Investigate the effects of the existence of correlation between two consecutive use of the quantum channel on quantum speed limit time
N. Awasthi, S. Haseli, U. C Johri +3
Memory effects play an important role in the theory of open quantum systems. There are two completely independent insights about memory for quantum channels. In quantum information…
Effect of correlated noise channels on quantum speed limit
Natasha Awasthi, U. C. Johri
We study the effect of correlated Markovian noise channels on the quantum speed limit of an open system. This is done for correlated dephasing and amplitude damping channels for a…
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…
Universal quantum uncertainty relations between non-ergodicity and loss of information
Natasha Awasthi, Samyadeb Bhattacharya, Aditi Sen De +1
We establish uncertainty relations between information loss in general open quantum systems and the amount of non-ergodicity of the corresponding dynamics. The relations hold for a…
