The present invention relates to an apparatus (12) for
processing information by evaluating randomly moving tokens corresponding to particles or quasiparticles, comprising: an input interface (20) for receiving an input
signal; a carrier (22) for supporting a plurality of pathways (30) for the randomly moving tokens and at least one join (32) for connecting two pathways and for permitting a passing of a first token in a
first pathway of the two connected pathways through the join upon presence of a second token from a
second pathway of the two connected pathways in the join; an
insertion unit (24) for inserting tokens into the pathways based on the input
signal; an excitation unit (26) for applying a stimulus to a token in at least one pathway of the plurality of pathways, said stimulus acting to increase the random movement of the token in a direction substantially parallel to the carrier; and an output unit (28) for providing an output
signal based on a location of at least one token after a predefined or dynamically adjusted time period. The present invention further relates to a
sensor system (10) for detecting a physical phenomenon in an environment.
