Hi,
On wednesday, I will give a 30 min presentation on interaction-free measurement. This is formally a Probevorlesung for Habilitation at UniZh, but everyone is welcome and I will try to make it interesting for students. Please would you circulate to group members.
Thanks! Prasenjit
Date: Wednesday 9. November Time: 14.00 to 14.30 Room: Irchel 36 J 33

Title: Quantum Bomb Detection
Interaction-free measurement is a quantum paradox: a bomb that explodes if it is struck by a single photon can be detected optically without letting it explode. The paradox was first raised in 1993 by Elitzur and Vaidman, and subsequent work has both improved the theoretical formulation and verified it experimentally. This talk will explain what interaction-free measurement means, suggest a classical analogue, and speculate about applications.
