Decoherence Dynamics of Measurement-Induced Nonlocality and comparison
with Geometric Discord    [PDF]

Ajoy Sen, Debasis Sarkar, Amit Bhar

We check the decoherence dynamics of Measurement-induced Nonlocality and compare it with geometric discord. There are quantum states, on which the action of dephasing channel cannot destroy MIN in finite or infinite time. We also investigate the additive dynamics of MIN on a qubit state under two independent noise. Geometric discord also follows such additive dynamics like quantum discord.
