You are not helping me Saibal! I was just recovering from a terrible new quant-phys crisis! (My last crisis get me stuck in papers by Yu Shi on the quantum halting problem, quite difficult). I mean I have just read about a hundred quantum computing or quantum information paper. I have so much comment that I will perhaps send a quant-phys paper myself (and then gives the reference to the lists for those who want discussed it). There has been a lot of formidable discoveries showing QM is much more weird that simple entanglement could have let us believe, like new form of non locality without entanglement to name just one. Have you seen the paper by Freedman? I begin to realise that all TOE are equivalent to Universal Quantum Machine, and that the mind-body problem is equivalent to explaining a natural connection between Classical Universal Machine and Quantum Universal Machine. Teleportation and other "classical" part of a quantum computer like those described by operators in Clifford Algebra are more and more important imo (Gordon is right!).
Just to name a beautiful paper any many-worlder should read and meditate: "Quantum mechanical histories and the Berry phase", by Anastopoulos and Savvidou. That berry phase is an intriguing fundamental and general feature of the quantum. It makes me believe (through universal topological quantum computing, cf Freedman) that a lot of new form of general fault-tolerant (robust) quantum machine are possible ... The bad news is that we will be obliged to revised our (non commutative) geometry! :-) Bruno PS For those who does not know the quant-phys archive, to find those papers, search with the name (like Freedman, Anastopoulos, ...) on the quant-phys archive: http://xxx.lanl.gov/find/quant-ph or with subject like "berry", "teleportation". --- original message --- >High Energy Physics - Theory, abstract >hep-th/0201092 >From: Stephen Blaha <[EMAIL PROTECTED]> >Date: Mon, 14 Jan 2002 21:57:12 GMT (634kb) > >A Quantum Computer Foundation for the Standard Model and SuperString Theories >Authors: Stephen Blaha >Comments: 78 pages, PDF > > > We show the Standard Model and SuperString Theories can be naturally >based on a Quantum Computer foundation.
