Abstract: Degeneracy in analog processor (e.g., quantum processor) operation is mitigated via use of floppy qubits or domains of floppy qubits (i.e., qubit(s) for which the state can be flipped with no change in energy), which can significantly boost hardware performance on certain problems, as well as improve hardware performance for more general problem sets. Samples are drawn from an analog processor, and devices comprising the analog processor evaluated for floppiness. A normalized floppiness metric is calculated, and an offset added to advance the device in annealing. Degeneracy in a hybrid computing system that comprises a quantum processor is mitigated by determining a magnetic susceptibility of a qubit, and tuning a tunneling rate for the qubit based on a tunneling rate offset determined based on the magnetic susceptibility. Quantum annealing evolution is controlled by causing the evolution to pause for a determined pause duration.

Abstract: A topology or hardware graph of a quantum processor is modifiable, for example prior to embedding of a problem, for instance by creating chains of qubits, where each chain which operates as a single or logical qubit to impose a logical graph on the quantum processor. A user interface (UI) allows a user to select a topology suited for embedding a particular problem or type of problem, to supply parameters that define the desired topology, or to supply or specify a problem graph or problem definition from which a processor-based system determines or selects an appropriate topology or logical graph to impose. Topologies may have regularity and/or self-similarity over the quantum processor or portions thereof, which portions may constitute unit cells. Logical graphs imposed on the quantum processor may take the form of a hypercube graph. A UI allows the user to specify a desired dimension of the hypercube graph.

Abstract: Computational systems implement problem solving using heuristic solvers or optimizers. Such may iteratively evaluate a result of processing, and modify the problem or representation thereof before repeating processing on the modified problem, until a termination condition is reached. Heuristic solvers or optimizers may execute on one or more digital processors and/or one or more quantum processors. The system may autonomously select between types of hardware devices and/or types of heuristic optimization algorithms. Such may coordinate or at least partially overlap post-processing operations with processing operations, for instance performing post-processing on an ith batch of samples while generating an (i+1)th batch of samples, e.g., so post-processing operation on the ith batch of samples does not extend in time beyond the generation of the (i+1)th batch of samples. Heuristic optimizers selection is based on pre-processing assessment of the problem, e.g.

Abstract: A problem graph having one or more odd cycles is embedded in a quantum processor. The quantum processor includes a plurality of qubits and coupling devices, each coupling device operable to provide controllable communicative coupling between a respective pair of the plurality of qubits to form an interconnected topology. Embedding may, for example, be realized by mapping each vertex of the problem graph to a respective single qubit; mapping each edge of the problem graph to a respective single coupling device, where for pairs of qubits, each qubit of the pair is mapped to a respective pair of vertices. The problem graph may include one or more sub-graphs, one or more of the sub-graphs being a bipartite K3,3 graph.

Abstract: Topologies for analog computing systems are provided. Qubits in the topology are grouped into cells, and cells are coupled to adjacent cells by inter-cell couplers. At least some cells are coupled to non-adjacent cells via long-range couplers. Long-range couplers may be arranged into coverings so that certain sets of qubits within a covering region may be coupled with a reduced number of couplers. Each cell within a covering region without a long-range coupler may be proximate to a cell with a long range coupler so that each cell within the covering region is no more than a certain coupling distance away from a long-range coupler. Long-range couplers may couple over a greater physical distance than inter-cell couplers. Long-range couplers may couple to qubits over a larger coupling region, and may extend across multiple crossing regions between qubits.

Abstract: Quantum processor architectures employ unit cells tiled over an area. A unit cell may include first and second sets of qubits where each qubit in the first set crosses at least one qubit in the second set. Angular deviations between qubits in one set may allow qubits in the same set to cross one another. Each unit cell is positioned proximally adjacent at least one other unit cell. Communicatively coupling between qubits is realized through respective intra-cell and inter-cell coupling devices.

Abstract: Dynamic video capture rate control techniques are described. In one or more implementations, a method is described of dynamically controlling video capture rate. Capture of video of a camera is caused by a device to occur at a first rate for a first collection of images in the video. During the causation of the capture of the video at the first rate, an input is detected by the device to change to a second rate that is different than the first rate. Responsive to the detection of the input, the capture rate is changed from the first rate to the second rate, the capture of the video by the camera is caused to occur at the second rate for a second collection of images of the video, and timestamps of the first collection of images or the second collection of images are transformed to configure the image in the video for output at a substantially uniform rate relative to each other.

The substrate provides haptic feedback in response to the event(s). The plasma is capable of accumulating at one or more pockets located in the separation gap, and configured to facilitate the haptic feedback via energy transfer.

Abstract: A computing device has two or more software stacks, each stack simultaneously running a different operating system. Only one enabled operating system at a time has control of hardware resources of the computing device. Each disabled operating system has its device drivers disabled. The drivers may be disabled by stopping device driver messages to devices at a firmware layer unassociated with any operating system. The drivers may be disabled by having their associated operating system dynamically unload them when the operating system is disabled. In some instances, the drivers may be modified to include a “stop” control that tells the driver to stop communicating with its associated device, and a “resume” control that tells the driver to resume communication. When an operating system is disabled, the operating system may send a “stop” message to its device drivers. Drivers associated with messages passed between operating systems may remain enabled.

Abstract: A conferencing service enables users to schedule telecommunication conferences. At the time when the host of a previously scheduled conference joins the conference, one or more participants of the conference do not have active communication sessions with the conferencing service. In response to the host joining the conference, the conferencing service notifies such participants that the conference is starting. Because the conferencing service notifies these participants that the conference is starting, it may be unnecessary for these participants to wait on hold for the host to join the conference.
