Please let me know do you have the solution for the problem of your book "Quantum information and quantum computation"? In case you have I would very appreciate if you possibly let me know how can I get it. Sincerely your, Fasihi Dear Prof.Nielsen,

Thanks a lot for your beutiful book.
Please let me know do you have the solution for the problem of your book “Quantum information and quantum computation”?
In case you have I would very appreciate if you possibly let me know how can I get it.

Sincerely your,

Thay said in 2008 that there exist more than 12 ways to use qubits in quantum computing. http://mags.acm.org/communications/200807/?pg=14 But just recenty they announced the first "universal" quantum processor that is cabable to perform whatever computing operation. Before that it was possible to operate only with some algorithms by using qubits. http://physicsworld.com/cws/article/news/40949 May I ask how do you prefer the QM interpretation, Copenhagen or Everett?

So all I have to do in order to make one, is to work out exactly how improbable it is, feed that figure into the finite improbability generator, give it a fresh cup of really hot tea ... and turn it on!He did this, and was rather startled to discover that he had managed to create the long sought after golden Infinite Improbability generater out of thin air.It startled him even more when just after he was awarded the Galactic Institute's Prize for Extreme Cleverness he got lynced by a rampaging mob of respectable physicists who had finally realized that the one thing they really couldn't stand was a smartass."

Although I have an engineering background I can't easily manage the mathematicae behind QC and it seems to me that there might be huge opportunities applying QC to business information systems. I am a business consultant and usually deal with dataming problems and stochastic rules for managing complex business processes. Any advance on these fields based on QC? I can roughly imagine "unimaginable" possibilities: management of huge amounts of unstructured data, simulation of thousands of business scenarios with just a mouse-click... Further explanations, blogs or papers with regard to these issues would be very welcome. Thanks in advance! Thanks for these “simple” explanations.

If it is proven, which scientific method is used (mathematical, physical or their combination) ? With highest respect, Alexander Dear Mr. Nielsen,

Is the statement ‘Quantum information theory is generalisation of classical Information theory’ scientific fact or just something what is believed in and needs a proof ? If it is proven, which scientific method is used (mathematical, physical or their combination) ?

With highest respect,
Alexander
