Quantum enhanced precision in a collective measurement
H. M. Bharath, Saikat Ghosh
We explore the role of on precision in estimation of a single parameter. Collective measurements are represented by observables which commute wit…
Classical simulation of entangled states
H. M. Bharath, V. Ravishankar
Description of nonclassicality of states has hitherto been through violation of Bell inequality and non-separability, with the latter being a stronger constraint. In this paper, we…
A model independent approach towards resource count and precision limits in a general measurement
H. M. Bharath, Saikat Ghosh
A formulation towards quantifying resource count used in a measurement, that is independent of the model of the measurement dynamics(Quantum/Classical), is considered. For any gene…
Classical simulation of partially entangled states
H. M. Bharath, V. Ravishankar
We investigate the possibility of simulating partially entangled two qubit states by separable states of higher spins. First, we show that all partially entangled isotropic states…
