Have We Made The Breakthrough To The Future
The vision and the plot of quantum entaglement around which the
stand out movie Star Trek was created may just be coming out into a reality. This record has now been set. The feat was
achieved by a team of Chinese scientists who sent a packet of information
from Tibet to a satellite in orbit, up to eight hundred and seventy miles
somewhere around to one thousand and four hundred kilometres above the Earth's
surface. Yes the farthest quantum teleportation record has now been
set.
The Fundamental Phenomenon Of Spooky pairs
This experiment took
advantage of one of the several phenomenons that describe quantum mechanics. This
concept is given the terminology entanglement or "spooky action at a
distance" as Albert Einstein called it. As interesting the name sounds I
could not help but do some preliminary secondary research around the
terminology. So what exactly happens is that two particles are entangled a state of entangled photons, they
remain in this connected state so that an action performed on one affects the
other as well, no matter how far apart the two are. In the same vein, when one
measures the state of one particle in the entangled duo, you'd automatically
know the state of the second. Physicists call the states
"correlated," because if one particle — a photon, for example — is in
an "up" state, its entangled partner will be in a "down"
state — a kind of mirror image. (Strictly speaking, there are four possible
combinations for the two particles to be in).
The weird part is that once the state of the first particle is measured,
the second one somehow "knows" what state it should be in. The
information seems to travel instantaneously, without a speed-of-light limit.
The common man thinks of teleportation as if it is all about moving an actual object or a photon form one place to another. This mindset of People having this 'Star Trek' approach is the difficult one to make them understand. They think of atoms being teleport. However in actuality what is being moved is information from one quantum bit to another quantum bit. There is no matter but only information. That's hard to get your head around. The wider picture is that though experiments like this have been done in the past, but Howard Wiseman, director of the Center for Quantum Dynamics at Griffith University in Brisbane, Australia, was recorded having had told the Live Science in an Email that this one expands the possibilities for the technology. A futuristic technology 'Star Trek' fans would love to see perhaps as a modern science fiction coming into reality. A futuristic concept of quantum communication is almost a reality now.
