  2. 1. Realistic prospect for continuous variable quantum computing in circuit-QED

    Author : Ingrid Strandberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Continuous variable quantum computing; quantum supremacy; quantum state engineering; negative Wigner function; quantum advantage;

    Abstract : This licentiate thesis is an extended introduction to the appended papers, which pertain to finding quantum states that are useful for continuous variable quantum computing. The useful states are characterized by a negative Wigner function. READ MORE

  4. 2. Gaussian conversion protocols forcubic phase state generation

    Author : Yu Zheng; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Continuous variables; Cubic phasestate; Quantum computing; Universality; Gaussian protocols;

    Abstract : This licentiate thesis will introduce the background of the appended paper. The scope of this thesis is to find a Gaussian conversion protocol that allows one to prepare cubic phase states, which are resourceful states for achieving universality in continuous-variable quantum computation.

  5. 3. 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

  6. 4. Degenerate and nondegenerate Josephson parametric oscillators for quantum information applications

    Author : Andreas Bengtsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum information; superconducting circuits; multimode; circuit quantum electrodynamics; SQUID; Parametric oscillations;

    Abstract : Parametric oscillations are well studied phenomena, with applications in amplification, quantum optics, and quantum information processing. They can occur as a parameter of a system, such as the resonant frequency, is being modulated or “pumped” by an external field. READ MORE

  7. 5. Building a Bosonic Microwave Qubit

    Author : Marina Kudra; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D cavity; qubit; cubic phase state; continuous variable; circuit QED; bosonic codes; GKP-state; superconducting circuits;

    Abstract : Superconducting circuits is a promising platform for quantum computing. Quantum information is usually stored in discrete two-level qubits e.g. in transmon qubits. READ MORE
