A system and method for measuring qubit states. In some embodiments, the system includes a first qubit and a readout circuit, the readout circuit being configured to perform a direct readout of the state of the first qubit.

Techniques for extending blockchain to support controlled branching and consistent data reconciliation for collaborative data evolution include: storing multiple data assets on a global ledger used by multiple nodes in a network; generating a first local cache for a first subset of the multiple nodes; storing, by a node in the first subset, a write transaction to the first local cache; and merging the write transaction from the first local cache onto the global ledger.

A single photon detector based on the kinetic inductance of two-dimensional Van der Waals materials. In some embodiments, a system including such a detector includes: a resonator including a conductive path through a superconducting sheet, the superconducting sheet being composed of a Van der Waals material, the superconducting sheet being configured to absorb a photon, and in response to the absorption of the photon, to exhibit an increase in a kinetic inductance of the conductive path.

This disclosure relates to determining a first bandwidth of one or more first links for one or more nodes in the network; determining a second bandwidth of one or more second links for the one or more nodes; determining that a demand constraint has been met on the network; and determining that a conservation constraint has been met on the network.

A reservoir computer. In some embodiments, the reservoir computer includes a Duffing oscillator, and a readout circuit, and the readout circuit is configured to calculate a plurality of products, each of the products being calculated by multiplying a sample, of a plurality of samples of a signal from the Duffing oscillator, by a respective weight of a plurality of weights.

Systems, devices, methods, and computer-readable media provide resilient space cloud architectures. A device includes a distributed, disrupted, disconnected and denied D4 enabled satellite configured for D4 operations in a mesh network of D4 enabled satellites, the D4 enabled satellite comprising virtual network functions (VNFs), a network virtual function orchestrator (NFVO), and a software defined network (SDN) controller configured for secure VNF-VNF or VNF-ground communications.

Techniques for enforcing trust policies for payload data transmitted through a data provisioning layer include: receiving, by a node in the data provisioning layer, payload data to be delivered to a recipient; obtaining, by the node, a trust policy indicating multiple attributes used to determine trustworthiness of payloads; determining, by the node, a set of values of the attributes associated with the payload data; generating, by the node, a trustworthiness opinion based at least on the trust policy and the set of values of the attributes; transmitting, by the node, the payload data and the trustworthiness opinion via the data provisioning layer toward the recipient; computing, by the recipient, a trustworthiness metric associated with the payload data based at least on the trustworthiness opinion; and determining, by the recipient, an action to take with respect to the payload data based at least on the trustworthiness metric.

A processing circuit for creating a frequency-based output data from sampled streaming analog input data that is provided in K-deep input data blocks where K is a number of samples per clock cycle. The system includes: a memory unit on the single chip to store data including the sampled streaming analog input data; a processing engine on the single chip that receives the incoming streaming data as a series of K-deep input data blocks and performs a portion a frequency transform on the incoming streaming data to produce processed data. The system also includes a memory controller that causes the processed data to initially be stored by column in the memory unit. The memory controller reads data in the memory out in a rotated manner, provides it to the processing engine so that processing engine creates new processed data and writes the new processed data back into the memory.

Techniques are described herein for a messaging system to allow publishers that are aware of the identities of their respective subscribers to target content at those subscribers directly. This may be accomplished by allowing users and other targets (e.g., groups) to register their identities at particular computing nodes of a system. Then publishers (e.g., applications) may send out messages targeted at particular identities, and a publishing system may forward messages to appropriate nodes based on which identities are registered at those nodes. Legacy applications that are not able to target particular identities may instead connect to application adapters that are configured to learn which identities should be targeted by each application. In addition, anonymized identities may be used for application messages that need to cross between domains having differing security levels.

A machine accesses a preexisting set of natural language text documents in multiple natural languages. Each natural language text document in at least a portion of the preexisting set is associated with an event. The machine trains, using the preexisting set of natural language text documents and the associated events, an event encoder to learn associations between texts and event annotations. The event encoder leverages a parser in each of the two or more natural languages. The machine generates, using the event encoder, new event annotations for texts. The machine trains, using the preexisting set of natural language text documents and the new event annotations for the texts generated by the event encoder, an event extraction engine to extract events from natural language texts in the two or more natural languages. The event extraction engine leverages the parser in each of the two or more natural languages.
