    "abstract": "A continuous variable ping-pong scheme, which is utilized to generate\ndeterministically private key, is proposed. The proposed scheme is implemented\nphysically by using Gaussian-modulated squeezed states. The deterministic way,\ni.e., no basis reconciliation between two parties, leads a two-times efficiency\ncomparing to the standard quantum key distribution schemes. Especially, the\nseparate control mode does not need in the proposed scheme so that it is\nsimpler and more available than previous ping-pong schemes. The attacker may be\ndetected easily through the fidelity of the transmitted signal, and may not be\nsuccessful in the beam splitter attack strategy.",
