Qiskit Qward Project Overview

Qiskit Qward is a framework for analyzing and validating quantum algorithm execution quality on quantum processing units (QPUs). It provides a structured approach for building quantum validators that can be used to assess how well quantum circuits perform on real hardware.

Key Components

The framework consists of several key components:

  1. Scanning Quantum Circuit System:

    • Extends Qiskit’s QuantumCircuit to provide validation and scanning capabilities

    • Handles circuit creation, simulation, and execution on IBM Quantum hardware

    • Provides a standardized interface for implementing quantum validators

  2. Analysis Framework:

    • Processes execution results to extract meaningful insights

    • Includes success rate analysis to evaluate algorithm performance

    • Supports visualization of results for better understanding

  3. Example Implementations:

    • Flip Coin Validator: A simple quantum coin flip example showcasing basic superposition

    • Two Doors Enigma Validator: A more complex validator implementing the quantum solution to the “two doors enigma” puzzle
