    While the world is struggling to make Internet more secure and maintain privacy of users, a theory given by Einstein may prove useful, as per a latest research paper. In a recently published paper, professors from Swinburne University of Technology and Peking University, have given a theoretical proof based on Einstein’s spooky theory which may give an ultra-secure internet in future.

    In 1935, Einstein and fellow researchers came up with a theory in quantum mechanics, showing how two entangled particles stay connected irrespective of their physical distance. However the real application of this theory is "sending messages" a technology that came into existence much later in 1990. A message can be sent by encrypting and using a shared key given by Einstein’s strange entanglement to decode message from sender and receiver. Using this technique, messages can be sent without any interception in transmission.

    The recent paper gives the proof that such messages can be shared between more than two people and would also provide unprecedented security for future quantum internet. Just as the way described above, sending entanglement to large number of people indicates that the key can be shared to all recipients. According to Associate Professor Margaret Reid, the recipients could then decipher the message, making it more secure. The message can be sent by up to three to four people - opening doors for transfer from many to many. Einstein’s spooky theory also enables the message to remain safe even if the device receiving it is tampered with.

    If implementation worked correctly, wouldn't it be amazing to see how Einstein's theory shows way to solve modern world's major problems.

    Thanks, Ankita.. That was way above my head! So, for lesser mortals like myself, here's an article that describes this entanglement: http://www.popsci.com/scitech/article/2009-06/quantum-entaglement

    I wonder why people are talking about this only for computers. Don't know if I am on the right dream-track here, but I can see device control being as simple as tweaking a device nearby us - and planets away a similar device behaving in the exact same manner... Maybe we are all being tweaked every day by some other earth-Godly-beings? :)

    @feltra The folks over at PopSci are really great at explaining stuff in a simple format. It was strange to note that the article was from 2009. Thanks for the share!
