Entropic uncertainty assisted by temporal memory
H. S. Karthik, A. R. Usha Devi, J. Prabhu Tej +1
The uncertainty principle brings out intrinsic quantum bounds on the precision of measuring non-commuting observables. Statistical outcomes in the measurement of incompatible obser…
From the sandwiched quantum relative Tsallis entropy to its conditional form: Separability criterion beyond local and global spectra
A. K. Rajagopal, Sudha, Anantha S Nayak +1
The quantum relative Renyi entropy of two density matrices was recently extended when the two do not commute, from which a conditional entropy is identified. This is here extended…
Equivalence of classicality and separability based on P phase-space representation of symmetric multiqubit states
A R Usha Devi, A K Rajagopal, Sudha +2
Classical and quantum world views differ in peculiar ways. Understanding decisive quantum features -- for which no classical explanation exist -- and their interrelations is of fou…
Inversion of moments to retrieve joint probabilities in quantum sequential measurements
H. S. Karthik, Hemant Katiyar, Abhishek Shukla +3
A sequence of moments encode the corresponding probability distribution. Probing if quantum joint probability distribution can be retrieved from the associated set of moments -- re…
