Generation of large Fock states from coherent states using Kerr interaction and displacement
Nilakantha Meher, Anirban Pathak, S. Sivakumar
We discuss a scheme to generate large Fock states. The scheme involves repeatedly applying an experimentally feasible unitary transformation to convert a semiclassical state into a…
A review on quantum information processing in cavities
Nilakantha Meher, S. Sivakumar
The processing of information and computation is undergoing a paradigmatic shift since the realization of the enormous potential of quantum features to perform these tasks. Coupled…
Enhancing phase sensitivity with number state filtered coherent states
Nilakantha Meher, S. Sivakumar
Number state filtered coherent states are a class of nonclassical states obtained by removing one or more number states from a coherent state. Phase sensitivity of an interferomete…
Atomic switch for control of heat transfer in coupled cavities
Nilakantha Meher, S. Sivakumar
Controlled heat transfer and thermal rectification in a system of two coupled cavities connected to thermal reservoirs are discussed. Embedding a dispersively interacting two-level…
Nonintegrability and quantum fluctuations in a quantum optical model
Nilakantha Meher, S. Sivakumar
Integrability in quantum theory has been defined in more than one ways. Recently, Braak suggested a new definition that a quantum system is integrable if the number of parameters r…
Number state filtered coherent state
Nilakantha Meher, S. Sivakumar
Number state filtering in coherent states leads to sub-Poissonian photon statistics. These states are more suitable for phase estimation when compared with the coherent states. Non…
