Probing nonclassicality in an optically-driven cavity with two atomic ensembles
Javid Naikoo, Kishore Thapliyal, Anirban Pathak +1
The possibility of observing nonclassical features in a physical system comprised of a cavity with two ensembles of two-level atoms has been investigated by considering different c…
Nonclassicality in non-degenerate hyper-Raman processes
Kishore Thapliyal, Anirban Pathak, Biswajit Sen +1
A perturbative analytic operator solution of a completely quantum mechanical Hamiltonian of multi-photon pump non-degenerate hyper-Raman process is obtained. It is shown that the o…
Lower- and higher-order nonclassicality in a Bose-condensed optomechanical-like system and a Fabry-Perot cavity with one movable mirror: squeezing, antibunching and entanglement
Nasir Alam, Kishore Thapliyal, Anirban Pathak +3
Various lower- and higher-order nonclassical properties have been studied for two physical systems- (i) an optomechanical system composed of a Fabry-Perot cavity with one nonlinear…
Comparison of lower order and higher order nonclassicality in photon added and photon subtracted squeezed coherent states
Kishore Thapliyal, Nigam Lahiri Samantray, J. Banerji +1
Nonclassical properties of photon added and photon subtracted squeezed coherent states have been compared with specific focus on the higher order nonclassicalities, such as higher…
Design and experimental realization of an optimal scheme for teleportion of an -qubit quantum state
Mitali Sisodia, Abhishek Shukla, Kishore Thapliyal +1
An explicit scheme (quantum circuit) is designed for the teleportation of an -qubit quantum state. It is established that the proposed scheme requires an optimal amount of quant…
Semi-quantum communication: Protocols for key agreement, controlled secure direct communication and dialogue
Chitra Shukla, Kishore Thapliyal, Anirban Pathak
Semi-quantum protocols that allow some of the users to remain classical are proposed for a large class of problems associated with secure communication and secure multiparty comput…
General structures of reversible and quantum gates
Kishore Thapliyal, Anirban Pathak
The most general structure (in matrix form) of a single-qubit gate is presented. Subsequently, used that to obtain a set of conditions for testing (a) whether a given 2-qubit gate…
Quantum Conference
Anindita Banerjee, Kishore Thapliyal, Chitra Shukla +1
A notion of quantum conference is introduced in analogy with the usual notion of a conference that happens frequently in today's world. Quantum conference is defined as a multipart…
