Systems and methods for quantum-secured, private-protected computations

摘要

Systems and methods for quantum-secured, private-protected computations The present invention relates to a method for secure computation and/or communication. The entangled photons 118 are generated such that each participating party receives a series of light pulses. Each party has private information 110 , 112 that is not transmitted over public or private communication channels. Instead, each party transforms its respective private information 110 , 112 into measurement bases via an encryption process 114 , 116 that is then applied to the entangled photons 118 . After the measurement process, e.g., quantum frequency transformation (122, 124), reference indices (124, 126) are published (128) so that the calculation can be performed without directly or indirectly exposing private information.
