Re: implications of the brain as a quantum computer?

I still don't even know what all of it means, really. I'm trying to read up on a ton of literature out there but I'm not sure if what I'm interpreting/deciphering from these Quantum Mind theories is going to gel with my story or not.

So I came here. I've been here in the past and you all rock.
A quantum computer in theory works simulataneously with other quantum computers in parallel universes.

This is supposed to work via quantum interference whereby all the quantum computers share the workload of the program and pass qubits of information to each other, The result is then shared out simultaneously to all the other quantum computers.

This results in as you can imagine a very fast super computer.

Even a small QC running with only a few qubits of processing power would be able to do computations that standard supercomputers can only dream about doing.

David Bohms idea about the brain being a quantum computer along with Roger Penrose and many others is interesting and allows for the processing power needed to create conscious thought.

No one knows where concious thought comes from and is somewhat of a mystery, the brain has been electronically mapped for some time now and we are no nearer to understanding how it produces concious thought.

Arguments against the brain as a quantum computer run as follows

How does the brain produce quantum interference ?
Which area of the brain is responsible for producing quantum interference.

The above is a pretty simplistic synopsis on quantum computers its actually a lot more complicated but none of this really ties into your story on pneuspeed

Hope this helps.

Peace

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
