  1. 16. Sharing Quantum Resources Across a Metropolitan Network

    University essay from KTH/Tillämpad fysik

    Author : Martin Carlnäs; [2022]
    Keywords : QKD; Entanglement; SNSPD; Quantum Dot; Exciton; Biexciton; QKD; Kvantsammanflätning; SNSPD; Kvant Prick; Exciton; Biexciton;

    Abstract : Kvantsammanflätning har varit ett populärt ämne bland fysiker i snart 100 år då det tydligt belyser hur annorlunda kvantmekanikens värld är jämfört med den klassiska verklighet vi lever i. Med tiden har kvantsammanflätning blivit mer och mer välförstått och teknologier ämnade att utnyttja det har de senaste årtionden kommit allt närmare till industriell använding. READ MORE

  3. 17. Quantum Computing in Nuclear Physics

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Luca Bernecker; [2022]
    Keywords : quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

    Abstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE

  4. 18. Genuine geometric quantum gates induced by non-cyclic geodesic evolution of computational basis

    University essay from Uppsala universitet/Materialteori

    Author : Nils Eivarsson; [2022]
    Keywords : quantum computation; geometric phase;

    Abstract : To reach the error threshold required to successfully perform error-correcting algorithms in quantum computers, geometric quantum gates have been considered because of their natural resilience against noise. Non-cyclic geometric gates have been proposed to reduce the run time of conventional geometric gates, to further guard against decoherence. READ MORE

  5. 19. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors

    University essay from KTH/Tillämpad fysik

    Author : Linnéa Bendrot; [2022]
    Keywords : Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

    Abstract : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. READ MORE

  6. 20. Impact of Noise on the Accuracy of Amplitude Amplification on the IBM Q Quantum Computer

    University essay from KTH/Datavetenskap

    Author : Dilvan Sabir; Edvard All; [2022]
    Keywords : ;

    Abstract : Quantum computers promise immense speed up compared to even the most advanced supercomputers of today, but environmental noise introduces errors in the former, constituting a significant hurdle for realizing these promises. Quantum error-correcting codes have been suggested as a strategy to alleviate this hurdle, including codes optimized toward computation under specific models of noise. READ MORE
