Classical capacity of quantum non-Gaussian attenuator and amplifier channels
Zacharie Van Herstraeten, Saikat Guha, Nicolas J. Cerf
We consider a quantum bosonic channel that couples the input mode via a beam splitter or two-mode squeezer to an environmental mode that is prepared in an arbitrary state. We inves…

Majorization theoretical approach to entanglement enhancement via local filtration
Zacharie Van Herstraeten, Nicolas J. Cerf, Saikat Guha +1
From the perspective of majorization theory, we study how to enhance the entanglement of a two-mode squeezed vacuum (TMSV) state by using local filtration operations. We present se…
