Lasers fired at crystals could uncover quantum nature of the vacuum

We might be able to harvest the quantum property of entanglement from apparently empty house, in response to a gaggle of researchers. If their proposal will be realised, it has the potential to disclose new details about the essentially quantum nature of the vacuum.

Based on quantum physics, what we take into account empty house will not be really empty. As a substitute, almost imperceptible glints of quantum fields are at all times current. Over a big quantity, these fluctuations of quantum fields cancel one another out to…
