Abstract: In a general aspect, hybrid quantum/classical algorithms are executed in a computing system. A first set of values representing a measurement of a reduced density matrix (RDM) is obtained. The first set of values is based on sampling quantum states generated by a quantum processor. A classical processor generates a second, different set of values to represent the measurement of the RDM. The second set of values is constructed based on the first set of values by a process that imposes one or more n-representability conditions on the second set of values to represent the measurement of the RDM.

Abstract: A terrestrial communication systems, specifically a signal collision avoidance system between a terrestrial transmitter and an airborne receiver, is disclosed. The terrestrial communication system includes an electronic processor configured to determine a receive frequency from a nearby airborne receiver, determine a transmit frequency from a communicatively coupled terrestrial transmitter, and modify the transmit frequency of the terrestrial transmitter based on the determined receive frequency and transmit frequency. To modify the transmit frequency, the electronic processor compares the receive frequency and the transmit frequency to determine a channel type. Based on the determined channel type, including co-channel and adjacent-channel, the electronic processor modifies a spectrum signature of the transmit frequency so that the transmit frequency does not interfere with the receive frequency of the airborne receiver.

Abstract: Metadata is replicated. For instance, in response to receiving a request for replicating metadata to a target node, information of an index structure associated with the metadata is obtained. The index structure may include terminal nodes for storing the metadata and index nodes for storing index information of the terminal nodes. Next, the metadata from the terminal nodes is extracted based on the information of the index structure. Further, a sequence is generated to be replicated of the metadata. The sequence to be replicated includes items of the metadata, and locations of the items in the sequence to be replicated are determined based on key information corresponding to the items. In addition, the items of the metadata, in the sequence to be replicated, are replicated to the target node. In this way, only the metadata in the index structure is replicated, thereby reducing the data amount of replication.

Abstract: According to one embodiment, a first phrase having one or more keywords is received to be added to a phrase blacklist, where the first phrase has been determined to be related to unwanted content. An analysis is performed on the keywords of the first phrase to identifying a set of one or more related phrases that are related to the first phrase. The first phrase and the set of related phrases are added in the phrase blacklist. The phrase blacklist contains a plurality of phrases that have been determined to be related to unwanted content. The phrase blacklist is utilized to prevent a content item from appearing in a search result, in response to a search query having a phrase matching at least one of the phrases in the phrase backlist.

Abstract: A sensitive content display control system determines whether to display sensitive content on a computing device display, such as on a lock screen. The system attempts to authenticate a user of the computing device, and does not display the sensitive content if the user is not authenticated. If the user is authenticated, then the system determines whether anyone in addition to the user is looking at the computing device display. If the user is authenticated and no one else is looking at the computing device display, then the sensitive content is displayed. However, if the user is authenticated and at least one additional person is looking at the computing device display, then the sensitive content is not displayed.
