  1. 1. Entanglement in quantum communication : preparation and characterization of photonic qubits

    Författare :Daniel Ljunggren; Gunnar Björk; Hugo Zbinden; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photonics; Fotonik;

    Sammanfattning : At the heart of quantum physics lies the principle of superposition, and at the heart of information theory lies the bit. Perhaps the most useful property of quantum systems is that they can be loaded with information bits, so-called qubits, that are indefinitely both 0 and 1 until a measurement is made. LÄS MER

  2. 2. Antibody Feedback Regulation : From Epitope Masking to T Helper Cell Activation

    Författare :Andrew Getahun; Birgitta Heyman; Hans-Gustaf Ljunggren; Daniel Conrad; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Immune regulation; B cells; T cells; Antibodies; Fc Receptors; Antigen presentation; Transgenic Knockout Mice; Immunologi; Immunology; Immunologi;

    Sammanfattning : Antibodies have the ability to influence the antibody response against the very antigen they are specific for, in a process called antibody feedback regulation. Depending on the nature of the antigen, the antibody response can be either enhanced or almost completely inhibited. LÄS MER
