Duck and Cover, Quantum Computing and Kurzweil Interview

Duck your head!

Astronomers say it may be space junk or it could be a tiny asteroid, too small to cause damage even if it hit. It’s 33 to 50 feet wide at most.

says that on Wednesday at 7:47 a.m. EST, it will streak by, missing Earth by about 80,000 miles. In the western United States it may be bright enough to be seen with a good .

Hmm..makes a good case for the Flexible Path asteroid missions, eh?

Mystery object to whizz by Earth

From the wonderful world(s) of the multiverse and quantum entanglement:

For the first time, physicists have convincingly demonstrated that physically separated particles in solid-state devices can be quantum-mechanically entangled. The achievement is analogous to the  of light, except that it involves particles in circuitry instead of photons in optical systems. Both optical and solid-state entanglement offer potential routes to and secure communications, but solid-state versions may ultimately be easier to incorporate into electronic devices.

The experiment is reported in an upcoming issue of Physical Review Lettersand highlighted with a Viewpoint in the January 11 issue of Physics.

In optical entanglement experiments, a pair of entangled photons may be separated via a beam splitter. Despite their physical separation, the entangled photons continue to act as a single quantum object. A team of physicists from France, Germany and Spain has now performed a solid-state entanglement experiment that uses electrons in a superconductor in place of photons in an optical system.

As conventional  are cooled, the electrons they conduct entangle to form what are known as Cooper pairs. In the new experiment, Cooper pairs flow through a superconducting bridge until they reach a  that acts as the electronic equivalent of a beam splitter. Occasionally, the electrons part ways and are directed to separate — but remain entangled. Although the quantum dots are only a micron or so apart, the distance is large enough to demonstrate entanglement comparable to that seen in optical systems.

In addition to the possibility of using entangled electrons in solid-state devices for computing and secure communications, the breakthrough opens a whole new vista on the study of quantum mechanically entangled systems in solid materials.

Optical connections not needed? Solid state devices can utilize quantum configurations?

This is huge. Maybe Kurzweil can get his mechanical AI sooner than thought?

A solid case of entanglement

Speaking of Ray Kurzweil, the Guru of the Technological Singularity grants an interview with the Transhumanist ezine H+:

RAY KURZWEIL: One area I commented on was the question of a possible link between quantum computing and the brain. Do we need quantum computing to create human level AI? My conclusion is no, mainly because we don‘t see any quantum computing in the brain. Roger Penrose‘s conjecture that there was quantum computing in tubules does not seem to have been verified by any experimental evidence.

Quantum computing is a specialized form of computing where you examine in parallel every possible combination of qubits. So it‘s very good at certain kinds of problems, the classical one being cracking encryption codes by factoring large numbers. But the types of problems that would be vastly accelerated by quantum computing are not things that the human brain is very good at. When it comes to the kinds of problems I just mentioned, the human brain isn‘t even as good as classical computing. So in terms of what we can do with our brains there‘s no indication that it involves quantum computing. Do we need quantum computing for consciousness? The only justification for that conjecture from Roger Penrose and Stuart Hameroff is that consciousness is mysterious and quantum mechanics is mysterious, so there must be a link between the two.

I get very excited about discussions about the true nature of consciousness, because I‘ve been thinking about this issue for literally 50 years, going back to junior high school. And it‘s a very difficult subject. When some article purports to present the neurological basis of consciousness… I read it. And the articles usually start out, “Well, we think that consciousness is caused by…” You know, fill in the blank. And then it goes on with a big extensive examination of that phenomenon. And at the end of the article, I inevitably find myself thinking… where is the link to consciousness? Where is any justification for believing that this phenomenon should cause consciousness? Why would it cause consciousness?

Kurzweil takes his reputation as the Guru of the Singularity in stride. He feels pretty confident in its eventual arrival.

Will it? Check out this interview!

    Dang, I missed it. Possibly a commuter ship full of Zionist real estate agents? :lol:

      ROTFFLMAO! :lol: Bwahahahahahahahahahaha!!!!

  2. I really do enjoy your site. I love that you post mainstream science along with non.

    1. Thanks Deirdre, it’s all the stuff that interests me, and the list grows.

      Folks don’t know what to make of that at times and it keeps ‘em guessing!

  3. Your site was extremely interesting, especially since I was searching for thoughts on this subject last Thursday.
