Hello,
Below is a link to and some excerpts from a an interview with an Austrian physicist Anton Zeilinger who talks about teleportation, the information stored in a human being and freedom in physics.

Some excerpts:
"But I believe that quantum physics tells us something very profound about the world. And that is that the world is not the way it is independently of us. That the characteristics of the world are to a certain extent dependent on us."
"With the choice of the measuring equipment we've had a major impact on reality. But the answer that nature gives is completely random.
(INTERVIEWER): I choose the measuring equipment, and nature chooses the result?
That's right. I call that the two freedoms: first the freedom of the experimenter in choosing the measuring equipment - that depends on my freedom of will; and then the freedom of nature in giving me the answer it pleases. The one freedom conditions the other, so to speak. This is a very fine property. It's too bad the philosophers don't spend more time thinking about it."
"... for me the freedom to ask questions to nature is one of the most essential achievements of natural science. It's a discovery of the Renaissance. For the philosophers and theologians of the time, it must have seemed incredibly presumptuousness that people suddenly started carrying out experiments and asking questions of nature and deducing laws of nature, which are in fact the business of God. For me every experiment stands or falls with the fact that I'm free to ask the questions and carry out the measurements I want. If that were all determined, then the laws of nature would only appear to be laws, and the entire natural sciences would collapse."
"Yes. For me the concept of "information" is at the basis of everything we call "nature". The moon, the chair, the equation of states, anything and everything, because we can't talk about anything without de facto speaking about the information we have of these things. In this sense the information is the basic building block of our world."
"We've learnt in the natural sciences that the key to understanding can often be found if we lift certain dividing lines in our minds. Newton showed that the apple falls to the ground according to the same laws that govern the Moon's orbit of the Earth. And with this he made the old differentiation between earthly and heavenly phenomena obsolete. Darwin showed that there is no dividing line between man and animal. And Einstein lifted the line dividing space and time. But in our heads, we still draw a dividing line between "reality" and "knowledge about reality", in other words between reality and information. And you cannot draw this line. There is no recipe, no process for distinguishing between reality and information. All this thinking and talking about reality is about information, which is why one should not make a distinction in the formulation of laws of nature. Quantum theory, correctly interpreted, is information theory. "
"We've now been working on the unification of gravitation and quantum physics for almost eighty years – there must be something wrong with our concepts. I'm convinced we can only succeed with an entirely new philosophical approach."
