Every traveler is always dreaming about ways to
make their journey pass quicker. I also realized this after 19 hours journey to
France. No one would feel any discomfort if journey lasts only 0 seconds. Very
quick isn't it? It's even faster than light if you are traveling over a huge
distance, for example going to the Mars. But what device could actually do it?
These things are usually met in almost every science fiction movie- they are
called teleportation machines. People have fantasized about traveling quick and
far from very early days. The first written story appeared as early as 1877 in
Edward Page Mitchell's story "The Man Without a Body". After it everyone
put only more and more effort to create a real teleportation machine. But did
they succeed? Apparently they did! Scientists were studying real teleportation
since 1997. Sadly it is really different from teleportation we imagine. It will
take decades to transfer the smallest lead ball you could ever imagine as this
effect was achieved only for photons. Despite this, scientists are moving
forward and teleportation record was broken by Chinese researchers. Instead of
16 km they managed to transfer photons by almost 100 km, which is 6 times more
than anyone did it before. So how was this made? Firstly teleportation can
appear only between entangled photons which means they have to interact to each
other to get the same quantum state and then after separation if one photon
changes another becomes the same as well. This leads to the idea of having our
avatars in every place of the world in order to be able to teleport, but agree
with me, it is better than nothing. I can already imagine transatlantic
airplanes (maybe even galactic starships) full of humanoids. We would transfer
our minds to them only after the flight. Just imagine comfort of this! I can
already see increasing tourism as you can have a truck full of them and no one
will complain about it. But let's go back to the topic. The biggest problem
till now was laser pulse dispersion, which caused a reduced number of photons
reaching the target. It was solved by using very fancy optics with which even
this camera couldn't compare http://easyphys.blogspot.co.uk/2012/04/digitalizing-universe.html.
This is one of the most welcome devices so let's be patient.
