : In this master thesis, a broad theoretical description is done of a novel quantum state tomography protocol called KRAKEN. This protocol is meant for the determination of the density matrix of an electronic state created by absorption of XUV radiation in the vicinity of a Fano resonance. At first, a description of the KRAKEN protocol is provided. READ MORE
