Abstract: A computing system including a quantum computing device and a classical computing device. The computing system computes an estimated unitary matrix over a plurality of iterations that each include, at a processor, computing a current-iteration exponent, a current-iteration error parameter, and a conjugate transpose of a current-iteration estimate of the unitary matrix. Each iteration further includes transmitting the current-iteration exponent, the current-iteration error parameter, and the conjugate transpose to the quantum computing device. At the quantum computing device, each iteration further includes computing a process tomography result and outputting the process tomography result to the classical computing device. At the processor, each iteration further includes computing a distance measure between the current-iteration estimate and the process tomography result, and, when the distance measure is below a predefined constant, updating the current-iteration estimate.

The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.

Abstract: Role-based access controls (RBAC) are extended to include multi-party authorizations for certain computing cluster operations or data items. Upon receiving a request to perform an operation over a computing cluster or its data, a check is carried out to determine if the operation (e.g., READ, WRITE, EXECUTE, DELETE, etc.) is subject to both a role-based access control as well as a multi-party authorization (MPA) consensus protocol. The determination to allow or deny the request includes (1) accessing a role-based access control record corresponding to the operation or data item, and (2) invoking the multi-party authorization consensus protocol. Prior to performance of the operation, a computer program collects “approve” or “deny” responses from individual ones of the multiple parties. When approval consensus is reached, the operation is performed. If approval is denied, or if an approval consensus is not reached within a time limit, then the operation is not performed.

Abstract: Methods, systems, and computer program products for thwarting a malware attack. A data storage system stores data items, some of which data items correspond to snapshots. Upon identification of a possible ransomware attack on a data item, the system identifies a version of the snapshot that is not subject to the ransomware attack and seeks to protect the data state of the system from further damage (e.g., due to performance of unauthorized operations on the version of the snapshot that is not subject to the ransomware attack) by requiring consensus from a multi-party authorization (MPA) consensus regime before carrying out requested operations over the snapshot. The MPA consensus regime operates by determining that the operation is subject to a role-based access control (RBAC) as well as a multi-party authorization (MPA) consensus protocol, and then allowing or denying execution of the requested operations based on achieving consensus from among candidate approvers.

Abstract: An identification and authentication scheme maintains control relationships among identities in order to allow a user to dynamically grant or deny permission for a technical support representative to access the user's data, while allowing the user to retain ultimate control over access to the data. Interactions entered by the representative can be distinguished from those entered by the user, while execution paths for representative-entered interactions are configured so that, to an application, the representative-entered transactions appear substantially identical to user-entered transactions. Technical support representatives are thereby able to duplicate users' problems to enable diagnosis and resolution of problems without requiring users to reveal their passwords or login credentials.

Abstract: An access site allows a client application to access a server application on behalf of a subscriber who has an account at the client site. A client application registers with the access site and receives a certificate for the client application. A subscriber is directed to the access site upon an indication that she would like to use the features of the client application that integrate with the server application. The subscriber specifies access rights to the access site, and issues a validation token in association with the specified access rights. When the client site needs the server application to process subscriber data, it forwards the validation token to the access site, using the certificate. The access site validates this information, and where appropriate the server application processes the subscriber data and returns the results to the client application.
