  2. 1. Machine learning for quantum information and computing

    Author : Shahnawaz Ahmed; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quantum machine learning; quantum process tomography; quantum information; Machine learning; generative neural networks; variational quantum algorithms; quantum state tomography; optimization; quantum computing; Bayesian estimation;

    Abstract : This compilation thesis explores the merger of machine learning, quantum information, and computing. Inspired by the successes of neural networks and gradient-based learning, the thesis explores how such ideas can be adapted to tackle complex problems that arise during the modeling and control of quantum systems, such as quantum tomography with noisy data or optimizing quantum operations, by incorporating physics-based constraints.

  4. 2. For a Fistful of Qubits: Computational Quantum Chemistry on Near-Term Quantum Computers

    Author : Mårten Skogh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonadiabatic processes; quantum error mitigation; variational quantum algorithms; quantum computation; computational chemistry;

    Abstract : Quantum computing has been touted as a great new frontier of computation, pushing the limits of what we consider within reach of computation. While not all problems are expected to be efficiently solved by a quantum computer, quantum chemistry is among those where many have speculated on near-term quantum advantage. READ MORE

  5. 3. Variational Methods in Combinatorial Optimization and Phylogeny Reconstruction

    Author : Henrik Jönsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; annealing; variational; mean-field; phylogeny; constraint satisfaction; combinatorial optimization; maximum likelihood; Physics; Fysik; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2001:Jönsson; Matematisk och allmän teoretisk fysik; thermodynamics;

    Abstract : Algorithms based on the variational approach, as used in statistical physics, are developed. For constraint satisfaction problems a novel cost function, based on information-theoretic arguments, is introduced, and an algorithm similar to the mean-field annealing algorithm is proposed.
