Ученые из Дании впервые телепортировали объект, состояший из тысяч миллиардов атомов. Ранее удавалось это сделать только для отдельных атомов.

That is, the second system cannot be steered into any particular state at the whim of the experimenter, but the experimenter can constrain the state into which the second system evolves to lie in any chosen set of states, with a probability distribution fixed by the entangled state. He found this conclusion sufficiently unsettling to suggest that the entanglement between two separating systems would persist only for distances small enough that the time taken by light to travel from one system to the other could be neglected, compared with the characteristic time periods associated with other changes in the composite system. He speculated that for longer distances each of the two systems might in fact be in a state associated with a certain mixture, determined by the precise form of the entangled state."
