By heating calcium in a tantalum oven and subjecting the calcium vapor stream to blue laser, calcium atoms absorb the blue photons and emit two photons of lower energy as they decay twice.
Once they decay from the highest excited state to an intermediate excited state, and then from the intermediate excited state to the lowest energy state.
This double decay creates a pair of entangled photons.
I do not afford maintaining the high temperature needed to vaporize calcium for too long.
So instead, a concentrated water solution of a calcium salt could provide the alternative?
Do I still get entangled photons if I use a laser to excite calcium ions in a solution in water?
