The molecules are broken down, read, and stored in a pattern buffer, and reassembled on the other side. However, there is a lot of evidence on the show to support the notion that it is not necessarily the SAME particles that make it to the other side. The being that is produced is exactly the same in every way, and even has the same memories, but it is a new person. Does the person know this, unless told? No. The last memories that the original person stored are transferred into the new person, and the new person is never the wiser.
Do you really think that it takes something like a teleporter for a reality like that to be the truth? I mean, you are never the same particles you were a moment ago, at least part of you is different. When it comes to who you were years ago, none of you is the same. I've always liked it when shows posed this question implicitly using some mechanic like this. I've seen others where people can just be copied like faxes, transported in a similar way, etc. The idea might seem scary at first, but you begin to realize how illusory that the idea of "you" actually is. When you get right down to it, there isn't a place in the brain that singularly contains your consciousness. The parts of you that sense and feels things unconsciously are equally you as well. The more we study the brain and consciousness/awareness, the more it becomes apparent that we have even less control over ourselves than we realize or like to admit.
If we could apply the same principal used to teleport someone from one place in spacetime to another to in fact create duplicates of people (clones aren't really the right word in this case), are they all really the same person? Obviously that answer is no, a single person can no longer be "single" if multiple versions of that person exists in front of you. We would tend to think they are all different people who happen to be that same person. I mean, at the exact instant of their creation (or rather duplication), they all the materials that made them up matched completely. The longer time passes, the more divergent these people become from that person they all started from, so technically they really are different people. However, which person is the original? I mean, do we have to "tag" each individual particle that makes up a person and compare it at a later time and see if the particles making them up are still "tagged" in order for it to be that person still? If the duplicates were actually made from teleporting someone's information and the duplicates were actually made at the same time, can we say an original exists? Can we say an original actually existed? Well, we did see one person before three came out, right? I guess they are the original.
Now onto what these duplicates feel about themselves. They all claim to be the same person, although each of them is clearly separate and they can confirm that their consciousnesses aren't actually existing in three places at once. Their mind is telling them that they are indeed that person, and none of them would actually be wrong. They are in fact that person, if we go by a DNA basis alone, or if we go with many of our multiple definitions of what it means to be "you". The only conclusion one can come to is that our current concepts of what "we" are as "individuals" is inaccurate, if not completely wrong. Our ideas of what make us "us" are useful for most practical applications, much in the same way that it is useful to introduce young people without a background in physics to Newtonian physics before jumping straight into Einstein's theories of special and general relativity, or even worse, quantum mechanics. We have to backtrack and start over again (at least, mostly start over) when it comes to our concepts on what makes you an individual.
It is actually fair to say, based on this understanding, that the you at any given moment is always unique, and what determines this "you" is what you are composed of, where you are, when you are, and possibly other factors yet to be determined. If three of you suddenly existed at once, but were in different physical locations all in what we can call "relatively" the same time (considering all time scales are local, the time passing for your head and feet, or any other comparison you can make, for that matter, passes at different rates), they can still all be separately identified and exist separately... lol, obviously. Anyway, if the you that you are now is always unique from the you that existed even fractions of seconds ago, you are never the same person you think you are to begin with. As a matter of fact, given that the particles that happen to make you up exist in different local times (even if only infinitesimally different), is it fair to say a "you", in the form of consciousness, exists at all? I mentioned in another post that the brain is also capable of (and does) rewrite memories so that events that might have happened technically within 0.08ms of each other actually appear to happen simultaneously. In every way, the description that consciousness is a linear representation of non-linear systems is correct. TV stations don't have to worry about the audio and visuals syncing up as long as the audio happens within 0.08ms of the visuals, your brain will take care of the rest. They don't happen at the same time (are non-linear), but are represented linearly. Our idea of us is a useful concept to explain, simply, what happens in our world. Why you decided to do something, how something happened to you, what happened to someone else, etc. It isn't accurate beyond those simplified representations.
But clearly, you experience that you exist. You experience dreams too though, right? They exist in a way, but perhaps not in a way that isn't disturbing to us when you get down to it. You exist in the same way your dreams exist. To everyone but you, your experiences and dreams are merely a result of physical phenomena. If we go ahead and entertain the idea that we are somehow more than the manifestation of these physical phenomena, maybe this is actually comforting, I don't know. All I do know is that believing you are the same you from moment to moment is erroneous. Useful, but simply not possible. And when you really think about it, it makes a lot of sense. Are you actually the same you that you were as a child? Not at all, even if you once were, you aren't now. Why is it any different from a few seconds ago or a day ago? Just like Kirk being killed when beamed in Star Trek and him being none-the-wiser that he is no longer that person, nor is anybody ever the same person they were before (and neither are they typically aware of it).
