  1. DG Few Photon Metrology Report and Discussions Dong-Hoon Lee (KRISS) CCPR WG-SP meeting 8 July 2010, NPL

  2. Aim of the DG • to report the advances and demands in the field of few photon metrology • annual activity report to WG-SP • to discuss upon the outstanding issues in the field of few photon metrology • final report to CCPR WG-SP (after 3 years) recommending the concrete tasks of NMIs for this field

  3. Issues • Is the measurement of photons SI-traceable? • What to do for traceable measurement? • Is the measurement accuracy of photons properly evaluated? • What to do for accuracy improvement? • Can we measure everything what we need? • What to do for better support to application fields? • Is the photon-based definition of “candela” possible? • What to do for realization of a “photon-based scale”? • What else?

  4. Membership • KRISS: Dong-Hoon Lee, Hee-Su Park, Sang-Kyung Choi • INRIM: Maria-Luisa Rastello, IvoDegiovanni, Giorgio Brida • NRC: Joanne Zwinkels, Charles Bamber, Jeff Lundeen • PTB: Stefan Kueck, Gerhard Ulm • NIST: Sergey Polyakov, Alan Migdall, Sae-Woo Nam • NPL: Jessica Cheung • MIKES: ErkkiIkonen • NMIJ: Daiji Fukuda (d.fukuda@aist.go.jp) • Ad-hoc expert members from outside NMIs (invited) • Liaison members from CCEM (Jonathan Williams, NPL)

  5. Activity Proposal • Off-line meeting in conferences and workshops • Single Photon Workshop (2009, 2011, 2013) • NEWRAD (2008, 2011, 2014) • Quantum Workshop in Torino (2008, 2010, 2012) • And more to find in www.photoncout.org • On-line discussion • Exchanging information through a WIKI forum (in preparation)  to combine with www.photoncount.org • Questionnaires on the outstanding issues • Preparation and review of the DG reports • Closing of DG in 2013 by submitting the final report • Follow-up technical TGs for concrete tasks (comparisons, collaborations, etc.)

  6. Status July 2010 • Jan. 2010: Formation of a few photon metrology forum in Korea, supported by KRISS (KRISS, KAIST, POSTECH, PNU) • May 2010: Meeting in Quantum 2010 Workshop, Torino; topics arranged, members invited • A WIKI-site “Few Photon Metrology Forum” in preparation (open soon!) • Next meeting in NEWRAD (Sept. 2011)  Formation of a special session? (1 invited + 5 talks), but to combine with Q-candela project workshop (contact Maria-Luisa)

  7. Scope of Topics • Photon sources • Heralded source based on twin photon generation • Vacancies in diamonds, quantum dots • Photon detectors • Geiger-mode counters (PMT, APD) • Photon-number resolving devices (TES) • Characterization and quantification of photons • Measurement of non-classical properties of light • Calibration of spectral quantum efficiency • Application fields • High-sensitivity imaging (remote sensing, satellite camera, medical imaging, etc.) • Quantum information, quantum computing • Quantum cryptography, quantum communication • Photo-biology, photo-chemistry
