Space division multiplexing chip-to-chip quantum key distribution.

Abstract:

:Quantum cryptography is set to become a key technology for future secure communications. However, to get maximum benefit in communication networks, transmission links will need to be shared among several quantum keys for several independent users. Such links will enable switching in quantum network nodes of the quantum keys to their respective destinations. In this paper we present an experimental demonstration of a photonic integrated silicon chip quantum key distribution protocols based on space division multiplexing (SDM), through multicore fiber technology. Parallel and independent quantum keys are obtained, which are useful in crypto-systems and future quantum network.

  • Bridging may help young female Tibetan macaques Macaca thibetana learn to be a mother.

    abstract::Attraction to infants is a common feature of non-human primates. Frequent affiliative male-infant interactions have been observed in many multimale, multifemale groups of macaques, including a behaviour termed 'bridging' in which two male macaques simultaneously lift an infant. This behaviour has been suggested to ser...
