Albert Einstein's 'spooky' theory, a skepticism about quantum mechanics, may lead to ultra-secure internet, so the researchers in Swinburne University of Technology in Australia and Peking University in China believe. In 1935, Einstein highlighted his reservations about quantum mechanics in a phenomenon known as 'spooky' action at a distance, which is the strange way in which entangled particles stay connected even when separated by huge distances.
Associate Professor Margaret Reid from Swinburne's Centre for Quantum and Optical Science stated that so far the real application for this theory has been for "messages being shared between two people securely without interception, regardless of the spatial separation between them." In their paper, they've submitted theoretical proof that such messages could be shared between 2 or more people and may offer unprecedented security for a future quantum Internet.
Scientists realized in the 1990s that a message could be transmitted securely via encrypting and using a shared key generated by Einstein's strange entanglement to decode the message from the sender and receiver. Using the quantum key ensured the security of the message from interception during transmission. Making Einstein's entanglement available to a larger number of people implies that the key could be distributed among all the concerned receiving parties, so they have to team up in order to decipher the message, thus making the message more secure. Also, the messages shall remain secure even if the devices receiving the message get hacked or tampered with, due to the spooky nature of Einstein's entanglement.
Reid stated that implementing this to a situation involving several people may pave way towards the development of a more secure internet – with lesser messages being intercepted by third parties.
