  • Patent number: 11507874
    Abstract: A method of sharing address information using quantum states includes storing a number, M, of first qubits in a quantum store at a source node and storing classical information tagged to the M first qubits in a classical store at the source node, where the classical information describes a destination node where the M first qubits share entangled qubits. The M first qubits are measured at the source node and a random number is generated that represents an address of the destination node using the measured M first qubits and the classical information describing the destination node. A packet is sent from the source node that includes the generated random number in a quantum address field and further includes data intended for the destination node in a data field. A number, M, of second qubits is stored in a quantum store at the destination node, wherein each of the M first qubits is entangled with a respective one of the M second qubits.

    Abstract: A method and system for identifying entangled photons includes generating a plurality of sets of four entangled photons, wherein one pair of photons of each set are time correlated, thereby indicating that another pair of four entangled photons are entangled. Quantum metadata comprising a time window corresponding to the generated plurality of sets of four entangled photons is collected. A coincidence of one pair of photons of each of the plurality of the sets of four entangled photons is determined. A state value of at least one photon of the other pair of each of the number of the sets of four entangled photons is determined. Ordered lists of coincidences are compared to ordered lists of state values to determine entangled state information. Time window are compared to times corresponding to the ordered lists. Error conditions are generated if conditions are met.

  • Patent number: 11614771
    Abstract: Method and apparatus for synchronizing and locking clocks identifies entangled pairs of photons by comparing a first and second list of measured state values of single photons, wherein the first list is compiled by photon arrival times measured using a first clock and the second list is compiled by photon arrival times measured using a second clock. Entangled pairs of photons are identified by a match of the measured state values of single photons in their respective lists. Elapsed times of the first and second clocks are determined by taking the difference between arrival times of respective identified entangled pairs of photons measured using their respective clocks. A rate of one of the first and second clocks is changed based on a difference between the elapsed times, thereby synchronizing the first and second clocks. Clocks are locked by repeating.

  • Patent number: 11411658
    Abstract: An entangled quantum state receiver includes an optical detector that generates an electrical signal having a signal characteristic in response to detection of a single photon. A first electrical circuit generates an electrical signal having a predetermined duration at an output when the signal characteristic is present. A clock generates a clock with a period, wherein the predetermined duration is greater than the period. A second electrical circuit generates and stores a state or a time in a memory location, where the state has a first state value when the electrical signal having the predetermined duration is present during a clock cycle and has a second state value when the electrical signal having the predetermined duration is not present during the clock cycle. A processor determines received entangled state information from the state value stored in the memory location or from time stored in the memory location.
