Increasing distillable key rate from bound entangled states by using local filtration
Mayank Mishra, Ritabrata Sengupta, Arvind
We show the enhancement of distillable key rate for quantum key distribution(QKD), by local filtering, for several bound entangled states. Through our work it becomes evident that…

Optimal characterization of Gaussian channels using photon-number-resolving detectors
Chandan Kumar, Ritabrata Sengupta, Arvind
We present optimal schemes, based on photon number measurements, for Gaussian state tomography and for Gaussian process tomography. An -mode Gaussian state is completely specifi…
