  1. 11. Continuous Quantum Control of Quantum Dot Systems

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

    Author : Daniel Holst; [2022]
    Keywords : Quantum Control; Quantum Fokker-Planck Master Equation; Maxwell s demon; Quantum dots; Full counting statistics; Generalized Quantum Measurements; Thermodynamics; Physics and Astronomy;

    Abstract : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. READ MORE

  3. 12. Implementing two-qubit gates along paths on the Schmidt sphere

    University essay from Uppsala universitet/Materialteori

    Author : Max Johansson Saarijärvi; [2022]
    Keywords : Quantum; Physics; Quantum physics; Quantum information; Quantum computers; Quantum computation; qubit; quantum gate; geometric quantum computation; GQC; quantum decoherence; Kvantfysik; Kvantdatorer; Kvantinformation; kvant; kvantberäkning; kvantgrind;

    Abstract : Qubits (quantum bits) are what runs quantum computers, like a bit in classical computers. Quantum gates are used to operate on qubits in order to change their states. As such they are what ”programmes” a quantum computer. READ MORE

  4. 13. 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

  5. 14. 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

  6. 15. Folding HP Proteins on a Quantum Annealer

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Lucas Knuthson; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. READ MORE
