  • Patent number: 12609893
    Abstract: A network device identifies, using a daemon of a userspace of the network device, a packet, and processes, using the daemon, the packet to determine metadata associated with the packet. The network device stores, using the daemon, the metadata and a key value in a data structure. The network device provides, using the daemon, the packet to a kernel of the network device via a virtual interface between the userspace and the kernel, which allows the network device, when using the kernel, to process the packet and to provide the packet to an application of the userspace via a socket. Storing the metadata and the key value in the data structure allows the network device, when using the application of the userspace, to retrieve the metadata from the data structure based on receiving the packet from the kernel via the socket.

  • Publication number: 20260037852
    Abstract: A method, system, and computer program product for performing quantum circuit compilation independent of calibration. A calibration library is created with waveform or pulse generation instructions based on calibration data. A calibration library corresponds to pre-compiled code for the possible gates of the quantum circuit. Such pre-compiled code includes the waveform or pulse generation instructions. Furthermore, transpilation of a quantum circuit into a transpiled object is performed. After compiling the transpiled object into a binary, the calibration library is bound to the binary for execution on a quantum device. In this manner, by being able to compile the quantum circuit without knowing the exact calibration outcome, the requirement to re-compile the quantum circuit, such as when a calibration determines changing the waveform or pulse generation instructions between the compilation and execution of the quantum circuit, is precluded.

  • Publication number: 20250232204
    Abstract: A method, system, and computer program product for implementing noise mitigation in dynamic quantum circuits. A condition in a dynamic quantum circuit is identified. A condition refers to a situation or circumstance used to identify or detect a source of noise in the dynamic quantum circuit that may result in an error occurring in the dynamic quantum circuit. For example, the condition may correspond to the idling times, spectator qubits, and idling qubits in cross-talk resistant states (quantum states and in the dynamic quantum circuit. Based on the identified condition, a context-dependent dynamical decoupling sequence is inserted in the dynamic quantum circuit. A context-dependent dynamical decoupling sequence refers to a dynamical decoupling sequence that is inserted in the dynamic quantum circuit based on the context, such as the occurrence of a particular operation (e.g., mid-circuit measurement, the occurrence of a feed-forward operation, the occurrence of qubit shuttling).
