If the monitoring type indicates a negated state of the interrupt signal, the interrupt monitoring circuit monitors the negated state. If a second duration of the continuous negated state exceeds the second monitoring period, the interrupt monitoring circuit detects the state as a failure.

A quantum processor performs input and output which may be performed synchronously. The quantum processor executes a problem to generate a classical output state, which is read out at least partially by an I/O system. The I/O system also transmits a classical input state to by the I/O system, which may include the same qubit-proximate devices used for read-out. The classical input state is written to the qubits, and the quantum processor executes based on the classical input state (e.g., by performing reverse annealing to transform the classical input state to quantum state).

Responses of software applications to spatiotemporal events can be tested using simulated environments. In one example, a system can generate a simulated environment having simulated distributed devices positioned at various spatial locations in the simulated environment. The system can then simulate a spatiotemporal event propagating through the simulated environment by modifying a device simulation property of each simulated distributed device based on the spatiotemporal event and a respective spatial location of the simulated distributed device in the simulated environment. This can produce simulation outputs impacted by the spatiotemporal event. The system can then provide the simulation outputs as input to a target software application to test a response to the spatiotemporal event by the target software application.

A cloud traffic migration system may be used to counter suspected harmful traffic. For example, a virtual machine (VM) may have a separate security and networking policy called a VM shell. The VM shell may be placed at the VM's interface as a layer of protection. When suspected harmful traffic is detected inside the VM, multiple mini VMs may be created that replicate some functions of the infected VM and the traffic may be grouped and segregated into categories. Each category of traffic may be routed to a mini VM for further analysis. Any traffic confirmed to be harmful may be kept inside the mini VM and subject to restrictive rules. Such restrictive rules may introduce delays to waste the attackers time or resources as well as obtain data for threat analytics.
