+}
+```
+
+### Common Error Types
+
+1. **Validation Errors**: Invalid input parameters
+2. **Python Bridge Errors**: CUDA Quantum not available or timeout
+3. **Execution Errors**: Quantum circuit execution failures
+4. **Backend Errors**: Hardware provider connectivity issues
+
+### Error Recovery
+
+- **Timeout Errors**: Increase timeout in configuration
+- **GPU Errors**: Check CUDA installation and device availability

+
+## 🔌 Hardware Provider Setup
+
+### IonQ Configuration
+
+```javascript
+await mcp.callTool('set_quantum_target', {
+  target: 'ionq',
+  configuration: {
+    api_key: process.env.IONQ_API_KEY,
+    backend: 'simulator',  // or 'qpu'
+    shots: 1000
+  }
+});
+```
+
+### Quantinuum Setup
+
+```javascript
+await mcp.callTool('set_quantum_target', {
+  target: 'quantinuum',
+  configuration: {
+    api_key: process.env.QUANTINUUM_API_KEY,

+```
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+#### CUDA Quantum Import Error
+```bash
+Error: CUDA Quantum not available
+Solution: pip install cudaq
+```
+
+#### GPU Not Detected
+```bash
+Error: CUDA device not found
+Solution: 
+1. Check nvidia-smi output
+2. Install NVIDIA drivers
+3. Set CUDA_VISIBLE_DEVICES=0
+```
+
+#### Python Bridge Timeout
+```bash
+Error: Python command timeout
+Solution: 
+1. Increase timeout in config
+2. Check Python path in .env
+3. Ensure CUDA Quantum installation
+```
+
+### Debug Mode
+
+Enable debug logging:
+
+```bash
+export LOG_LEVEL=debug
+npm start
+```
+
+### Testing Connection
+
+```javascript
+// Test platform availability
+await mcp.callTool('get_platform_info');
+
+// Test backend connectivity
+await mcp.callTool('test_backend_connectivity', {
+  backend: 'qpp-gpu'
+});
+```
+
+## 🧪 Testing
+
+Run the test suite:
+
+```bash
+# Unit tests
+npm test
+
+# Integration tests  
+npm run test:integration
+
+# Coverage report
+npm run test:coverage
+```
+
+## 📚 API Reference
+
+### MCP Tool Schema
+
+All tools follow the MCP (Model Context Protocol) specification:
+
+```typescript
+interface MCPTool {
+  name: string;
+  description: string;
+  inputSchema: JSONSchema;
+}
+
+interface MCPToolResult {
+  content: Array<{
+    type: 'text' | 'image' | 'resource';
+    text?: string;
+    data?: string;
+    uri?: string;
+  }>;
+  isError?: boolean;
+}
+```
+
+### Python Bridge API
+
+The Python bridge provides direct access to CUDA Quantum:
+
+```typescript
+class PythonBridge {
+  // Kernel management
+  createKernel(name: string, numQubits: number): Promise<PythonResponse>;
+  applyGate(kernel: string, gate: string, qubits: number[]): Promise<PythonResponse>;
+  
+  // Execution
+  sample(kernel: string, shots?: number): Promise<PythonResponse>;
+  observe(kernel: string, hamiltonian: any[]): Promise<PythonResponse>;
+  getState(kernel: string): Promise<PythonResponse>;
+  
+  // Configuration
+  setTarget(target: string, config?: any): Promise<PythonResponse>;
+}
+```
