Have there been any recent advancements in transporters?

I believe scientists have managed to teleport a photon

nothing larger.

*************

the problem with a "transporter" idea is the following

1) it's impossible to adequately calculate the energy state and position of every atom and every electron in your body. You're too complicated. Your body cannot be "scanned" and duplicated.

2) the transporter is actually a "duplicator". More like a fax machine. You would have to have a other machine to reassemble.

3) what do you do with the original? watch the movie "the prestige"

think about it like this. If you were to accurately calculate the energy states of a Hydrogen atom, you could do it via quantum mechanics. The math is about a paragraph long. If you apply that to a helium atom, the math is about a page long. Lithium will be several pages. Anything larger must be approximated. the math is too complicated.

now image each carbon atom in your body requiring a textbook full of calculations in order to approximate the energy state of the atom. times infinite.. you have a lot of carbon atoms...too complicated.

Yes there have been some experiments on this subject.

They have found that it is very hard to remake what was decompiled. It needed a lot of machinery, time and computer processing power

It can be done for small compounds (very tiny bits of salts) over a short distance.
