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, based on a gaggle of researchers. If their proposal could be realised, it has the potential to disclose new details about the basically quantum nature of the vacuum.

In response to quantum physics, what we contemplate empty house shouldn’t be truly empty. As a substitute, practically imperceptible glints of quantum fields are all the time current. Over a big quantity, these fluctuations of quantum fields cancel one another out to…
