東京大学工学部計数工学科 システム情報談話会

日時: 2008年11月17日(月) 15:30-17:30

場所: 東京大学本郷キャンパス工学部6号館3階367号室(セミナー室A・D)

講演者: Dr Mazyar Mirrahimi (INRIA)

講演題目: Real-time synchronization feedbacks for single-atom frequency
standards

概要:
Simple feedback loops, inspired from extremum-seeking, are proposed to
lock a probe frequency to the transition frequency of a single quantum
system following quantum Monte-Carlo trajectories. The quantum system,
in study, corresponds to a 3-level one that appears in coherence
population trapping and optical pumping. For this systems, the feedback
algorithm is shown to be convergent in the following sense: the probe
frequency converges in average towards the system-transition one and its 
standard deviation can be made arbitrarily small. Closed-loop
simulations illustrate robustness versus jump-detection efficiency and
modeling errors.
