Revealing Incommensurability between Device-Independent Randomness, Nonlocality, and Entanglement using Hardy and Hardy-type Relations
Souradeep Sasmal, Ashutosh Rai, Sayan Gangopadhyay +2
A comprehensive treatment of the quantification of randomness certified device-independently by using the Hardy and Cabello-Liang-Li (CLL) nonlocality relations is provided in the…
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…
Entanglement protection in higher-dimensional systems
Ashutosh Singh, Urbasi Sinha
The inevitable dissipative interaction of an entangled quantum system with its environment causes degradation in quantum correlations present in the system. This can lead to a fini…
