Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

Random numbers are central to cryptography and various other tasks. The intrinsic
probabilistic nature of quantum mechanics has allowed us to construct a large number of …

To achieve unconditional security through quantum key distribution (QKD), users involved in
key distribution first need to authenticate each other. Classical identity authentication …

The processing of information and computation is undergoing a paradigmatic shift since the
realization of the enormous potential of quantum features to perform these tasks. Coupled …

Controlled quantum teleportation involves a third party as a controller for the teleportation of
state. Here, we present the novel protocols for controlling teleportation of the arbitrary two …

Semi-quantum protocols that allow some of the users to remain classical are proposed for a
large class of problems associated with secure communication and secure multiparty …

Quantum machine learning is at the intersection of two of the most sought after research
areas—quantum computing and classical machine learning. Quantum machine learning …

Secure communication has achieved a new dimension with the advent of the schemes of
quantum key distribution (QKD) as in contrast with classical cryptography, quantum …

Two protocols of quantum key agreement (QKA) that solely use Bell state and Bell
measurement are proposed. The first protocol of QKA proposed here is designed for two …
