  • Patent number: 11329809
    Abstract: This invention relates generally to a method and system for hybrid classical-quantum communication. The method comprises transmitting a single photon having a particular quantum state over a communication medium using a quantum mode set; and transmitting a classical light beam over the same communication medium using a classical mode set, wherein the classical and quantum mode sets comprise non-separable modes in common. The non-separable modes in common may be two degrees of freedom of a single photon or classical light and may thus be spatial modes in one or more indexes, and polarisation. The invention relates also to a system to implement the method accordingly.

  • Publication number: 20110270780
    Abstract: One or more aspects comprise a computer system comprising one or more servers that: (a) provide a financial personality assessment questionnaire to a user; and (b) receive data describing said user's responses to one or more questions in said questionnaire; and one or more processors in communication with said one or more servers that: (a) based on said data describing said user's responses, assess said user's investment-related attitudes across a plurality of scales and produce a multi-dimensional financial personality identifier for said user; and (b) construct a user risk profile for said user derived from said multi-dimensional financial personality identifier.

  • Patent number: 5768284
    Abstract: The invention features an apparatus and method for detecting recording errors in a telephone network that provides services to a plurality of customers, the method comprising: recording information output by the telephone network relating to the provision of a service to the customers, the information having a periodic pattern; identifying disturbances in the periodic pattern that persist for longer than a predetermined time period; and generating an alarm when the identified disturbances exceed a threshold. Th invention also features using a model to generate a forecast of information that will be output by the network in a time period that has not yet occurred utilizing information recorded during a previous time period, the model including a plurality of states representing disturbances in the periodic pattern, each state representing a disturbance having a different persistence.
