  • Patent number: 11392848
    Abstract: A qubit assembly includes a first superconducting loop comprising a first Josephson junction and a second Josephson junction, a second superconducting loop comprising the second Josephson junction and a third Josephson junction, and a third superconducting loop comprising the third Josephson junction and a fourth Josephson junction. A flux source is configured to provide a control flux to the second superconducting loop, such that the effective commutation relations between a first quantum operator corresponding to current in the first superconducting loop and a second quantum operator corresponding to current in the third superconducting loop can be changed by changing a magnitude of the control flux provided to the second superconducting loop by the flux source.

  • Publication number: 20190043380
    Abstract: Example methods, apparatuses, and systems (e.g., machines) are presented for a gamification platform that is the first automated, machine-based system to seamlessly integrate and deliver personalized remediation, centralized learning resources, experiential learning labs, peer and mentor collaboration, immersive scenario-based story, gamified scoring, and real-time heuristics to a user in a learning and training environment. In some embodiments, the gamification platform may be configured to ingest pre-existing training material or other teaching curricula and create an interactive gaming program around the exercise of the training material by a user.

  • Patent number: 8495159
    Abstract: Accessing, via an end user device, email messages of an external mail source. A direct access proxy is operative to reconcile the email contents of external email sources with the email contents of user devices through the use of lists of unique email identifiers (UIDs). A Partition Database returns UID lists reflective of the UIDs of email messages previously received from the external email source and forwarded to a network server of the system (forwarded UID lists). A memory cache external to the direct access proxy and its corresponding Partition Database returns forwarded UID lists. The direct access proxy determines the data reliability of the Partition Database and memory cache, and obtains forwarded UID lists from the memory cache when it determines that the memory cache is at least as reliable as the Partition Database.

  • Patent number: 8468204
    Abstract: A communications system may include a client device for generating email processing jobs and a proxy server communicating asynchronously over the Internet with the client device for processing the email processing jobs. The client device may post a given email processing job to the proxy server with a unique job identifier (ID), and the proxy server thereafter may post job results for the given email processing job to the client device also with the unique job ID. The client device may also advantageously post at least one other email processing job to the proxy server over the Internet at a time between posting the given email processing job and receiving the job results therefor.
