With the advent of a single Phosphorus atom CPU using quantum mechanics, and the possibility of opening up a worm hole big enough for a calculated kind of contact with this CPU, is it possible to take data from a transmitter located in the future? Even just a few minutes into it?

I consider that the computer, at first, and experimental one, could store the information, before human contact, in a file with a time on it. And would need be high fidelity and secure. Opened after the point in time came, it drew from. A person would need the same qualities in order to prevent a time warp or  need faith and patience.

Data by itself may not cause a time warp. But other qualities in a person would need be constructive, benevolent and devoid of accusations. Proper for and against.

In a chain of events that goes through, computers or minds, it is interesting to think of it breaking in there. Breaking into a time warp.

There have been investigations into single-bit computers, in the form of cellular automata. http://en.wikipedia.org/wiki/Cellular_automaton
And ongoing work on storing quantum states in isolated atoms.
However, to do anything really interesting, you really need a network of single-bit computers, and means of doing operations across multiple qubits.

There are some fundamental reasons why some physicists would like to think that time travel is impossible (and movie-makers would like to make out that it is possible).

For now, single Phosphorus atom CPUs and worm holes are still hypothetical.
But you are right - if time travel were possible, you would want it to be in benevolent hands, rather than malicious!

I have begun reading cellular automaton. Interesting.

Yes I am interested in speculating about tiny worm holes made as big as atoms or molecules. Stephen Hawking mentioned he thought there already were many worm holes much smaller than atoms. And that in space time travels at different rates in different places.

Stephen describes the enormous amount of waste light in a time portal. He is sure they can't exist. If there was such a thing would it be local or effect all time motion?

Personally, I think we could possibly see the past and future but not effect it.

Looking at something like tomorrows stock market or weather and looking at a computer with a data time travel CPU in a firm computer, robust in design and programming and secure from data theft, could hold such information. securely until opened. It could then be checked, against the current reality.

A person holding such information before the date, apart from character but not forgetting empathy... would need a kind of committed fidelity... Faith and patience. Firmity, resolution and accuracy.

There is also the factor of, the observer simply observing changing the course of events.

With regards to character, there are betters who would like to say that if a person they knew of lacked a certain provision that they would not have say, won over the wife he now has, and could want to test it. If it is a couple now and he can see ahead how things go, he could test that. And be unkind... and there is room for this with accusations as well as bets...

Nice to think that in a situation such as with W Churchill, he could acquire knowledge of enemy maneuvers and future battle outcomes and alter them, without creating a time warp but some kind of waste data instead.
