2. 1. Strong Interaction Between a Single Artificial Atom and Propagating Microwave Photons

   Author : Io Chun Hoi; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave devices; Mollow triplet.; qubit; circuit QED; electromagnetically induced transparency; quantum nodes; transmon; quantum channels; superconductivity; anomalous dispersion; quantum information; microwaves; quantum network;

   Abstract : The realization of a quantum network composed of quantum nodes which process quantum fields and quantum channels to transfer quantum information has recently been proposed. In recent years, fundamental experiments produced by superconducting circuits suggest that they are promising candidates for realization of a quantum network. READ MORE

4. 2. Experimental multiuser secure quantum communications

   Author : Jan Bogdanski; Mohamed Bourennane; Nobuyuki Imoto; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum key distribution; multiparty quantum secret sharing; Sagnac interferometer; “plug play” QKD; Passive Optical Network PON ; decoy states; single mode fiber birefringence compensation; quantum bit error rate; visibility; Physics; Fysik; fysik; Physics;

   Abstract : 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.

5. 3. Integrated Photonics for Quantum Optics

   Author : Samuel Gyger; Val Zwiller; Stephan Steinhauer; Ali W. Elshaari; Marijn A. M. Versteegh; Matthew D. Shaw; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; integrated photonics; single-photons; single-photon sources; quantum dots; single-photon detectors; SNSPD; integrerad fotonik; enstaka fotoner; enstaka fotonkällor; kvantprickar; enstaka fotondetektorer; SNSPDs; Optics and Photonics; Optik och fotonik; Physics; Fysik;

   Abstract : Quantum physics allows us a vision of Nature's forces that bind the world, all its seeds and sources. After decades of primarily scientific research, we've arrived at a stage in time where quantum technology can be applied to practical problems and add value outside the field. READ MORE

6. 4. Efficient and Reliable Simulation of Quantum Molecular Dynamics
