Controlling Quantum Dynamics Phenomena with Shaped Laser Pulses 
Acting as Photonic Reagents

by Herschel Rabitz (Department of Chemistry, Princeton University)

ABSTRACT

Since the development of the laser some 40 years ago, a long-standing 
dream has been to utilize this special source of radiation to 
manipulate dynamical events at the atomic and molecular scales. 
Hints that this goal may become a reality began to emerge in the 
1990's, due to a confluence of concepts and technologies involving 
(a) control theory, (b) ultrafast laser sources, (c) laser pulse 
shaping techniques, and (d) fast pattern recognition algorithms. 
These concepts and tools have resulted in a high speed instrument 
configuration capable of adaptively changing the driving laser pulse 
shapes, approaching the performance of thousands of independent 
experiments in a matter of minutes.  Each particular shaped laser 
pulse acts as a "Photonic Reagent" much as an ordinary reagent would 
at the molecular scale.  Although a Photonic Reagent has a fleeting 
existence, it can leave a permanent impact.  Current demonstrations 
have ranged from manipulating simple systems (atoms) out to the 
highly complex (biomolecules), and applications to quantum 
information sciences are being pursued.  In all cases, the 
fundamental concept is one of adaptively manipulating quantum 
systems.  The principles involved will be discussed, along with the 
presentation of the state of the field.
