Local sum uncertainty relations for angular momentum operators of bipartite permutation symmetric systems
I. Reena, H. S. Karthik, J. Prabhu Tej +3
We show that violation of variance based local sum uncertainty relation (LSUR) for angular momentum operators of a bipartite system, proposed by Hofmann and Takeuchi~[Phys.Rev.A {\…
Sum Uncertainty Relations: Uncertainty Regions for Qubits and Qutrits
Seeta Vasudevrao, I. Reena, Sudha +2
We investigate the notion of uncertainty region using the variance based sum uncertainty relation for qubits and qutrits.We compare uncertainty region of the qubit (a 2-level syste…
Heat exchange and fluctuation in Gaussian thermal states in the quantum realm
A R Usha Devi, Sudha, A. K. Rajagopal +1
The celebrated exchange fluctuation theorem -- proposed by Jarzynski and Wózcik, (Phys Rev. Lett. 92, 230602 (2004)) for heat exchange between two systems in thermal equilibrium at…
Quantum hypothesis testing and state discrimination
J. Prabhu Tej, Syed Raunaq Ahmed, A. R. Usha Devi +1
This expository article gives an overview of the theory of hypothesis testing of quantum states in finite dimensional Hilbert spaces. Optimal measurement strategy for testing binar…
Possibility of Entanglement at LIGO!
Partha Ghose, A. K. Rajagopal
It is shown that a linearized classical gravity wave {\em la} Einstein can get entangled with an array of test masses in a plane perpendicular to its direction of propaga…
N term pairwise correlation inequalities, steering and joint measurability
H. S. Karthik, A. R. Usha Devi, J. Prabhu Tej +3
Chained correlation inequalities involving pairwise correlations of qubit observables in the equatorial plane are constructed based on the positivity of a sequence of moment matric…
