Six degrees of separation or more, everyone is entangled with everyone else. So is everything in the universe. Dig a small hole in a ground, and you’ll find an entangled mass of roots—entire ecosystems of insects, fungi, bacteria essential to the survival of not just the plants, but also ourselves. Dig deeper, and you’ll find that every electron is connected to every other electron, each quark to all quarks. Think big, and you’ll learn that all matter is gravitationally attached to all other matter—so that when you slam your car into a wall, you’re really smacking into the combined inertial mass of all the stars in the sky. Of course, personal entanglements are often the most interesting, and artists entangle both their audiences and their protagonists in a variety of delicious ways.
For our October 19th Categorically Not! we’re delighted to have John Preskill, physicist and Director of Caltech’s Institute for Quantum Information, who will explain why he loves quantum entanglement—that elusive property that makes information stored at the atomic distance scale fundamentally different from information in the macroscopic world. By exploiting quantum entanglement, a quantum computer should be able to solve problems that are beyond the reach of any conceivable digital computer. Preskill is less weird than a quantum computer, and easier to understand.
At sunset, we’ll join Brenda Hutchinson ringing bells along with people all over
the world as part of her latest interactive performance. (See dailybell2008.blogspot.com.)
