Quantum sensing through bosonic-fermionic Bell-state transitions in two-photon interference
Chahat Kaushik, Vimlesh Kumar, G. K. Samanta
Hong-Ou-Mandel (HOM) interference has become a central resource for quantum sensing and metrology owing to its sensitivity to temporal delay and photon indistinguishability. Howeve…
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…
Device-independent, megabit-rate quantum random number generator with beam-splitter-free architecture and live Bell test certification
Ayan Kumar Nai, Vimlesh Kumar, M. Ebrahim-Zadeh +1
Device-independent quantum random number generators (DI-QRNGs) are crucial for information processing, ensuring certified quantumness and genuine randomness. However, existing impl…
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…
