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…
Conservation of angular momentum on a single-photon level
Lea Kopf, Rafael Barros, Shashi Prabhakar +2
Identifying conservation laws is central to every subfield of physics, as they illuminate the underlying symmetries and fundamental principles. A prime example can be found in quan…
Distribution of lowest eigenvalue in -body bosonic random matrix ensembles
N. D. Chavda, Priyanka Rao, V. K. B. Kota +1
We present numerical investigations demonstrating the result that the distribution of the lowest eigenvalue of finite many-boson systems (say we have number of bosons) with …
Enhancing key rates of QKD protocol by Coincidence Detection
Tanya Sharma, Rutvij Bhavsar, Jayanth Ramakrishnan +4
In theory, quantum key distribution (QKD) provides unconditional security; however, its practical implementations are susceptible to exploitable vulnerabilities. This investigation…
Hybrid Quantum Repeaters with Ensemble-based Quantum Memories and Single-spin Photon Transducers
Fenglei Gu, Shankar G Menon, David Maier +5
Reliable quantum communication over hundreds of kilometers is a daunting yet necessary requirement for a quantum internet. To overcome photon loss, the deployment of quantum repeat…
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…
