A projection-free approach toward mapping the structured polarization fields
Sandeep Singh, G. K. Samanta
We present a projection-free method for mapping two-dimensional polarization distributions using Hong-Ou -Mandel (HOM) interference. Conventional polarization characterization tech…

Fast measurement of group index variation with ultimate precision using Hong-Ou-Mandel interferometry
Sandeep Singh, Vimlesh Kumar, G. K. Samanta
Hong-Ou-Mandel (HOM) interferometry has emerged as a valuable tool for quantum sensing applications, particularly in measuring physical parameters that influence the relative optic…

Beamsplitter-free, high bit-rate, quantum random number generator based on temporal and spatial correlations of heralded single-photons
Ayan Kumar Nai, Amritash Sharma, Vimlesh Kumar +4
The spontaneous parametric down-conversion (SPDC), an inherently random quantum process, produces a non-deterministic photon-pair with strong temporal and spatial correlations owin…
