Einstein-Podolsky-Rosen Paradox and Certain Aspects of Quantum Cryptology with Some Applications

The potential power of quantum approach to computing would render the classical cryptology almost superfluous in the not too far away future. The main problem of cryptography is that of key distribution (hereafter KD). KD can be broadly classified into public KD and private KD. In conventional classical cryptography it is the private KD of RSA type algorithms that assumes the computational complexity of factorization. Quantum computing and computational algorithms would make things possible compared to that which cannot be even imagined by conventional means. For instance, Shor quantum algorithm, defined in Shor (1997), would make an unparalleled and unheard of quantum leap as far as factoring is concerned. As an illustration, if one wants to factor a very large integer (say, having 250 digits) what the existing very fast super computers might take is a time of the order of the age of the Universe ABSTRACT
