An international team of researchers has achieved an important theoretical result by finding that quantum teleportation – the process of transporting quantum information at the speed of light, which could in theory be used to teleport macroscopic objects and, one day, even humans – can be achieved in a much more energy-efficient way than was previously thought.
How teleportation works
For the best part of the twentieth century, teleportation was dismissed as purely as a science fiction pipe dream. The problem lay in the approach: the only possible way to achieve it, scientists thought, would be to measure the position and momentum of every single atom of the object to be teleported, send it to its destination using classical (non-quantum) information, and finally rebuild it based on the set of “instructions” received. But science says that the first step – the perfect measurement of a particle – is simply impossible due to Heisenberg’s uncertainty principle.
