An experimental tour-de-force: Entanglement between glass bead and light
Getting a glass bead to act like a quantum object by entangling it with light.
Quantum entanglement, a perplexing phenomenon, is not mysterious, ghostly, spooky, or weird. A research team successfully entangled a light beam with a glass bead, a remarkable feat. Entanglement occurs when two objects are linked, correlating their behavior in certain ways. To grasp this concept, consider an arm: both upper and lower limbs are strongly correlated due to their connection at the elbow.
Similarly, two photons can be connected, exhibiting correlations. This connection may seem surprising for two reasons. Firstly, photons are often perceived as independent entities incapable of joining. Secondly, when photons are linked, their correlation is typically limited to energy or polarization.
