A research team at the National Research Council Canada (Ottawa) has developed a method of using laser pulses to control quantum processes.

The method, described in the October 13 issue of Science, was illustrated by changing the outcome of a chemical reaction.

According to Albert Stolow, the NRC team leader, the tool could be used to directly encode nanoscale information or control nanoscale switches.

Another application is in developing novel forms of optical microscopy of live cells, where quantum control methods can be used to sharpen images, enhance sensitivity and perhaps perform nanoscale surgery on individual cells.
