Monogamy of quantum correlations - a review
Himadri Shekhar Dhar, Amit Kumar Pal, Debraj Rakshit +2
Monogamy is an intrinsic feature of quantum correlations that gives rise to several interesting quantum characteristics which are not amenable to classical explanations. The monoga…
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…
Necessarily transient quantum refrigerator
Sreetama Das, Avijit Misra, Amit Kumar Pal +2
We show that one can construct a quantum absorption refrigerator that provides refrigeration only in the transient regime, by using three interacting qubits, each of which is also…
Static and dynamical quantum correlations in phases of an alternating field XY model
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
We investigate the static and dynamical patterns of entanglement in an anisotropic XY model with an alternating transverse magnetic field, which is equivalent to a two-component on…
Conclusive Identification of Quantum Channels via Monogamy of Quantum Correlations
Asutosh Kumar, Sudipto Singha Roy, Amit Kumar Pal +3
We investigate the action of local and global noise on monogamy of quantum correlations, when monogamy scores are considered as observables, and three-qubit systems are subjected t…
