SYNTHESIS OF A QUANTUM CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18168138 titled 'SYNTHESIS OF A QUANTUM CIRCUIT

Simplified Explanation

The patent application describes systems and methods for synthesizing a quantum circuit. Here are the key points:

  • The system includes a memory and a processor that execute computer executable components.
  • The circuit generation component generates quantum circuits iteratively, starting from 1 to N two-qubit gates.
  • Each iteration adds a single two-qubit gate to the circuits from the previous iteration.
  • The added single-qubit gates represent distinct operations from previous iterations.
  • The circuit identification component identifies a desired circuit that matches a given quantum circuit representation.

Potential applications of this technology:

  • Quantum computing: This technology can be used to efficiently generate quantum circuits, which are essential for performing quantum computations.
  • Quantum simulation: The ability to synthesize quantum circuits can aid in simulating and understanding complex quantum systems.
  • Quantum algorithms: The technology can be used to develop and optimize quantum algorithms for various applications, such as cryptography or optimization problems.

Problems solved by this technology:

  • Circuit synthesis: The technology provides a systematic approach to generate quantum circuits, reducing the complexity and time required for manual circuit design.
  • Optimization: By iteratively adding gates and using distinct operations, the technology aims to find the most efficient circuit representation for a given quantum computation.

Benefits of this technology:

  • Efficiency: The iterative approach allows for the generation of quantum circuits with fewer gates, leading to faster and more efficient computations.
  • Automation: The system automates the process of circuit generation, reducing the need for manual intervention and expertise.
  • Flexibility: The ability to add distinct operations in each iteration provides flexibility in designing circuits for different quantum computations.


Original Abstract Submitted

Systems, computer-implemented methods, and computer program products to facilitate synthesis of a quantum circuit 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 a circuit generation component that generates, iteratively, quantum circuits from 1 to N two-qubit gates, wherein at least one or more iterations (1, 2, . . . , N) adds a single two-qubit gate to circuits from a previous iteration based on using added single -qubit gates that represent operations distinct from previous operations relative to previous iterations. The computer executable components can further comprise a circuit identification component that identifies, from the quantum circuits, a desired circuit that matches a quantum circuit representation.
