   Sammanfattning : We are currently experiencing a rapid development of quantum information, a new branch of science, being an interdisciplinary of quantum physics, information theory, telecommunications, computer science, and many others. This new science branch was born in the middle of the eighties, developed rapidly during the nineties, and in the current decade has brought a technological breakthrough in creating secure quantum key distribution (QKD), quantum secret sharing, and exciting promises in diverse technological fields.

3. 2. Photonic Qubits for Quantum Communication : Exploiting photon-pair correlations; from theory to applications

   Författare :Maria Tengner; Anders Karlsson; Alexei Trifonov; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum communication; photon-pair sources; entanglement; Physics; Fysik;

   Sammanfattning : For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. LÄS MER
