Laws of physics do not prevent the teleportation of large objects, including humans, professor says
[...] ’’If you believe we are nothing more than a collection of atoms strung together in a particular way, then in principle it should be possible to teleport ourselves from one place to another.
’’In practice it’s extremely unlikely, but to say it can never work is very dangerous.
’’I would not rule it out because there’s no fundamental law of physics preventing it.
’’If it ever does happen it will be far in the future.’’
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.
