Classical-to-quantum transfer of geometric phase for non-interferometric phase measurement and manipulation of quantum state
Vimlesh Kumar, Chahat Kaushik, M. Ebrahim-Zadeh +2
The geometric phase, originating from the cyclic evolution of a state, such as polarization on the Poincaré sphere, is typically measured through interferometric approaches that of…

Near-video frame rate quantum sensing using Hong-Ou-Mandel interferometry
Sandeep Singh, Vimlesh Kumar, Varun Sharma +2
Hong-Ou-Mandel (HOM) interference, the bunching of two indistinguishable photons on a balanced beam-splitter, has emerged as a promising tool for quantum sensing. There is a need f…
