Quantum entanglement, once described by Albert Einstein as
"spooky action at a distance", has long fascinated the public and puzzled scientists.
For quantum practitioners, entanglement is a connection between particles that is a key feature of quantum computers, enabling them to simulate natural quantum systems like molecules, pharmaceuticals, or catalysts.
In a new study published in Science, researchers have demonstrated quantum entanglement between two atomic nuclei separated by about 20 nanometres.
