We may be able to harvest the quantum property of entanglement from apparently empty space, according to a group of researchers. If their proposal can be realised, it has the potential to reveal new information about the fundamentally quantum nature of the vacuum.
According to quantum physics, what we consider empty space is not actually empty. Instead, nearly imperceptible flickers of quantum fields are always present. Over a large volume, these fluctuations of quantum fields cancel each other out to…
