Referee’s Report JOSA B Manuscript ID 273944
PAPER DESCRIPTION
In the paper titled “Non-Markovian coherence and entanglement transfer in a quantum version of Newton’s cradle”, Mu and co-author have presented the quantum analog of the classical Newton’s cradle. An array of couple cavities (coupled with a common Markovian and non-Markovian environment) with nearest neighbor hopping interaction between the cavities, has been selected as the quantum cradle. In the case of quantum cradle with Markovian baths, single exception transfer is used analogously to the energy and momentum transfer among the balls of the classical cradle. Besides few subtleties the authors have shown that single excitation energy transfer through the quantum cradle follows …show more content…
The study of coupled cavity arrays in the context of quantum state and entanglement transfer is not new, however the comparison of classical and quantum version of Newton’s cradle itself is interesting, which can be useful from the perspective of fundamentals of quantum theory as well for applications in quantum information processing . Therefore, I can recommend the publication of this paper in the Journal of Optical Society of America B, provided the authors address the following questions/concerns adequately:
QUESTIONS, COMMENTS AND …show more content…
In the introduction section and later on, authors can also point out that by higher central frequency they actually mean the central frequency of the bigger cavity to be higher than the resonant frequency of the smaller cavities.
3. Authors can also mention some other physically interesting models for the non-Markovian environments such as Ohmic environments, double Lorentzian environments etc. This will give a sense to the reader that some interesting types of models are still there to be studied.
• On page 4, left column, third paragraph: I think it would be nice if authors mention that the case of |psi_ini>=1/sqrt(5)(|10000>+|01000>+|00100>+|00010>+|00001>) is particularly interesting (even though not studied here) as it is the famous multipartite W-state which is of particular interest for the quantum information scientists community.
