  1. 1. Quantum Espionage

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Carlo Ninic Svensson; [2023]
    Nyckelord :Quantum Nano Photonics; SNSPD; OTDR; Nano Kvantfotonik; SNSPD; OTDR;

    Sammanfattning : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. LÄS MER

  3. 2. Extreme renovation of concrete buildings

    Master-uppsats, KTH/Betongbyggnad

    Författare :Simon Hardo; Daniel Maher; [2023]
    Nyckelord :;

    Sammanfattning : The global climate crisis and the need to reduce carbon emissions have brought attention to the construction and real estate sector, which has a significant environmental footprint. However, many real estate developers opt for demolition and new construction instead of renovating existing buildings due to challenges such as low floor heights and stringent sustainability requirements.

    Nyckelord :Closed-loop Systems; Tunable Antennas; Radio Frequency RF ; MCU in closed-loop Systems; Adaptable Tuning; Antenna Impedance Matching Adaptive Antennas.;

    Sammanfattning : Tunable antennas have emerged as a promising technology to address the challenges of achieving optimal performance across a wide range of frequencies. This abstract presents a study focused on designing and implementing an ideal antenna system design within a closed-loop system. Background. LÄS MER

  5. 4. Digital Microwave Control of Superconducting Qubits

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Giuseppe Ruggero Di Carlo; [2022]
    Nyckelord :Superconducting qubit; High-fidelity readout; Real-time reset; iSwap gate; FPGA; RFSoC; template matching.; Supraledande kvantbit; Avläsning med hög tillförlitlighet; realtidsåterställning; iSwap-grind; FPGA; RFSoC; mallmatchning.;

    Sammanfattning : We manipulate two superconducting qubits using digital microwave electronics. Starting fromtheir characterization, we develop a real-time reset scheme and implement the iSwap gate. Thequbits’ parameters are obtained using standard single-qubit characterization techniques, such asRabi and Ramsey oscillations and frequency sweep of the resonators. LÄS MER
