Quantum computing marketing or true?

quantum computing propaganda?

There are a lot of publications recently, about quantum computing. Quantum computing is a catchy subject, but science is different than marketing. According to this post quantum PCs can be a reality in five years time from now.

MELBOURNE: A new type of silicon chip that works on light instead of electricity could lead to the first ultra-fast quantum computer within five years, say Brit scientists.
I was watching recently a presentation which I enjoyed very much (I hope that I can do a post specifically for that) and one of the key points was that it is very difficult to construct a general purpose quantum computer similar to the ones that we use now.
So, the question is;
is it true that we can really construct quantum computer of general purpose within a decade’s time or this is just another marketing propaganda about quantum computing industry?

Personal blog of Giulio Prisco. Mainly cosmism, transhumanism, science fiction, futurism and emerging technologies. Also IT, VR and virtual worlds, and some personal stuff.


Quantum computers are not known to be able to solve NP-complete problems in polynomial time.

… The world’s leading social portal for everyone involved in quantum information science.

…Our approach to building quantum computers has been covered in a lot of different places (see sidebar in the blog) and a Harvard Business School case study.

Our goal is to make this Community Page the best collection of shared knowledge on Quantum computing.

Fresh Science News; quantum teleportation

Posted in Physics, quantum physics theory, qunatum, Science by e1saman on September 14, 2010

This is new record for quantum teleportation;

Quantum teleportation achieved over ten miles of free space

As we’ve explained before, “quantum teleportation” is quite different from how many people imagine teleportation to work. Rather than picking one thing up and placing it somewhere else, quantum teleportation involves entangling two things, like photons or ions, so their states are dependent on one another and each can be affected by the measurement of the other’s state.
