Two Diamonds Linked by Strange Quantum Entanglement

Scientists have linked two diamonds in a mysterious process called entanglement that is normally only seen on the quantum scale.

Entanglement is so weird that Einstein dubbed it "spooky action at a distance." It's a strange effect where one object gets connected to another so that even if they are separated by large distances, an action performed on one will affect the other. Entanglement usually occurs with subatomic particles, and was predicted by the theory of quantum mechanics, which governs the realm of the very small...

Because energy must be conserved in closed systems (where there's no input of outside energy), the researchers knew that the "lost" energy had been used in some way. In fact, the energy had been converted into vibrational motion for one of the diamonds (albeit motion that is too small to observe visually). However, the scientists had no way of knowing which diamond was vibrating.

Then, the researchers sent a second pulse of laser light through the now-vibrating system. This time, if the light emerged with a color of higher frequency, it meant it had gained the energy back by absorbing it from the diamond, stopping its vibration...

If the two diamonds weren't entangled, the researchers would expect each detector to register a changed laser beam about 50 percent of the time. It's similar to tossing a coin, where random chance would lead to heads about half the time and tails the other half the time on average.

Instead, because the two diamonds were linked, they found that one detector measured the change every time, and the other detector never fired. The two diamonds, it seemed, were so connected they reacted as a single entity, rather than two individual objects.

Yes, you are probably right. I read that in sixth grade. The author at the writing lived a few miles from where I live now, and was associated with Sin John Terrel’s Music Circus iirc she moved to Ireland where at the time she moved income tax was not paid by authors and artists.

That’s a kind of tesseract. Income tax avoidance, that is.

Thanks GOPJ.
