Scale-invariant freezing of entanglement
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We show that bipartite entanglement in a one-dimensional quantum spin model undergoing time-evolution under local Markovian environments can be frozen over time. We demonstrate thi…
Activation of Nonmonogamous Multipartite Quantum States
Saptarshi Roy, Tamoghna Das, Asutosh Kumar +2
The monogamy relation for quantum correlations is not satisfied by all measures for all multiparty quantum states. We prove that an arbitrary quantum state which is nonmonogamous f…
Masking quantum information is impossible
Kavan Modi, Arun Kumar Pati, Aditi Sen De +1
Classical information encoded in composite quantum states can be completely hidden from the reduced subsystems and may be found only in the correlations. Can the same be true for q…
