  1. 1. Automation of Pulse Repetition Interval Modulation Classification

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karolina Barrios; [2021]
    Nyckelord :;

    Sammanfattning : Radar systems are essential in the field of electronic warfare and radar signals are used for estimating speed, location and direction of an object. A radar system sends out small transmissions called pulses. The interval between the start of one pulse to the start of the next pulse is called pulse repetition interval (PRI). LÄS MER

  2. 2. Two-Photon Excitation of a GaAs Quantum Dot by Electro-Optically Modulating a Continuous Wave Laser

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Julia Schauman; Linnea Bendrot; [2020]
    Nyckelord :;

    Sammanfattning : One of the most important steps towards enabling quantum communication would be to successfully integrate single-photon emitters and quantum memories, enabling the development of quantum repeaters. This is why, as part of a larger project, the objective of this bachelor thesis was to retrieve single-photons suitable for storage inside a Rubidium-based quantum memory. LÄS MER
