  2. 1. Application of the quantum approximate optimization algorithm to combinatorial optimization problems

    Author : Pontus Vikstål; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; combinatorial optimization; quantum computing; Quantum approximate optimization algorithm;

    Abstract : This licentiate thesis is an extended introduction to the accompanying papers, which encompass a study of the quantum approximate optimization algorithm (QAOA). It is a hybrid quantum-classical algorithm for solving combinatorial optimization problems and is a promising algorithm to run on near term quantum devices. READ MORE

  4. 2. The quantum approximate optimization algorithm: optimization problems and implementations

    Author : Pontus Vikstål; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantum approximate optimization algorithm; quantum computing; error mitigation; cat qubits;

    Abstract : This thesis explores the Quantum Approximate Optimization Algorithm (QAOA), a hybrid classical-quantum algorithm designed to solve combinatorial optimization problems. The goal of this algorithm is to iteratively optimize a variational state to approximate the ground state of a cost Hamiltonian that encodes a combinatorial optimization problem. READ MORE

    Author : David Fitzek; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; variational quantum algorithm; Quantum computing; quantum approximate optimization algorithm; vehicle routing;

    Abstract : Quantum computing offers new heuristics for combinatorial problems. With small- and intermediate-scale quantum devices becoming available, it is possible to implement and test these heuristics on small-size problems. READ MORE

  6. 4. Quantum information processing with tunable and low-loss superconducting circuits

    Author : Andreas Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; parametric modulation; quantum information; high coherence; superconducting circuits; circuit quantum electrodynamics;

    Abstract : The perhaps most promising platform for quantum information processing is the circuit-QED architecture based on superconducting circuits representing quantum bits. These circuits must be made with low losses so that the quantum information is retained for as long as possible. READ MORE
