Unambiguous joint detection of spatially separated properties of a single photon in the two arms of an interferometer
Surya Narayan Sahoo, Sanchari Chakraborti, Som Kanjilal +3
The quantum superposition principle implies that a particle entering an interferometer evolves by simultaneously taking both arms. If a non-destructive, minimally-disturbing intera…
Relating an entanglement measure with statistical correlators for two-qudit mixed states using only a pair of complementary observables
Simanraj Sadana, Som Kanjilal, Dipankar Home +1
We focus on characterizing entanglement of high dimensional bipartite states using various statistical correlators for two-qudit mixed states. The salient results obtained are as f…
Quantum computers to test fundamental physics or viceversa
Simanraj Sadana, Lorenzo Maccone, Urbasi Sinha
We present two complementary viewpoints for combining quantum computers and the foundations of quantum mechanics. On one hand, ideal devices can be used as testbeds for experimenta…
Comment on "Observing the "quantum Cheshire cat" effect with noninvasive weak measurement''
Surya Narayan Sahoo, Dipankar Home, Alex Matzkin +1
In a very recent work [arXiv:2004.07451], Kim et al claimed to have made the first genuine experimental observation of the Quantum Cheshire Cat effect. We dispute this claim on the…
Quantum State Interferography
Surya Narayan Sahoo, Sanchari Chakraborti, Arun K. Pati +1
Quantum State Tomography (QST) has been the traditional method for characterization of an unknown state. Recently, many direct measurement methods have been implemented to reconstr…
qkdSim: An experimenter's simulation toolkit for QKD with imperfections, and its performance analysis with a demonstration of the B92 protocol using heralded photon
Rishab Chatterjee, Kaushik Joarder, Sourav Chatterjee +2
Quantum Key Distribution (QKD) is one of the most important aspects of quantum cryptography. Using laws of quantum mechanics as the basis for security, the key distribution process…
