In the little sci-fi story, I saw nothing that required quantum properties in the computers. I don't think we can even predict what QCs will ultimately do to change our lives.


That's an important point it's hard to say how quantum computers will affect our lives. There was another article recently we read where computer modeling is reaching the same or similar outcomes as actual testing. When computer models reach the complexity where physical testing is no longer necessary and the eventual outcome can be determined through the use of an extremely elaborate model. These models should be able to be run on quantum computers giving us a fantastic jump over existing computational capabilities and a clear view of are environment and existence. One could envision a extremely elaborate whether model telling us the weather for an extended period of time with absolute accuracy. The advances in aerospace through modeling of new airframes and perhaps even new shuttle designs should be substantially enhanced with the modeling through quantum computers. There are likely dozens of examples that could be given in real-world situations where computer models drawn would provide a wealth of information about a given problem.

We could perhaps see a situation where our entire life is modeled to a detail that is unprecedented. We could simply input all known information about everything and begin to predict how specific events would transpire based on some catalyst. Good examples would be if a meteor were to strike the planet how would one expect individuals on the opposite side of the planet to react and how one would advise in preparation for such an event. Another good example would be to simply input everything known and present a catalyst in the form of a new virus then begin to predict the spread of the virus and its related problems. One could then extract from this scenario the most likely vaccines that will be required to be on hand and the quantity necessary to prevent widespread infection. Again there are likely many many possible scenarios for modeling that are currently impossible with technology simply because we do not have and cannot express the complexity of the problem with in the code and cannot possibly hold for a clear answer to the question without in some cases hundreds of years of the fastest supercomputers on the planet performing the search for the answer. But in the use of significantly advanced quantum computers these answers should be child's play in the performance of its duties for this computer.

In the above examples I do not believe that we actually require a artificial intelligent computer as previously discussed we simply require a elaborate model to perform any of the requested operations.

Does anyone hear know as I have a question on the number of quid bits currently being discussed for an initial quantum computer development. Are we discussing the likelihood of constructing a 100 quid bits computer or are we expecting the number to be closer to 20 or 30. My next question would be is there some avenue that would support the manufacture of 1000 or 10,000 quid bits and to what the eventual upper limits are.



How many qubits could we actually use? I understand that 300 would have more states than the atoms in the known universe. Most modelling applications will probably require significantly less.

I also understand that scientists have as of this year, benchmarked quantum control of a 12 qubit system

I don't believe weather prediction, due to the Butterfly Effect.


In the 1950s they thought that in year 2000 the world would look like what we now think 2060 will look like. The problem is predicting the future on paper is much easier than actually making it happen.
