We Haar uniformly generate random states of various ranks and study their performance in
an entanglement-based quantum key distribution (QKD) task. In particular, we analyze the …

The quantum dense-coding (DC) protocol, which has no security feature, deals with the
transmission of classical information encoded in a quantum state by using shared …

The telecloning protocol distributes quantum states from a single sender to multiple
receivers via a shared entangled state by exploiting the notions of teleportation and …

Device-independent quantum secure direct communication (DI-QSDC) is a promising
primitive in quantum cryptography aimed towards addressing the problems of device …

We investigate the distributed dense coding (DC) protocol, involving multiple senders and a
single or two receivers under the influence of non-Markovian noise, acting on the encoded …

The distribution of typical bipartite pure states is studied within the framework of state
transformation via local operations and classical communication (LOCC). We report the …

The behaviour of genuine EPR steering of three qubit states under various environmental
noises is investigated. In particular, we consider the two possible steering scenarios in the …

Noisy unsharp measurements incorporated in quantum information protocols may hinder
performance, reducing the quantum advantage. However, we show that, unlike projective …

Entanglement subject to noise cannot be shielded against decaying. But, in case of many
noisy channels, the degradation can be partially prevented by using local unitary operations …

The non-Markovian depolarizing channel is explored from the perspective of understanding
its non-Markovian behaviour as well as the occurrence of singularities. The study brings …
