Photonics at the Quantum Limit

• An initiative within the SUPA photonics theme
• Broad Scope includes quantum information, atom
  optics, BEC, quantum communication and metrology,
  single photon generation, classical ! optics, and
  much more.
• Scotlands reputation in photonics relies on
  excellence in optical physics at the most
  fundamental level.

Grand Challenges for Photonics at the Quantum
Limit?

• These are open for discussion at this meeting.
• Examples might be
• Understanding Quantum Theory
• The Quantum to Classical Transition
• Others?
• Photonics is the ideal testbed for these ideas.
  Useful technologies to acquire on the way
  (baby-grand challenges?) might include
• Preparation, control and measurement of photonic
  (and atomic) quantum systems on demand
• Quantum limited metrology
• Quantum imaging techniques
• Robust quantum communication the entangled
  web?
• Quantum information processor?

  the very least) some of the (baby-)grand
  challenges.
