Non-Markovianity and entanglement detection

Sourav Chanduka, Bihalan Bhattacharya, Rounak Mundra +2

We have established a novel method to detect non-Markovian indivisible quantum channels using structural physical approximation. We have shown that this method can be used to detec…

Generating and detecting bound entanglement in two-qutrits using a family of indecomposable positive maps

Bihalan Bhattacharya, Suchetana Goswami, Rounak Mundra +4

The problem of bound entanglement detection is a challenging aspect of quantum information theory for higher dimensional systems. Here, we propose an indecomposable positive map fo…

Broadcasting of NPT Entanglement in Two Qutrit Systems

Rounak Mundra, Sabuj Chattopadhyay, Indranil Chakrabarty +1

It is known that beyond and dimensional quantum systems, Peres-Hordecki criterion is no longer sufficient as an entanglement detection criterion as ther…

Quantumness of Relative Incompatibility

Manish Kumar Shukla, Rounak Mundra, Arun K Pati +2

We propose a new measure of relative incompatibility for a quantum system with respect to two non-commuting observables, and call it quantumness of relative incompatibility. In cas…

Broadcasting of quantum correlations in qubit-qudit systems

Rounak Mundra, Dhrumil Patel, Indranil Chakrabarty +2

Quantum mechanical properties like entanglement, discord and coherence act as fundamental resources in various quantum information processing tasks. Consequently, generating more r…
