And on the teleportation front....

"Quantum entanglement is valuable in transmitting particles such as atoms and photons where the most delicate properties are significant and where simple approximation is not enough," he explains.

"Teleporting a person, on the other hand, would not require reproducing the quantum state anything like as exactly.

"Everything we know about biology and how molecules fit together to produce a living being, including the brain, indicates that creating some level of approximation would give you a real person who was a serviceable replica of the original in terms of looking the same and thinking the same thoughts, without necessarily being a perfect quantum replica.

"The teleported person would end up slightly different, but not in a biologically important way."

The implication of this is that you could scan a person using some advanced form of the technology used to perform MRI scans, and transmit that scanned information somewhere else -- using normal electrical or sound signals -- where it would then be reassembled into an approximation of the original.

"It's the same principle as a fax machine," says Bennett. "When you fax something what comes out the other end obviously looks like the original and contains the same information. It's not the same paper, however, or the same type of ink.

"It's the same, but not the same.

"We already have three-dimensional fax machines, so the basic theory is there."
