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…
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…
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…
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…
Bright entangled photon source without stringent crystal temperature and laser frequency stabilization
Sandeep Singh, Vimlesh Kumar, Anirban Ghosh +1
Entangled photon sources (EPS), the major building block for a variety of quantum communication protocols, are commonly developed by utilizing the spontaneous parametric down-conve…
Imaging inspired characterization of single photons carrying orbital angular momentum
Vimlesh Kumar, Varun Sharma, Sandeep Singh +4
We report on an imaging-inspired measurement of orbital angular momentum (OAM) using only a simple tilted lens and an Intensified Charged Coupled Device (ICCD) camera, allowing us…
