  2. 11. Efficient 1.3 mm GaInNAs Quantum Well Lasers for Uncooled, High Speed Operation

    Author : Yongqiang Wei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semiconductor laser; uncooled; temperature dependence; modulation; quantum well; molecular beam epitaxy; high speed; GaInNAs;

    Abstract : The rapid expansion of tele and data transmission systems requires an ever increasing capacity in modern optical fibre communication networks. With the implementation of short distance, high density networks, such as access networks, there is a need for cost-effective optical transmitters compatible with single mode fibres. READ MORE

  4. 12. Quantum error correction

    Author : Jonas Almlöf; Gunnar Björk; Marcin Swillo; Jan-Åke Larsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : Quantum error correction is the art of protecting quantum states from the detrimental influence from the environment. To master this art, one must understand how the system interacts with the environment and gives rise to a full set of quantum phenomena, many of which have no correspondence in classical information theory.

  5. 13. All-Fiber System for Photonic States Carrying Orbital Angular Momentum : A Platform for Classical and Quantum Information Processing

    Author : Alvaro Alarcón; Guilherme B. Xavier; Sebastião de Pádua; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quantum Communication; Optical communication; Orbital Angular Momentum; Photonic Lantern; Few-mode-fibers;

    Abstract : The protection of confidential data is a fundamental need in the society in which we live. This task becomes more relevant when observing that every day, data traffic increases exponentially, as well as the number of attacks on the telecommunication infra-structure. READ MORE

  6. 14. Theory of electronic structure and transport in heterostructure nanowires

    Author : Florinda Viñas Boström; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electronic structure; electron transport; nano; quantum; InAs; GaSb; topological; nanowires; quantum dots; Fysicumarkivet A:2020:Vinas Boström;

    Abstract : Today, semi-conductor nanowires can be grown with very high precision, using epitaxy. This allows for studies of new nanowire-based quantum devices, likely to be part of novel quantum technologies in the future. This thesis concerns nanostructures based on InAs nanowires. READ MORE

  7. 15. CUnT-SPLICING THOUGHT-FORMS : Promiscuous Play with Quantum Physics and Spirituality

    Author : Lea Porsager; Konsthögskolan i Malmö; []
    Keywords : HUMANIORA; HUMANITIES; Artmaking; Excited states; Rope-work; Thought-Forms; Agential realism; Quantum mysticism; Tantra;

    Abstract : CUnT-SPLICING THOUGHT-FORMS — Promiscuous Play with Quantum Physics and Spirituality could perhaps best be described as an invocation of excited states. In more ways than one, this dissertation indulges in a weird threesome between quantum thinking, tantric practices, and feminist theory, with artistic practice at its core. READ MORE
