DG Few Photon Metrology

Report and Discussions

Dong-Hoon Lee (KRISS)

CCPR WG-SP meeting

8 July 2010, NPL

aim of the dg
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
issues
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?

activity proposal
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.)
status july 2010
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)
