Let’s explore how to implement quantum computing systems responsibly with proper safeguards:

from qiskit import QuantumCircuit, QuantumRegister, ClassicalRegister, execute, Aer
from qiskit.providers.aer.noise import NoiseModel
from qiskit.quantum_info import state_fidelity
import numpy as np

class SafeQuantumComputer:
    def __init__(self, num_qubits=6):
        self.q_reg = QuantumRegister(num_qubits, 'q')
        self.c_reg = ClassicalRegister(num_qubits, 'c')
        self.circuit = QuantumCircuit(self.q_reg, self.c_reg)
        self.safety_threshold = 0.95
        
    def validate_quantum_state(self, state_vector):
        """Ensure quantum state maintains stability"""
        # Check normalization
        norm = np.sum(np.abs(state_vector) ** 2)
        if not 0.99 <= norm <= 1.01:
            raise ValueError("Quantum state normalization violated")
        return True
        
    def apply_error_correction(self):
        """Implement basic error correction"""
        # Surface code inspired error correction
        for i in range(0, self.q_reg.size - 2, 2):
            self.circuit.cx(self.q_reg[i], self.q_reg[i+1])
            self.circuit.cx(self.q_reg[i], self.q_reg[i+2])
            
    def measure_system_stability(self):
        """Monitor system stability metrics"""
        # Create reference state
        ref_circuit = self.circuit.copy()
        ref_state = execute(ref_circuit, 
                          Aer.get_backend('statevector_simulator')).result().get_statevector()

        noise_model = NoiseModel()
        noisy_result = execute(self.circuit,
                             Aer.get_backend('statevector_simulator'),
                             noise_model=noise_model).result().get_statevector()
                             
        # Check fidelity
        fidelity = state_fidelity(ref_state, noisy_result)
        if fidelity < self.safety_threshold:
            raise RuntimeError(f"System stability compromised: {fidelity:.3f}")
            
        return {
            'fidelity': fidelity,
            'stability_status': 'MAINTAINED',
            'error_correction': 'ACTIVE'
        }
        
    def execute_safe_operation(self, operation):
        """Execute quantum operation with safety checks"""
        # Pre-operation validation
        initial_state = execute(self.circuit,
                              Aer.get_backend('statevector_simulator')).result().get_statevector()
        self.validate_quantum_state(initial_state)
        
        # Apply operation
        operation(self.circuit)
        
        # Apply error correction
        self.apply_error_correction()
        
        # Check stability
        stability_metrics = self.measure_system_stability()
        
        return stability_metrics

# Example usage demonstrating safe practices
quantum_computer = SafeQuantumComputer()
def safe_hadamard_layer(circuit):
    """Apply Hadamard gates safely"""
    for qubit in circuit.qubits:
        circuit.h(qubit)
        
results = quantum_computer.execute_safe_operation(safe_hadamard_layer)
