Quantum Fingerprinting: Difference between revisions

Quantum fingerprinting allows two parties (two quantum clients) to collaboratively compute the value of a function using both of their inputs while maintaining the privacy of their own input. The protocol does not permit the two parties to interact directly with each other, hence they send their respective inputs to a trusted third party (quantum server) who computes the correct value of the function corresponding to both inputs while minimizing the amount of information sent by the two parties.  

Minimization of information is done by fingerprinting, which is a technique that associates a string to an exponentially smaller string (fingerprints) such that any two strings can by distinguished solely based on their fingerprints.
