Presentations

• Introduction to studies (Sandro DOdorico)
• a multi-object, multi-IFU infrared spectrometer
  (Mark Casali)
• CODEX a high resolution spectrograph designed
  to measure the acceleration of the universe
  through precision velocity measurement of
  Lyman-alpha absorbers (Luca Pasquini)
• A mid-IR imager/spectrograph (Ulli Kaeufl)
• SCOWL a sub-mm imager with monolithic arrays
  (Ralf Siebenmorgen)
• an instrument for exploring quantum optical
  phenomena (Bob Fosbury)

Quantum Optics _at_ OWL

• A study of the possibilities for using the unique
  characteristics of OWL to measure quantum optical
  phenomena of interest to (fundamental and)
  astrophysics
• Participants
• Dipartimento di Astronomia, Università di Padova
  (Cesare Barbieri, Fabrizio Tamburini et al.)
• Observatory , Lund University (Dainis Dravins et
  al.)

Outline

• Introduction
• Broad definition of field examples
• Science drivers and advantages of OWL
• QO phenomena of interest in astrophysics
• A Review
• Broad survey of QO phenomena, demonstrating
  relevance to astrophysics and 'cosmological'
  fundamental physics
• Results and experimental possibilities using
  current facilities
• Phenomena requiring OWL - class telescopes for
  their study

5

• Technical requirements and issues
• Instrument and detector characteristics
• Outline of one, or more, potential
  instrumentdetector conceptual designs
• Identification of RD requirements
• Telescope design issues
• Review of the currently anticipated design
  characteristics and interfaces of OWL that are
  particularly pertinent for QO instrument/experimen
  ts
• Is there a case for an OWL QO instrument?

Potential topics (brief!)

• Ultra high time resolution
• Properties of light
• One photon bolometer, interferometer (phase),
  spectrometer
• Two photon quantum spectrometer, intensity
  interferometer, correlation spectrometer
• Multi-photon chaotic light, stable wave,
  Gaussian-scattered chaotic light, anti-bunched
  light
• Photon orbital angular momentum
• Photon entanglement
• Note sensitivity to higher order (n) phenomena
