International Conference on Quantum Science and Applications (ICQSA-2016)

Abdullah Algin, Md Sadik Hassan Arik, Alexandre M. Gavrilik

This special volume of Journal of Physics: Conference Series is dedicated to the proceedings of "International Conference on Quantum Science and Applications (ICQSA-2016)". The conference was organized by the Centre for Quantum Research and Applications at Eskisehir Osmangazi University, Eskisehir, Turkey. It was held in Eskisehir Osmangazi University Congress and Culture Centre during May 25-27, 2016 http://icqsa2016.ogu.edu.tr . It gathered actively 143 participants from different disciplines in natural and applied sciences coming from 16 different countries from all over the word. It was the first international conference in its content on the scientific research fields of quantum science and applications in Turkey. It also consisted of 12 plenary lectures and 119 contributed oral presentations covering interdisciplinary fields of research. The ICQSA-2016 conference focused on recent modern theoretical and experimental developments of quantum science in multi-disciplinary aspects of areas of mathematics, physics, statistics, chemistry, biology, computer science, electronics, informatics, medicine, education, etc. It served as an interaction platform for students, researchers, public, and private sector delegates for sharing new scientific and technological ideas on quantum applications in science and technology. The topics of the conference were: Quantum theory and quantum computing, quantum information theory and its applications, quantum statistics and its applications, quantum thermodynamics, quantum cryptography, classical and quantum symmetries, quantum calculus in science, engineering, medicine, education, etc., classical and quantum integrable systems, modeling and numerical methods in quantum systems, other modern mathematical methods in science and technology. Each of the submitted papers for this special volume of the proceedings of ICQSA-2016 has been reviewed by external referees. There are 36 accepted papers. Besides, it is worth pointing out that a great deal of interest shown by the participants of the ICQSA-2016 conference gives hope for the continuation of this meeting in the following years. The conference organization was sponsored by Eskisehir Osmangazi University (ESOGU), Eskisehir Tepebasi Municipality, the Scientific and Technological Research Council of Turkey (TUBITAK) under the project number 113F226. Other supporters of this organization were: Eskisehir Metropolitan Municipality, Eskisehir Governorship Provincial Directorate of Culture and Tourism, Pegem Academy Publishing Company. In addition, this special volume is supported by the Scientific and Technological Research Council of Turkey (TUBITAK) under the project number 113F226. Finally, our special thanks go to the Scientific and Organizing Committee members, to the sponsors and supporters, and to all of the participants. We hope this special volume will provide a useful resource for students, experts, and other participants, who are interested in interdisciplinary fields of quantum science and applications.

Radiometry and Few-photon Metrology at the National Research Council of Canada

Angela Gamouras, Andrew D. W. Todd, Éric Côté +4 more

Over the last few years, the National Research Council of Canada (NRC) has been establishing new facilities and improving capabilities in three areas of radiometry: optical power, spectral irradiance, and few-photon measurements. Canada’s realization of the optical radiant power scale now utilizes a new cryogenic electrical substitution radiometer as the primary instrument. With higher cavity absorptance, reduced non-equivalence effects, and a closed-cycle helium cryocooler, this new cryogenic radiometer has significantly contributed to improvements in measurement uncertainties. NRC’s primary spectral irradiance scale has transitioned from a detector based approach to a detector and source based realization. Filter radiometers with spectral responsivity traceable to the cryogenic radiometer and a high temperature blackbody primary light source are implemented in the calibration of transfer standard FEL lamps from 200 nm to 2500 nm. Most recently, NRC has been working to establish a few-photon metrology capability for optical radiometry. The initial goal of this new facility is to measure the detection efficiency of free-space single-photon detectors using a calibrated detector substitution technique. This capability will then be extended to the traceable characterization of NRC on-chip semiconductor quantum dot-based single-photon sources, the evaluation of these sources as new quantum standards, and using entangled photons from these sources for fundamental quantum metrology measurements. Ongoing efforts and details of these new radiometry facilities will be presented.
