  • Iterative quantum amplitude estimation
    Patent number: 11663511
    Abstract: Systems, computer-implemented methods, and computer program products to facilitate iterative quantum amplitude estimation are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise an iterative quantum amplitude estimation component that increases a multiplier value of a confidence interval in an estimation problem to a defined value that positions the confidence interval in a defined plane of a defined circle. The computer executable components can further comprise a measurement component that captures a quantum state measurement of a qubit in a quantum circuit based on the defined value.
