U.S. officials and scientists yesterday unveiled a plan to construct a potentially hackproof quantum Internet to operate parallel to the world's existing networks. The Department of Energy (DoE) and its national laboratories will form the project's main support pillar, and DoE official Paul Dabbar suggested it could be funded using some of the $500 million to $700 million in annual federal quantum information technology investments. A quantum Internet relies on entangled photons to share information over long distances without physical links; the race to create one is a global competition. Researchers said attempts to observe or disrupt photons or quantum bits in a quantum Internet would automatically change their state and destroy the transmitted information. A quantum Internet also could interconnect various quantum systems and boost their computing power.  ... '
