  • Patent number: 12106179
    Abstract: Systems and techniques that facilitate measurement aggregation in quantum programs are provided. In various embodiments, a system can comprise an input component that can access a quantum program. In various instances, the system can further comprise an aggregation component that can aggregate quantum measurement instructions that are listed in the quantum program. In various embodiments, the aggregation component can aggregate the quantum measurement instructions by: identifying a first quantum measurement instruction in the quantum program; identifying another quantum instruction in the quantum program that is adjacent to the first quantum measurement instruction; and swapping and/or merging the first quantum measurement instruction with the another quantum instruction based on determining whether the first quantum measurement instruction and the another quantum instruction share qubits and based on determining whether the another quantum instruction is a quantum measurement instruction.

  • Patent number: 12020122
    Abstract: A method, system and computer program product for mitigating errors in measurements from a quantum system. A discriminator is trained to classify the measurement results of the quantum states of qubits as corresponding to a first quantum state (e.g., quantum state of 0) or a second quantum state (e.g., quantum state of 1). A first region of trust (corresponding to trusted measurements of a first quantum state) with a first discriminator boundary and a second region of trust (corresponding to trusted measurements of a second quantum state) with a second discriminator boundary are defined using the trained discriminator. If a shot-to-shot measurement result of a qubit state falls outside such regions of trust, the measurement result is rejected. In this manner, measurement errors from a quantum system are effectively mitigated, including measurement errors involving shot-to-shot measurement results of the quantum states read from the execution of the quantum circuits.

  • Patent number: 11875224
    Abstract: Systems, computer-implemented methods, and computer program products to facilitate entity steering of a running quantum program are provided. According to an embodiment, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components can comprise a steering component that adjusts at least one parameter corresponding to a running quantum program to define at least one modified parameter. The computer executable components can further comprise an execution component that executes one or more shots of the running quantum program based on the at least one modified parameter.

  • Patent number: 10648832
    Abstract: System, methods, and other embodiments described herein relate to improving situational awareness of occupants of a vehicle. In one embodiment, a method includes analyzing, using at least a processor of the vehicle, scan data from a sensor of the vehicle to detect at least one object within the surrounding environment. The method includes converting the scan data into converted data that represents the at least one object with a reduced quantity of data. The method includes rendering, using the converted data, at least one graphic that is a visual representation of the at least one object. The method includes displaying the at least one graphic within a display of the vehicle at a location within the display that represents a location of the at least one object relative to the vehicle in the surrounding environment.
