DESCRIPTION:IQC Alum Lecture Series: Urbasi Sinha\, Raman Research Institute\n\nWe cover different interesting aspects of experimental photonic quantum information processing that have been recently explored at the Quantum Information and Computing lab at RRI\, Bangalore. We discuss our experiment on the first loophole free violation of the Leggett Garg Inequalities (LGI) as well as the Wigner form of the same (WLGI)[1]. We then talk about our new quantum state estimation method\, which we call Quantum State Interferography[2]\, that has a fantastic scaling advantage over conventional quantum state tomography techniques with increasing system dimensions. We then discuss recent results from the lab in the domain of entanglement quantification in higher dimensional quantum information processing [3\,4\,5]and our photonic experiment that serves as a direct determination of entanglement monotones [4]. We end with touching upon our recent work on testing quantum foundations with quantum computers [6].\n[1] Loophole free interferometric test of macrorealism using heralded single photons\, K.Joarder\, D.Saha\, D.Home\, U.Sinha\, PRX Quantum\, 3\, 010307\, 2022.\n[2] Quantum State Interferography\, S.Sahoo\, S.
