Quantum Limits on the Capacity of Multispan Links with Phase-Sensitive Amplification
Karol Łukanowski, Marcin Jarzyna, Konrad Banaszek
The capacity of a linear attenuating optical channel with the signal regenerated using quantum-limited phase-sensitive amplifiers is analyzed for conventional and generalized detec…
