  • Publication number: 20210089693
    Abstract: Computer systems and methods are provided for increasing a rate of simulation for quantum computing devices. A quantum computing device includes a plurality of gates, each of which is coupled to one or more modes. In the provided computer systems and methods, a device definition and state information for the quantum computing device are received. The state information includes a plurality of input patterns, each of which indicates a number of input bosons that correspond to a respective mode of the quantum computing device, and an amplitude that corresponds to each input pattern. The device definition includes a plurality of sets of gate values that indicate modification by a respective gate of an input pattern probability. A first group of input patterns is generated for a first gate. The first group of input patterns includes a subset of the plurality of input patterns that meet grouping criteria.

  • Patent number: 8206232
    Abstract: The amusement apparatus comprising a housing, a frame and an interior space, and a door allowing entry of a player having arms into interior space. An air circulation system fluidly connected to interior space of housing. An engagement system located within interior space. Engagement system, control system, signaling system and an air circulation system are cooperatively interconnected. A player area is located within the interior space and positioned proximate the engagement system wherein contact by player with engagement system initiates a sequence of instructions from the control system to initiate the delivery of air into interior space by air circulation system for circulation of prizes within interior space. A signal to player is sent via signaling system to discontinue player contact with engagement system so player may interact with the prizes circulating in the interior space for the purpose of removing the prizes from the housing via the interior space.

  • Patent number: 4763802
    Abstract: Carbonated beverages in bottles lose their carbonation and become flat once the bottle is opened. In this invention carbonation is preserved and maintained in a simple, inexpensive manner by re-introducing pressure into a bottle which has been opened. A small pump consisting of a cylinder, piston and threaded cap is attached to the top of an opened bottle. This hand operated pump re-introduces pressure to the bottle in the form of compressed air and thus maintains the concentration of carbon dioxide in the liquid regardless of the amount of liquid remaining in the bottle. The pump introduces an air pressure of fifty to sixty pounds per square inch to the bottle which is equivalent to the air pressure found in unopened carbonated beverage bottles at 21 degrees celsius.
