The Ghost of Quantum Entanglement

I’m a bit of a quantum guy, but is an area that does not make the press that often.  So I was quite happy when I came across an article online as Scientific American about about the possibility of quantum entanglement last past the point of entanglement destruction. “Spooky action at a distance” is how Albert Einstein described quantum entanglement.

quantum physicist Seth Lloyd of the Massachusetts Institute of Technology suggests that memories of entanglement can survive its destruction. He compares the effect to Emily Brontë’s novel Wuthering Heights: “the spectral Catherine communicates with her quantum Heathcliff as a flash of light from beyond the grave.”

If proved out this would have implications for quantum cryptography and quantum computing. Two areas of intensiveness research. Lloyd was investigating entanglement for illumination. Entangled photos could improve photography where a flash is used by reducing the amount of noise in the returning signal.

The area that this research might benifit from are radar, x-ray, optical telecommunications and microscopy increase there sensitivity maybe millions of times.
