The nature of quantum mechanics provides us with an opportunity to statistically detect
eavesdropping in quantum key distribution (QKD) protocols, which is unimaginable in …

Quantum cryptography provides perfect secrecy if the key exchanged is used for one-time-
pad encryption. However, this requires very long keys which are not practical in most …

In this paper, a quantum version of Diffie-Hellman key agreement protocol is developed
using the commutative rotation transformations. Qubits rotated by secret rotation angles and …

This paper discusses correcting small rotation errors in the three-stage quantum key
distribution (QKD) protocol using only two logical qubits thereby increasing communication …

Quantum key distribution (QKD) protocols form a natural choice for encryption in optical
networks. All the QKD protocols use errors caused due to random measurements by Eve to …

We present a quantum public key cryptographic protocol that allow Bob to send any arbitrary
qubit state to Alice, securely. The proposed protocol (quantum pad-lock protocol) uses …

This paper looks at using quantum teleportation for secure message exchange. Although the
proposed protocol has parallels with Ekert's protocol for key distribution, we look at the issue …

For students and researchers alike, the field of quantum computing is difficult to approach.
The nature of quantum computing runs counter to the intuitive framework applied to most …
