  • Monte Carlo Markov chain based quantum program optimization
    Patent number: 11651232
    Abstract: From a quantum program a first mutant is generated using a processor and a memory, where the first mutant is a randomly-generated transformation of the quantum program. A quality score, a correctness distance, and a probability of acceptance corresponding to the first mutant are computed. An acceptance corresponding to the first mutant is determined according to the probability of acceptance. Upon determining that an acceptance of the first mutant corresponding to the probability of acceptance exceeds an acceptance threshold, the quantum program is replaced with the first mutant. Upon determining that the quality score exceeds a storage threshold and that the correctness distance is zero, the first mutant is stored. These actions are iterated until reaching an iteration limit.

  • Method of double-side polishing wafer
    Patent number: 11648640
    Abstract: Provided is a method of double-side polishing a wafer by which variations of the GBIR values of polished wafers between batches can be reduced. In the method of double-side polishing a wafer, a current batch includes measuring the center thickness of the wafer before polishing (S100); setting a target GBIR value within a predetermined range (S110); calculating a polishing time of the current batch based on Formula (1) (S120); and polishing both surfaces of the wafer for the calculated polishing time (S130). Polishing time of current batch=polishing time of previous batch+A1×(center thickness of wafer before polishing in previous batch?center thickness of wafer before polishing in current batch)+A2×(GBIR value of wafer after polishing in previous batch?target GBIR value)+A3??(1), where A1, A2, and A3 are predetermined coefficients.

  • Generating artistic designs encoded with robust, machine-readable data
    Patent number: 11651469
    Abstract: Artwork carrying machine readable data is generated by editing artwork according to a data signal or transforming the data signal into artwork. The machine-readable data signal is generated from a digital payload and converted into an image tile. Artwork is edited according to the image tile by moving graphic elements, adapting intersections of lines, or altering line density, among other techniques. Artwork is generated from the data signal by skeletonizing it and applying morphological operators to a skeletal representation, such as a medial axis transform. Artistic effects are introduced by filtering the data signal with directional blurring or shape filters.
