Vliegen buiten de melkweg

[Marko]

Parallelle universa bestaan alleen als abstract begrip in bepaalde theorieën of interpretaties daarvan. Het is onmogelijk er informatie of materie mee uit te wisselen, en daarom is het ook geen reële optie. Het zou heel erg fijn zijn als dit soort science fiction buiten de wetenschappelijke discussies wordt gelaten.

Met de bovenstaande uitspraak zal David Deutsch niet blij zijn:

David Deutsch heeft nogal wat bekomen:

International Award on Quantum Communication 2002

In 2002 I received the Fourth International Award on Quantum Communication for “theoretical work on Quantum Computer Science”.

This was presented at the Sixth International Conference on Quantum Communication, Measurement and Computing. A transcript of the talk Physics, Philosophy and Quantum Technology (PDF file here) that I gave at that conference has been published in Proceedings of the Sixth International Conference on Quantum Communication, Measurement and Computing, Shapiro, J.H. and Hirota, O., Eds. (Rinton Press, Princeton, NJ. 2003).

Visiting Professorship at the University of Oxford

Since 1999 I have been a non-stipendiary Visiting Professor of Physics at the University of Oxford, where I am a member of the Centre for Quantum Computation at the Clarendon Laboratory.

--------------------------------------------------------------------------------

The Paul Dirac Prize and Medal 1998

In 1998 I was awarded the Institute of Physics' Paul Dirac Prize and Medal. This is the Premier Award for theoretical physics within the gift of the Council of the Institute of Physics. It is made for “outstanding contributions to theoretical (including mathematical and computational) physics”.

The citation reads:

“For pioneering work in quantum computation leading to the concept of a quantum computer and for contributing to the understanding of how such devices might be constructed from quantum logic gates in quantum networks.”

Parallel Universes

My paper The Structure of the Multiverse (http://xxx.lanl.gov/abs/quant-ph/0104033), which appeared in roceedings of the Royal Society A458 2028 2911-23 (2002), explains how the structure of the multiverse – and in particular, the way in which some parts of it consist, to a good approximation, of parallel universes – is determined by the way in which information flows in it. But before that, you should read:

Information Flow in Entangled Quantum Systems by myself and Patrick Hayden, which appeared in Proceedings of the Royal Society A456, 1759-1774 (2000), explains how, despite conventional wisdom and a great deal of futile work by many researchers in the foundations of quantum theory, there are no non-local effects of any kind, detectable or undetectable, in quantum physics.

Quantum Theory of Probability and Decisions, which appeared in Proceedings of the Royal Society A455, 3129-3197 (1999), is about what probability really is, and how the quantum theory of a deterministic multiverse, without any probabilistic assumptions, makes probabilistic predictions.

See also the following papers by David Wallace:

Everettian Rationality: defending Deutsch's approach to probability in the Everett interpretation

Quantum Probability from Subjective Likelihood: improving on Deutsch's proof of the probability rule

And other papers on his web site.

Michael Clive Price's FAQ on the Everett Interpretation. I do not necessarily endorse everything in it, but it does indeed answer many frequently asked questions correctly and is a good non-technical introduction to what the theory is about.

+++++

Een zijdeur naar een andere wereld maken doe je niet met een chemisch element (Alchemisten...1700), of met wat elektriciteit (Watt, Faraday e.d.) of met kernen (Wheeler, Pauli, Dirac etc).

Je heb dan echt zaken nodig die quantum_mechanisch werken.

Een Maglev was ten tijde van Watt pure science fiction maar als Meneer Watt in de cockpit gaat kijken ziet hij wel ZIJN naam staan.

En ik denk zo: als je bij de zijdeur naar een andere wereld staat zie je misschien Deutsch staan...

dan denken de mensen ''Wie is die man?'

Blijkbaar is het voor veel gebruikers onmogelijk om hier wetenschappelijke en on topic berichten te plaatsen. Deze laatste zijsprong naar een interpretatie van kwantummechanica is de spreekwoordelijke druppel. Slotje dus.
