    "abstract": "By analogy to classical cryptography, we develop a \"quantum public key\" based\ncryptographic scheme in which the two public and private keys consist in each\nof two entangled beams of squeezed light. An analog message is encrypted by\nmodulating the phase of the beam sent in public. The knowledge of the degree of\nnon classical correlation between the beam quadratures measured in private and\nin public allows only the receiver to decrypt the message. Finally, in a view\ntowards absolute security, we formally prove that any external intervention of\nan eavesdropper makes him vulnerable to any subsequent detection.",
