  • Patent number: 11032984
    Abstract: The present invention discloses genes and SNP markers significantly associated with lint percentage trait in cotton, and use thereof. The genes significantly associated with the lint percentage trait in cotton are genes Gh_D05G1124, Gh_D05G0313, and GhWAKL3. In the present invention, a CottonSNP63K gene array is used for genotyping, and genome re-sequencing data are analyzed to identify SNP markers significantly associated with the lint percentage trait in cotton. Moreover, the present invention also discloses use of the genes and SNP markers, which are significantly associated with the lint percentage trait in cotton, in cotton germplasm identification, breeding, or genetic diversity analysis.

  • Patent number: 10078495
    Abstract: A method and an apparatus for generating a source-independent quantum random number are disclosed. The method includes: receiving by a receiver a photon signal sent by a source and converting by the receiver a multi-photon signal contained in the photon signal into a single-photon signal equivalent to the multi-photon signal; modulating a single-photon signal in an X basis or a Z basis, and performing a projection measurement on the X basis or the Z basis randomly; calculating an error rate of the source according to a measurement result of the Z basis; obtaining a partially random binary string according to a measurement result of the X basis; and obtaining and processing a minimal entropy of the partially random binary string so as to obtain a completely random binary string.

  • Patent number: 9294272
    Abstract: A method and system for quantum key distribution (QKD) between a first location and a second location through an intermediate location. The system and method include executing a quantum phase between each of the first and second locations and the intermediate location to determine a first location raw data string at the first location, a first-intermediate raw data string at the intermediate location, a second location raw data string at the second location, and a second-intermediate raw data string at the intermediate location, respectively; calculating, at the intermediate location, announcement data based on a function of the first and second-intermediate raw data strings; announcing, at the intermediary location, the announcement data over a classical channel; and deriving, at each of the first and second locations, a secret key based on the available data and on communications between the first and second locations via a classical channel.
