Very happy about this new PRL paper! 🥳
It's an experiment of an AI-discovered idea that was overlooked for 25+ years:
An alternative to entanglement swapping for entangling two independent photons - without (!) using entanglement or Bell state measurements.

We then realized that PyTheus’s solution actually entangles two distant particles without starting from entanglement, without BSM & even without measuring all ancillary photons.
For me, this changed my perspective on what is necessary to create entanglement—not because I now know what is necessary, but because I’ve realized what is not.
Beautifully implemented by the group of Xiaosong Ma at Nanjing University.
