In today’s quant-ph we find a report of a truly dramatic experiment — one that detected entanglement between Baton Rouge, Louisiana and Givarlais, France. How, you ask: by fiber-optic cable? Satellite? Neither: by postal mail! The authors don’t say if it was FedEx, UPS, or some other carrier that managed to ship half an EPR pair across the Atlantic without decohering it — but whoever it was, that’s who I’m using from now on.
(Note: On close reading, it appears that when the authors use the word “entanglement,” they actually mean “classical correlation.” However, this is a technical distinction that should only matter for experts.)
