Abstract:
A method for suppressing measurement noise in a system having a memory which decays by a characteristic relaxation time, comprising:performing a first measurement on the system to produce a first response indicative of a first state of the system;performing a second measurement on the system after an evolution duration subsequent to said first measurement to produce a second response indicative of a second state of the system, wherein said evolution duration is selected so that the system retains a degree of memory of an aspect of said first measurement when said second measurement is performed; andforming a correlation function including a relation of a first function that has a relation with said first response and a second function that has a relation with said second response,wherein said correlation function is configured to represent information indicative of the system and to reduce at least one component in said first and second responses that adversely affect extracting said information.
