  1. 11. Digital Microwave Control of Superconducting Qubits

    University essay from KTH/Tillämpad fysik

    Author : Giuseppe Ruggero Di Carlo; [2022]
    Keywords : 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.;

    Abstract : 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. READ MORE

  3. 12. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Author : Louise Olausson; [2022]
    Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

  4. 13. Quasicrystal nanowires in SNS-junctions

    University essay from Uppsala universitet/Materialteori

    Author : Anna Sandberg; [2022]
    Keywords : quasicrystal; Fibonacci quasicrystal; superconductivity; SNS-junction; Josephson junction; proximity effect; Josephson current; Bogoliubov-de Gennes method;

    Abstract : Quasicrystals are systems that are ordered but not periodic. They do however still have long-range order and well-defined diffraction peaks. This leads to interesting properties, like critical states which are neither extended nor localized, and to topological invariants and edge states. READ MORE

  5. 14. Single Photon LSCM in the NIR Range

    University essay from KTH/Tillämpad fysik

    Author : Klara Wallenbro; [2022]
    Keywords : LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

    Abstract : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

  6. 15. Cryo-CMOS ICs for Scalable Superconducting Nanowire Single Photon Detectors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tereza Viskova; [2022]
    Keywords : Superconducting nanowire single photon detector; Quantum; Photonic; Readout; Cadence Virtuoso; Cryogenic; Digital; Supraledande nanotrådsdetektorer; Avläsning; Cadence Virtuoso; Kryogen; Digital;

    Abstract : Superconducting nanowire single-photon detectors are the most promising technology in quantum photon information. They offer high speed, high detection efficiency, low dark count rate as well as low timing jitter compared to other single photon detection solutions. READ MORE
