About: Quantum fingerprinting

An Entity of Type: topical concept, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Quantum fingerprinting is a proposed technique that uses a quantum computer to generate a string with a similar function to the cryptographic hash function. Alice and Bob hold -bit strings and . Their goal and a referee's is to obtain the correct value of . To do this, quantum states are produced from the fingerprints and sent to the referee who performs the Swap test to detect if the fingerprints are similar or different with a high probability.

  • Quantum fingerprinting is a proposed technique that uses a quantum computer to generate a string with a similar function to the cryptographic hash function. Alice and Bob hold -bit strings and . Their goal and a referee's is to obtain the correct value of . To do this, quantum states are produced from the fingerprints and sent to the referee who performs the Swap test to detect if the fingerprints are similar or different with a high probability. If unconditional guarantees of security are needed, and if it is impractical for the communicating parties to arrange to share a secret that can be used in a , this technique might one day be faster than classical techniques given a quantum computer with 5 to 10 qubits. However, these circumstances are very unusual and it is unlikely the technique will ever have a practical application; it is largely of theoretical interest. (en)
