More than two systems now shown to entangle:-"The EPR paradox pointed out that two well-separated systems can have a strange type of quantum connection, so that what happens in one system seems to immediately affect the other.-"This connection has recently been called 'EPR steering entanglement'.-"EPR steering is the nonlocality - what Albert Einstein called 'spooky actions at a distance' - associated with the EPR paradox and has traditionally been investigated between only two parties.-"An experiment performed by researchers from the Australian National University (ANU) and Tianjin University supports the predictions of theoretical work developed by researchers at Swinburne and Peking University.-"We used an optical network to experimentally confirm how this spooky type of entanglement can be shared over not just two, but three or more distinct optical systems," Dr Seiji Armstrong, from the Quantum Computing Centre Node at ANU, said."-
