Windows QPU Middleware

A Windows-compatible middleware solution for integrating quantum processing units (QPUs) with classical systems. This middleware provides simulation capabilities and interfaces for quantum-classical hybrid computing.

Features

• Windows Service Integration: Runs as a native Windows service
• Quantum Circuit Management: Create and execute quantum circuits
• Pattern Recognition: Quantum-enhanced pattern recognition capabilities
• Optimization: Quantum optimization algorithms
• Error Mitigation: Built-in error correction and mitigation
• Simulation Mode: Test quantum algorithms using Cirq simulator
• Logging System: Comprehensive logging and monitoring

Installation

1. Install required dependencies:

pip install -r requirements.txt

2. Install the Windows service (requires Administrator privileges):

# Run Command Prompt or PowerShell as Administrator
python -m windows_qpu_middleware.windows_service install

Usage

Basic Usage Example

from windows_qpu_middleware import QPUInterface, CircuitManager

# Initialize QPU interface
qpu = QPUInterface()

# Create circuit manager
circuit_manager = CircuitManager(qpu)

# Run pattern recognition
input_data = [0.5, 0.3, 0.8, 0.1]
result = circuit_manager.run_pattern_recognition(input_data)
print(f"Pattern detected: {result['pattern_detected']}")
print(f"Confidence: {result['confidence']}")

Running Tests

python -m windows_qpu_middleware.test_middleware

Service Management (Requires Administrator Privileges)

Install Service

# Run as Administrator
