Quantum key distribution (QKD) is an innovative technology that exploits the laws of
quantum mechanics to generate and distribute unconditionally secure shared key for use in …

In this paper the experimental and the numerical study of an optical key distribution quantum
cryptography using BB84 protocol has been achieved. We create secret quantum key and …

Quantum Key Distribution (QKD) is one of the most important aspects of quantum
cryptography. Using laws of quantum mechanics as the basis for security, the key …

Here we analyze the security of quantum dense coding protocol in which the keys are
encoded on d-dimensional Hilbert space. The incoherent attack is considered during the …

Quantum key distribution (QKD) has evolved as a robust way of secret key distribution based
on renowned modern physics concepts. To transmit sensitive information in the government …

Carry out research on the variation rule of the average mutual information between Alice
and Eve I AE, Alice and Bob I AB and bit error rate qe (AE), qe (AB), when the eavesdropper …

The present cryptography systems security depends on the hardness of factorizing an
integer number with a large number of digits to its prime integer factors. In 1994, Peter Shor …

The BB84 QKD protocol is based on the idea that the sender and the receiver can reconcile
a certain fraction of the teleported qubits to detect eavesdropping or noise and decode the …
