  • Patent number: 11611345
    Abstract: A low power sequential circuit (e.g., latch) uses a non-linear polar capacitor to retain charge with fewer transistors than traditional CMOS sequential circuits. In one example, a sequential circuit includes pass-gates and inverters, but without a feedback mechanism or memory element. In another example, a sequential uses load capacitors (e.g., capacitors coupled to a storage node and a reference supply). The load capacitors are implemented using ferroelectric material, paraelectric material, or linear dielectric. In one example, a sequential uses minority, majority, or threshold gates with ferroelectric or paraelectric capacitors. In one example, a sequential circuit uses minority, majority, or threshold gates configured as NAND gates.

  • Patent number: 11587765
    Abstract: A method of reducing reflected Radio Frequency (RF) power in substrate processing chambers may include accessing input parameters for a processing chamber that are derived from a recipe to perform a process on a substrate. The input parameters may be provided to a model that has been trained using previous input parameters and corresponding sensor measurements for the chamber. A predicted amount of reflected RF power may be received from the model and it may be determined whether the predicted reflected RF power is optimized. The input parameters may be repeatedly adjusted and processed by the model until input parameter values are found that optimize the reflected RF power. Optimized input parameters may then be provided to the chamber to process the substrate.

  • Patent number: 11537376
    Abstract: None of the existing quantum programming languages provide specialized support for programming patterns such as conditional-adjoint or adjoint-via-conjugation. As a result, compilers of these languages fail to exploit the optimization opportunities mentioned in this disclosure. Further, none of the available quantum programming languages provide support for automatic translation of circuits using clean qubits to circuits that use idle qubits. Thus, the resulting circuits oftentimes use more qubits than would be required. Embodiments of the disclosed technology, thus allow one to run said circuits on smaller quantum devices. Previous multiplication circuits make use of (expensive) controlled additions. Embodiments of the disclosed technology employ multipliers that work using conditional-adjoint additions, which are cheaper to implement on both near-term and large-scale quantum hardware. The savings lie between 1.5 and 2× in circuit depth for large number of qubits.
