  1. 1. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

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

    Författare :Máté Károly Tóth; [2023]
    Nyckelord :Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

    Sammanfattning : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

  3. 2. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Martin Clason; [2023]
    Nyckelord :shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

    Sammanfattning : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. LÄS MER

  4. 3. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sara Persia; [2022]
    Nyckelord :Parametric amplifier; kinetic inductance; superconducting NbTiN nanowires; Parametrisk förstärkare; kinetisk induktans; supraledanden NbTiN- nanotrådar;

    Sammanfattning : Parametric amplifiers are essential for analyzing and measuring the weak signals generated byquantum circuits at cryogenic temperatures. This project aims to realize a low noise travelingwave parametric amplifier (TWPA) by exploiting the nonlinear current dependence of thekinetic inductance of superconducting NbTiN nanowires. LÄS MER

  5. 4. Cold amplification and fiber coupling of a super-conducting nanowire single-photon detector

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Stéphane Cohen; [2022]
    Nyckelord :Applied Physics; Tilllämpad fysik;

    Sammanfattning : Single-photon detectors are an essential tool for quantum photonics: one can harness the quantum properties of single photons for quantum communication as well as use the detectors in low illumination applications.Superconducting nanowire single-photon detectors offer high detection efficiency over a widerange of wavelengths, low dark counts, and a good timing resolution compared to single-photonavalanche diodes.

  7. 5. A Modular Approach to Design and Implementation of an Active GNSS Antenna

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Ulrik Hecktor; [2022]
    Nyckelord :GNSS; RTK; circular patch antenna; LNA; stacked patch antenna;

    Sammanfattning : This master’s thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. LÄS MER
