Have fullerene molecules been (quantum) entangled yet?

have fullerene molecules (buckyball) been (quantum) entangled yet?

What kind of entanglement are you talking about?

In the broadest sense you could say they get entangled all the time, since they interact with each other and with surfaces through dispersion forces, which could be consideded a form of entanglement.

agreed alxm.

i was referring to the kind of entanglement what is generated by having one photon strike a BBO crystal and when two photons with half the wavelength/frequency (?) emerge from the other end of the BBO.

the energy of the single photon has been transferred to two photons with half the energy each.

these photons are now entangled with opposite spins
