Quantum physicists have figured out a way to give us a double dose, according to the journal Physical Review Letters (vol 96, 060504).
Using laser beams, scientists have created a teleportation machine that generates two near-identical copies of the original.
Why only near-identical? Because Quantum Mechanics dictates that just measuring the position of a particle disturbs it and so limits the accuracy to which it can be reliably replicated — a concept known as the uncertainty principle. This makes producing an exact clone of the beam impossible.
