  • Publication number: 20240070514
    Abstract: A quantum memory manager (QMM) of a source endpoint obtains a memory request from a quantum application for quantum memory blocks. The source endpoint negotiates with a destination endpoint to determine a memory lifetime value that includes a minimum decoherence time for qubits stored at the source endpoint and qubits stored at the destination endpoint. The QMM allocates a quantum memory block of a plurality of qubit storage locations to the quantum application based on the memory lifetime value. The QMM receives communication qubits that are entangled with destination qubits sent to the destination endpoint, and stores the communication qubits in the quantum memory block. Each particular communication qubit of the communication qubits is entangled with a particular destination qubit of the destination qubits.

  • Publication number: 20240073010
    Abstract: Disclosed is a method of establishing secure communications between nodes in a cloud environment. The method includes receiving a log-in of a first user, receiving a log-in of a second user and presenting to the first user one or more options to use a secure inter-user communication security service leveraging quantum teleportation in order to communication with the second user, wherein the secure inter-user communication security service optionally uses a quantum EPR processor (QEP). The one or more options include applying the secure inter-user communication security service using QEP to generate EPR Bell state pairs and applying security via quantum teleportation for communications between the first user and the second user and applying the secure inter-user communication security service to securely control communication between a first container associated with the first user and a second container associated with the second user and associated daemons leveraging the QEP.

  • Publication number: 20230370169
    Abstract: A method for routing in a quantum network is provided. The method may include receiving parameters including a fidelity with coherence decay time and an entanglement generation rate for each quantum node in a mesh quantum network by a controller, the controller being configured to communicate with each quantum node of a plurality of quantum nodes in the mesh quantum network. Each quantum node includes a quantum memory and a processor. The method may also include analyzing the fidelity with coherence decay time and the entanglement generation rate to yield a determination of a path fidelity with a path coherence decay time and a path entanglement generation rate between at least one pair of quantum nodes. The method may further include, based on the determination, selecting a quantum communication path from a source node to a destination node.

  • Patent number: 11818257
    Abstract: Disclosed are a system and method of establishing secure communications between nodes in a cloud environment. The method includes receiving a registration of a first user at a quantum processor service provider, receiving at the quantum processor service provider a request for authentication of the first registered user, the request comprising at least the password and the registration number, when the password and registration number match stored data at the quantum processor service provider for the first registered user, generating an EPR entangled pair and transmitting the EPR entangled pair to a first computing device of the first registered user, wherein the first registered user utilizes the EPR entangled pair in order to communicate with a second computing device associated with a second registered user. The quantum processor service provider can include a quantum EPR (Einstein Podoslky and Rosen) processor (QEP) and a logically co-located computer server.
