  • Patent number: 12260160
    Abstract: In an integrated circuit (IC) assessment method, an artificial intelligence (AI) component comprising at least one artificial neural network (ANN) is trained to transform layout rendering tiles of a rendering of a reference IC into corresponding reference layout image tiles extracted from at least one layout image of the reference IC. Using the trained AI component, standard cell layout renderings of a library of GDSII or OASIS standard cell layout renderings are transformed into as-fabricated standard cell layout renderings forming a library of as fabricated standard cell layout renderings. Instantiated standard cells and their placements in the layout image of an IC-under-test are identified by matching the instantiated standard cells with corresponding as-fabricated standard cell layout renderings retrieved from the library of as fabricated standard cell layout renderings.

  • Patent number: 12206272
    Abstract: Electric vehicle charging scheduling includes receiving repeated sensor readings of a battery of an electric vehicle, the readings monitoring a charge of the battery while the electric vehicle proceeds along a contemporaneously scheduled route. Then, a geolocation of the electric vehicle is determined and a database queried with the geolocation. A charging station is then identified within geographic proximity of the geolocation of the electric vehicle. As well, a route scheduled for the electric vehicle after the contemporaneously scheduled route is determined. Thereafter, a threshold charge is computed that is requisite to complete both the contemporaneously scheduled route and also at least a portion of the route scheduled after the contemporaneously scheduled route. Finally, in response to a determination that the monitored charge on the battery is below the threshold level, an alert is displayed indicating to charge the battery at the identified charging station.

    Abstract: Methods, systems and apparatus for approximating a target quantum state that is defined as a result of applying a specific rotation operation to an initial quantum state. A method includes determining multiple configurations of T-gates. Each configuration of T-gates includes a number of T-gates that is less than or equal to a predefined total number of T-gates and represents a rotation operation that, when applied to the initial quantum state, produces an evolved quantum state that is an approximation of the target quantum state. A configuration of T-gates that represents a rotation operation with a rotation angle that is closest to a rotation angle of the specific rotation operation is selected from the multiple configurations of T-gates. A rotation operation represented by the selected configuration of T-gates is applied to the initial quantum state to obtain the approximation of the target quantum state.

  • Patent number: 12197834
    Abstract: A method of minimizing a cost function of a quantum computation is provided. The method comprises receiving input of an initial state of a quantum problem instance comprising a Hamiltonian with an associated cost function. The Hamiltonian is converted into a number of Pauli strings, which are used to form an operator pool. The Pauli strings in the operator pool are ranked according to how much they lower a value of the cost function with respect to the initial state. Pauli strings are iteratively added from the operator pool to a parameterized quantum circuit, in a manner to minimize circuit depth, until a variational quantum eigensolver (VQE) algorithm converges to an approximate ground state wave function generated by the parameterized quantum circuit.
