relies on individual photons to carry quantum information, but even the best optical fibers today can only carry these photons a few hundred kilometers before light dissipation makes the process impossible.
Section 2 introduces some related works about quantum cryptography
. Section 3 presents preliminaries of quantum physics and quantum communication.
Then, Section VI addresses quantum cryptography
, which is the first application to an implementable communication system.
said it has signed a memorandum of understanding with SK Telecom to collaborate in the development of quantum cryptography
The first quantum cryptography
issue was presented by Bennett and Brassard in 1984 .
It seems likely that quantum cryptography
(QK) or to be precise, quantum key distribution (QKD), can be used in every day's life to provide unconditionally secure distribution of secret key material.
While today's encryption systems are considered reasonably secure, the possibilities of quantum cryptography
and quantum computing offer a whole new dimension and threat to computerized secrecy.
You may have heard of quantum computers and perhaps even quantum cryptography
, a form of secure communication that basically defeats potential eavesdroppers by relying on the fact it is impossible to observe a quantum system without disturbing it too.

is an emerging technology based on quantum mechanics and the phenomena and the properties of light.
His topics are basic ideas of classical and quantum computational models and complexity classes, mathematical tools and simple quantum mechanics required for quantum computing, quantum gates and quantum circuits, quantum algorithms, quantum error correction, quantum teleportation and superdense coding, and quantum cryptography
5 ( ANI ): A team of British scientists have reportedly discovered a way to build communications networks using quantum cryptography
and impenetrable codes, crucial for sensitive electronic data transfer.
