well, if you want the whole scientific thing.. here it is
Yes, it is possible, scientists in 2010 manage to teleport some atoms across a gap of 5 metres. However, these were incredibly small and required vast amounts of energy. It has not been tested on any molecule or larger items however to teleport would require a large number of strongly charged electrons. Though it has been possible, it will still be quite a while before larger particles can be successfully ported.
The biggest problem with teleportation is that it basically destroys the charge between the molecules so they "disintergrate" or "vapourize", this is the easy part, its putting these charges back together that is the problem. Breaking it down is like destroying a large puzzle, it needs to be pieced back together after moving it.
The problem with this is that it could work with metals and natural elements due to the atomic structure, however, biological matter such as people are alot more complicated.
Chances are, if teleports are created for human usage soon, it could cause mutations as the cells have to be rematerialised after being broken down. This could form cancerous cells.
Instant teleportation is debatable, if a structure is very complex, then it may take a long time to materialise... if the thing is living, it will probably die since the cell configuration can be mixed up. You never know what could happen though...
There is no date on when teleports will be availiable, but it could be in a couple of dozen years (or longer/ shorter since no one knows top secret government research). When it will be availiable, it will be exceedingly expensive and dangerous.
