Quantum Entanglement

Quantum entanglement, a cornerstone of quantum mechanics, plays a pivotal role in emerging quantum technology like computing and cryptography. Qubits, the building blocks of these systems, exhibit entanglement, confounding classical explanations. This experiment focuses on photonic qubits, entangled in polarization. This experiment aims to demonstrate quantum entanglement using photonic qubits and verify nonlocality through Bell inequality violation. Employing the CHSH test criterion, correlation values between spatially separated measurements on entangled photons are measured. Additionally, quantum state tomography will be undertaken, with the entangled state reconstructed through multiple measurements, thus paving the way for advanced quantum information processing.
