Nonclassicality in off-resonant Raman process
Kishore Thapliyal, Jan Pe{ř}ina
Raman process is used for generation of nonclassical states and subsequent applications due to its simplicity. In view of the experimental feasibility of the off-resonant Raman pro…
Interaction of light and semiconductor can generate quantum states required for solid state quantum computing: Entangled, steered and other nonclassical states
Arjun Mukherjee, Biswajit Sen, Kishore Thapliyal +2
Proposals for solid state quantum computing are extremely promising as they can be used to built room temperature quantum computers. If such a quantum computer is ever built it wou…
Quantum Zeno effect and nonclassicality in a PT symmetric system of coupled cavities
Javid Naikoo, Kishore Thapliyal, Subhashish Banerjee +1
The interplay between the nonclassical features and the parity-time (PT) symmetry (or its breaking) is studied here by considering a PT symmetric system consisting of two cavities…
Comparing coherence measures for X states: Can quantum states be ordered based on quantum coherence?
Sandeep Mishra, Kishore Thapliyal, Anirban Pathak +1
Quantum coherence is an essential resource for quantum information processing and various quantitative measures of it have been introduced. However, the interconnections between th…
Lower- and higher-order nonclassical properties of photon added and subtracted displaced Fock states
Priya Malpani, Nasir Alam, Kishore Thapliyal +3
Nonclassical properties of photon added and subtracted displaced Fock states have been studied using various witnesses of lower- and higher-order nonclassicality. Compact analytic…
Quantum e-commerce: A comparative study of possible protocols for online shopping and other tasks related to e-commerce
Kishore Thapliyal, Anirban Pathak
A set of quantum protocols for online shopping is proposed and analyzed to establish that it is possible to perform secure online shopping using different types of quantum resource…
A theoretical study of nonclassical effects in optical and spin systems and their applications
Kishore Thapliyal
Nonclassical states, having no classical analogue, promise advantage in the performance in several fields of technology, such as computation, communication, sensing. This led to an…
Kak's three-stage protocol of secure quantum communication revisited: Hitherto unknown strengths and weaknesses of the protocol
Kishore Thapliyal, Anirban Pathak
Kak's three-stage protocol for quantum key distribution is revisited with special focus on its hitherto unknown strengths and weaknesses. It is shown that this protocol can be used…
