Making Lemonade With Quantum Lemons - Science News

Making Lemonade With Quantum Lemons - Science News: "In the laboratory, the researchers arranged two blobs of cesium atoms in separate glass cells. Next, the scientists shot a precisely tuned laser through both clouds of atoms. As the laser excited the cesium atoms, energy left in the form of photons — normally the kiss of death for entangled particles.

But in this case the photons’ departures, carefully calibrated to fill a void in the surrounding electromagnetic field, eventually caused a property of the two atom groups called spin to become entangled."
