Entanglement Swapping and Quantum Correlations via Symmetric Joint Measurements
Entanglement Swapping and Quantum Correlations via Symmetric Joint Measurements
We use hyper-entanglement to experimentally realize deterministic entanglement swapping based on quantum Elegant Joint Measurements. These are joint projections of two qubits onto highly symmetric, iso-entangled, bases. We report measurement fidelities no smaller than $97.4\%$. We showcase the applications of these measurements by using the entanglement swapping procedure to demonstrate …
