  • Publication number: 20240146307
    Abstract: In a general aspect, a quantum logic gate is performed in a quantum computing system. In some cases, a pair of qubits are defined in a quantum processor; the pair of qubits can include a first qubit defined by a first qubit device in the quantum processor and a second qubit defined by a tunable qubit device in the quantum processor. A quantum logic gate can be applied to the pair of qubits by communicating a control signal to a control line coupled to the tunable qubit device. The control signal can be configured to modulate a transition frequency of the tunable qubit device at a modulation frequency, and the modulation frequency can be determined based on a transition frequency of the first qubit device.

  • Patent number: 11863636
    Abstract: Measures for providing timer services in a network including a cluster of nodes responsible for providing timer services to clients. At a given node in the cluster, a request to provide a timer is received from a client. Configuration of a primary replica of the requested timer on a first node in the cluster to pop after a first time has elapsed is initiated. A first timer replication message is transmitted to a second node in the cluster, the first timer replication message indicating that the second node should configure a first backup replica of the requested timer. A second timer replication message is transmitted to a third node in the cluster, the second timer replication message indicating that the third node should configure a second backup replica of the requested timer. Popping of the primary, first backup or second backup timer replicas includes initiating callback of a given client.

  • Publication number: 20230313049
    Abstract: A heat transfer media comprises a particle. The particle comprises a discontinuous phase and a matrix material. The discontinuous phase is disposed within the matrix material, and the matrix material has a higher melting point than the discontinuous phase. The discontinuous phase has a melting point selected to be within a reaction temperature range.

  • Publication number: 20230303932
    Abstract: A reaction process includes introducing hydrocarbon reactants into a vessel, reacting the hydrocarbon reactants in contact with the gas phase catalyst in the vessel to produce reaction products comprising solid carbon and a gas phase product, separating the solid carbon from the gas phase products and the gas phase catalyst to produce a solid carbon product, condensing the gas phase catalyst to produce a condensed catalyst, and returning the condensed catalyst to the liquid catalyst reservoir. The vessel comprises a gas phase catalyst and a liquid catalyst reservoir containing a liquid catalyst.

  • Publication number: 20230099516
    Abstract: A pyrolysis process comprises introducing one or more chemical reactants into a reactor containing a liquid maintained at a high temperature, producing chemical products in the liquid based on the high temperature, allowing the solid product to grow in particle size, accumulating the solid product in the liquid, and removing the solid product from the reactor while retaining a substantial portion of the liquid within the reactor. The chemical products comprise a solid chemical product that is mixed with the liquid.
