Entangled particles acquire a merged identity

This is information we in the Energy Medicine/Informational Medicine community know to be so, it plays a big part in the way our products and services work. However it is good to see that science is starting to catch up with their understanding!

Prof Hanson, from Delft University of Technology in the Netherlands:

Prof Hanson’s team showed for the first time that it was possible to teleport information encoded into sub-atomic particles between two points three metres apart with 100% reliability.

The demonstration was an important first step towards developing an internet-like network between ultra-fast quantum computers whose processing power dwarfs that of today’s supercomputers.

Teleportation exploits the weird way ”entangled” particles acquire a merged identity, with the state of one instantly influencing the other no matter how far apart they are.

Giving one particle an ”up” spin, for instance, might always mean its entangled partner has a ”down” spin – theoretically even if both particles are on different sides of the universe.

Albert Einstein dismissed entanglement, calling it ”spooky action at a distance”, but scientists have repeatedly demonstrated that it is a real phenomenon.

In Prof Hanson’s experiment, three entangled particles – a nitrogen atom locked in a diamond crystal and two electrons – were used to transfer spin information a distance of three metres.

Four possible states were transmitted, each corresponding to a ”qubit”, the quantum equivalent of a digital ”bit”.

Each ”bit” of information in a classical computer represents one of two values, normally zero or one.

But a ”qubit” can represent a zero, a one, or a ”superposition” of both states at the same time.

The research is published in the latest online edition of the journal Science.

Prof Hanson said: ”The main application of quantum teleportation is a quantum version of the internet, extending a global network that we can use to send quantum information.

”We have shown that it’s possible to do this, and it works every time that you try.

”It provides the first building block of the future quantum internet.

”One application nearest to a real life application is secure communication.

”What you’re doing is using entanglement as your communication channel.

”The information is teleported to the other side, and there’s no way anyone can intercept that information.

”In principle it’s 100 per cent secure.”

A more ambitious experiment, involving the teleportation of information between buildings on the university campus 1,300 metres apart, is planned in July.

It is hoped this will answer Einstein’s main objection to teleportation, the possibility that a signal passes between entangled particles at the speed of light.

”I believe it will work,” said Prof Hanson.
