Staging quantum cryptography with chocolate balls

Staging quantum cryptography with chocolate balls

Quantum cryptography is a relatively recent and very active field of research. Its main characteristic is the use of individual particles for encrypted information transmission. Its objective is to encrypt messages or to create and enlarge a set of secret equal random numbers between two spatially separated agents by means of elementary particles, such as single photons, that are transmitted th...

Bertlmann’s chocolate balls and quantum type cryptography

Some quantum cryptographic protocols can be implemented with specially prepared chocolate balls, others protected by value indefiniteness cannot. Similarities and differences of cryptography with quanta and chocolate are discussed. Motivated by these considerations it is proposed to certify quantum random number generators and quantum cryptographic protocols by value indefiniteness. This featur...
