Apart from a few promising prototypes, quantum computers don't really exist yet, but never mind that--the very thought of them is enough to give a geek goosebumps. Imagine it: a computer capable of processing data not just on your desktop but in a million parallel universes all at once. The concept sounds like science fiction, but the freaky laws of quantum physics make it a concrete possibility. And the implications--as science journalist Julian Brown makes plain in Minds, Machines and the Multiverse: The Quest for the Quantum Computer, a daunting yet consistently gripping look at quantum computation's high frontiers--are sweeping.

Computers powered by quantum weirdness, Brown tells us, could outperform existing machines to astronomical degrees, solving in minutes problems classical computers might take millennia to work through. But more to the point, the theoretical research that is making quantum computers plausible--led by gifted physicists like Rolf Landauer, David Deutsch and the late Richard Feynman--has already opened up intriguing new ways of thinking about the world and about computation's place in it.

But Brown shows equal commitment to explaining not only what makes quantum computers fascinating but what makes them work. This is not, in other words, a book for those who blanch at the sight of complex equations and circuit diagrams. Still, Brown's explanations, while dense with information, are unerringly lucid, and anyone who sticks with them to the end will come away with exactly what this book promises: a penetrating understanding of a mind-bending technology. --Julian Dibbell, amazon.com -- Dieser Text bezieht sich auf eine vergriffene oder nicht verf�gbare Ausgabe dieses Titels.

Just how smart can computers get? Science journalist Julian Brown takes a hard look at the spooky world of quantum computation in Minds, Machines, and the Multiverse--and his report is optimistic. Based in large part on the groundbreaking work of David Deutsch, the book mostly sidesteps the shouting matches of the AI debate and instead explores the history of computation and quantum theory before turning to the exciting advances likely to come out of their merger. While some readers might cringe at the blithe dismissal of classical computing as a relic, Brown shows us why quantum computing is faster and more powerful, and is a good candidate for replacing its predecessor.

The author doesn't pull any mathematical punches, but injects enough humor and personalization into his writing to keep the book from crumbling to dust. Indeed, portraits of such luminaries as Deutsch and Feynman are more engaging than those found in some biographies and are enlightening on their own. But the real power and charm of Brown's prose lie in its straightforward explanation of the arcane details of the multiple-worlds theory, "qubits," and quantum logic in language any informed reader can understand. There are more questions than answers in Minds, Machines, and the Multiverse, but the questions are profoundly satisfying all by themselves. --Rob Lightner -- Dieser Text bezieht sich auf eine vergriffene oder nicht verf�gbare Ausgabe dieses Titels.

Einleitungssatz
Gaunt, hair unkempt, and skin a ghostly shade, David Deutsch cuts a strange figure even by the standards of the eccentrics and oddballs that so often inhabit the upper reaches of science. Lesen Sie die erste Seite

Mind-blowing! 7. Mai 2000

Von arnold trent

Format:Gebundene Ausgabe

A wonderful overview of the history and science of this extraordinary new discipline. Brown's documentary approach interlaces explanations of quantum computers with comments from the pioneers of this field including David Deutsch and Richard Feynman. It makes for riveting reading with many witty asides thrown into some far-sighted discussions of where the subject is leading. David Deutsch comes across as a true visionary even if his ideas concerning multiple universes sound far-fetched. Rather like Penrose's, "The Emperor's New Mind", Brown caters for multiple tastes by writing for a general audience but adding (mostly in appendices) some mathematical explanations and circuit diagrams. These can be can be safely skipped without losing the narrative thread. A pity to do so though because his explanations are a delight. Thoroughly recommended.

Choose your worlds carefully... 17. April 2000

Von Douglas J. Page

This is a decent sequel to David Deutsch's Fabric of Reality. Unlike much of the contemporary scene, this book doesn't dumb itself down for the lowest common denominator. The nice thing about this book though, is that while it gets down into the nitty gritty you can still follow along at whatever level you are at. Some people might give a ho-hum about quantum computers but once these people get past their own inertia they will be compelled to accept just how profoundly quantum computers will change our current collective conceptual framework. Also, at a little over half way through this book you might begin to wonder where the Mind part fits in with the Machine and Multiverse parts but by the final lines everything slips snuggly into place. Perhaps the only disappointment, which is surely not the book's fault, is that quantum computers are still only ideas not actualities. However exciting this topic may be, it is a topic about the near future, not the present, and so we are naturally left wanting more.

The Other Me's Read It and Liked It I think 8. April 2000

Von Ein Kunde

it seems that in one of the multiverses that surround me like a fog these days, another 'Me' has already read this book. What seems to bug this other 'Me' about the book, is the tacit assumption that such superpositions are *never* experienced in the 'classical' world. Well, jeez, what else is schizophrenia all about, eh? And if you read some of the old Zen Master anecdotes, they are clearly talking about living in a world of superposition, where 'to go one mile east, is to go one mile west'. What we need is for Thomas Cleary to have a go at doing a syncretic synthesis of Zen and Physics. It's about time for a newer 'Tao of Physics' it seems to me!
