Direct measurement of atomic entanglement via cavity photon statistics
Nilakantha Meher, M. Bhattacharya, Anand K. Jha
We propose an experimental scheme for the measurement of entanglement between two two-level atoms. Our scheme requires one of the two entangled atoms to interact with a cavity fiel…
Propagation-induced entanglement revival
Abhinandan Bhattacharjee, Mritunjay K. Joshi, Suman Karan +2
The practical implementation of free-space quantum information tasks requires entanglement to be sustained over long distances and in the presence of turbulent and noisy environmen…
Measurement of two-photon position-momentum EPR correlations through single-photon intensity measurements
Abhinandan Bhattacharjee, Nilakantha Meher, Anand K. Jha
The measurement of the position-momentum EPR correlations of a two-photon state is important for many quantum information applications ranging from quantum key distribution to coin…
Dependence of the photon statistics of down-converted field-modes on the photon statistics of pump field-mode
Nilakantha Meher, Anand K. Jha
Using the zero time-delay second-order correlation function for studying the photon statistics, we investigate how the photon statistics of the field-modes generated by parametric…
Intrinsic degree of coherence of two-qubit states and measures of two-particle quantum correlations
Nilakantha Meher, Abu Saleh Musa Patoary, Girish Kulkarni +1
Recently, a basis-invariant measure of coherence known as the intrinsic degree of coherence has been established for classical and single-particle quantum states [JOSA B {\bf 36},…
Intrinsic degree of coherence of classical and quantum states
Abu S Musa Patoary, Girish Kulkarni, Anand K. Jha
In the context of the 2-dimensional (2D) polarization states of light, the degree of polarization P2 is equal to the maximum value of the degree of coherence over all possible base…
