  2. 1. Representation of Quantum Algorithms with Symbolic Language and Simulation on Classical Computer

    Author : Peter Nyman; Andrei khrennikov; Paul Fischer; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Deutsch-Josza algorithm; Grover s algorithm; Quantum computing; Quantum error-correcting; Shor s algorithm; Simon s algorithm; Simulation of quantum algorithms; Deutsch-Josza algoritm; Grovers algoritm; Kvantdatorer; kvantmekanisk felrättande kod; Shors algoritm; Simons algoritm; Simulering av kvantdatorer; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Abstract : Utvecklandet av kvantdatorn är ett ytterst lovande projekt som kombinerar teoretisk och experimental kvantfysik, matematik, teori om kvantinformation och datalogi. Under första steget i utvecklandet av kvantdatorn låg huvudintresset på att skapa några algoritmer med framtida tillämpningar, klargöra grundläggande frågor och utveckla en experimentell teknologi för en leksakskvantdator som verkar på några kvantbitar.

  4. 2. On relations between classical and quantum theories of information and probability

    Author : Peter Nyman; Andrei Khrennikov; Sergei Kozyrev; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Born’s rule; Clifford algebra; Deutsch-Josza algorithm; Grover’s algorithm; Hyperbolic interferences; Inverse Born’s rule problem; Probabilistic data; Quantum computing; Quantum error-correcting; Quantum-like representation algorithm; Shor’s algorithm; Simon’s algorithm; Simulation of quantum algorithms; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Abstract : In this thesis we study quantum-like representation and simulation of quantum algorithms by using classical computers.The quantum--like representation algorithm (QLRA) was  introduced by A. Khrennikov (1997) to solve the ``inverse Born's rule problem'', i.e. READ MORE

  5. 3. Dynamical Analysis of Terahertz Quantum Cascade Lasers

    Author : Denizhan Ekin Önder; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terahertz; quantum cascade lasers; electric field domains; chaos; simulation; Fysicumarkivet A:2023:Önder;

    Abstract : This thesis focuses on various aspects in terahertz quantum cascade lasers such as high temperature performances, electrical instabilities and chaos. In the first part of the thesis, an introduction to the topic and the non equilibrium Green's function package applied is given with particular emphasise on the inhomogeneous domain model and the chaos theory.

  6. 4. Multiparty Quantum Communication and fs-laser Written Integrated Optics Circuits

    Author : Ashraf Mohamed El Hassan; Mohamed Bourennane; Guillermo Andler; Marcos Curty; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum optics; quantum communication; quantum cryptography; fs-laser written waveguides; integrated optics circuits; Physics; fysik;

    Abstract : Quantum information science, the rapidly developing interdisciplinary field,  gives power to the information and communications technologies (ICT) by  providing secure communication, precision measurements, ultra-powerful simulation and ultimately computation. It is well known that photons are an ideal candidate for encoding the quantum bit, or "qubit", in quantum information and specially for quantum communication. READ MORE

  7. 5. Computational Ecotoxicology

    Author : Sergio Manzetti; David Van der Spoel; Janez Mavri; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pollutants; simulation; molecular; dynamic; quantum; chemistry; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : Human society has progressed by polluting ecosystems since at least the early industrial revolution. Large amounts of harmful chemical compounds have been dispersed in soils, seas, ground waters and wildlife habitats by industrial and anthropomorphic activities over the last two centuries, leading to a persistent toxicological load on the environment.
