Seminars
Seminars are held approximately every second
Friday at 3:30pm.
Refreshments are served
half an hour before the seminar in the SOLL coffee room, level 1,
Applied Sciences Building, corner Burwood Road and Serpells Lane.
There is an opportunity for attendees to meet the speaker at this
time.
Forthcoming Seminars:
Quantum Teleportation of Light and the Laser Quantum State
Professor Howard Carmichael
University of Auckland, New Zealand
Monday 24 November 2008, 3:30 pm
EN101 (Ground Floor, EN Building), Hawthorn.
In this talk we explore
two loosely connected topics, unified by the theme of entanglement
and its interpretation. The first concerns the quantum teleportation
of light. We review recent experiments on continuous variable teleportation
and ask whether their strategy (protocol) can teleport a beam of
light, i.e, across its entire bandwidth...by extension of its temporal
correlations. The second follows from the assertion that genuine
continuous variable teleportation cannot be achieved by conventional
laser sources [Rudolf and Sanders, PRL 87, 077903 (2001)], since
according to Moelmer [PRA 55, 3195 (1997)] "optical coherences
may be regarded as a convenient fiction". We explore an argument
in opposition...that from an understanding of entanglement itself,
optical coherence is closer by far to fact than it is to a fiction.
