Probing quantum correlations in non-degenerate hyper-Raman process
Moumita Das, Biswajit Sen, Ankur Sensharma +2
Possibilities of observing single mode and intermodal quantum correlations (e.g., antibunching, steering and entanglement) are studied for a probed-hyper-Raman system with specific…
Higher-order nonclassicalities in hybrid coherent states
Sandip Kumar Giri, Biswajit Sen
In the development of quantum technologies, nonclassical states have been playing a pivotal role, as quantum advantage cannot be obtained without appropriate utilization of nonclas…
