Abstract
Systems, apparatuses, methods, and computer program products are disclosed for establishing cryptographic keys shared among three or more devices. An example method includes generating a set of particles and an entangled particle triplet based on the set of particles. The example method further includes transmitting the first set of entangled particles to a first host device, the second set of entangled particles to a second host device, and the third set of entangled particles to a third host device, and making a determination whether the three sets of bits are matching, where the three sets of bits are derived from the three sets of entangled particles sent to the three host devices. The example method further includes establishing the cryptographic keys based on the matching sets of bits.
