'Quantum entanglement is so bizarre that Albert Einstein refused to accept it as true for many years.'
'The discoveries made over the last century by physicists studying quantum mechanics—some of which suggest that reality is only made certain by the presence of a conscious observer—is nothing short of mind-blowing. One particular concept, entanglement, was so out there that Albert Einstein called it “spooky action at a distance” and for many years refused to accept it as true.
But now, a new experiment has scientists believing that quantum entanglement doesn’t just apply to spatial gaps, but time itself.
Einstein famously battled with physicist Niel Bohr over the predictions and theories of quantum mechanics, such as the wave function. He also corresponded with Erwin Schrödinger—yes, of Schrödinger’s cat—and in one of his 1935 letters, Einstein stated: “I know of course how the hocus pocus works mathematically. But I do not like such a theory.”
The principle of entanglement held that it was impossible to independently describe two quantum systems that had once been united. One influenced the other instantaneously across vast distances, which meant that in some cases it appeared as though information was being transmitted and received faster than the speed of light, which Einstein believed was impossible.
Critically, these two quantum systems co-existed at the same time. But is it possible that “spooky action” can take place between systems from different time periods?
This is the shocking suggestion by a team of physicists at the Hebrew University of Jerusalem, who believe they have used “entanglement swapping” techniques to show that quantum nonlocality also includes temporal nonlocality. '
