Joint measurability, steering and entropic uncertainty
H. S. Karthik, A. R. Usha Devi, A. K. Rajagopal
The notion of incompatibility of measurements in quantum theory is in stark contrast with the corresponding classical perspective, where all physical observables are jointly measur…
Joint Measurability and Temporal Steering
H. S. Karthik, J. Prabhu Tej, A. R. Usha Devi +1
Quintino et. al. (Phys. Rev. Lett. 113, 160402 (2014)) and Uola et. al. (Phys. Rev. Lett. 113, 160403 (2014)) have recently established an intrinsic relation between non-joint meas…
Quantum which-way information and fringe visibility when the detector is entangled with an ancilla
J. Prabhu Tej, A. R. Usha Devi, H. S. Karthik +2
Quantum mechanical wave-particle duality is quantified in terms of a trade-off relation between the fringe visibility and the which-way distinguishability in an interference experi…
