Binegativity of two qubits under noise
Sk Sazim, Natasha Awasthi
Recently, it was argued that the binegativity might be a good quantifier of entanglement for two-qubit states. Like the concurrence and the negativity, the binegativity is also ana…
Tight upper bound for the maximal expectation value of the Mermin operators
Mohd Asad Siddiqui, Sk Sazim
The violation of the Mermin inequality (MI) for multipartite quantum states guarantees the existence of nonlocality between either few or all parties. The detection of optimal MI v…
Coherence of quantum channels
Chandan Datta, Sk Sazim, Arun K. Pati +1
We investigate the coherence of quantum channels using the Choi-Jamiołkowski isomorphism. The relation between the coherence and the purity of the channel respects a duality relati…
Mutual Uncertainty, Conditional Uncertainty and Strong Sub-Additivity
Sk Sazim, Satyabrata Adhikari, Arun K. Pati +1
We introduce a new concept called as the mutual uncertainty between two observables in a given quantum state which enjoys similar features like the mutual information for two rando…
