Quantum non-locality and information security
(198K, Pdf)

ABSTRACT.  We show that quantum non-locality, as discussed here, is sufficient to achieve unconditional information security without requiring advanced quantum technology, pre-shared secret keys or private quantum/classical channels between distant systems (users). Two-fold quantum non-local correlations imply two-way secret transmission in a single round with assurance of confidentiality, integrity and authenticity. Interestingly, the proposed scheme (quantum telephone or QPhone) provides resources for indefinite future secure communication and acts as life-time pad.
