Sequential Neural Probabilistic Amplitude Shaping: Learning the Channel's Language

Mohammad Taha Askari, Lutz Lampe, Amirhossein Ghazisaeidi

We present the first neural probabilistic amplitude shaping that outperforms existing methods while accounting for all implementation losses, using a block-less, easily implementab…

Optimization of CV-QKD Under Practical Constraints

Svitlana Matsenko, Amirhossein Ghazisaeidi, Marcin Jarzyna +2

Using reinforcement learning, we optimize for practical hardware constraints, including limited FIR filter taps at the transmitter and receiver, mean photon number and finite DAC/A…

Neural Probabilistic Amplitude Shaping for Nonlinear Fiber Channels

Mohammad Taha Askari, Lutz Lampe, Amirhossein Ghazisaeidi

We introduce neural probabilistic amplitude shaping, a joint-distribution learning framework for coherent fiber systems. The proposed scheme provides a 0.5 dB signal-to-noise ratio…

Accurate and Effective Model for Coexistence of Classical and Quantum Signals In Optical Fibers

Lucas Alves Zischler, Çağla Özkan, Tristan Vosshenrich +10

The rising interest in quantum-level communication has resulted in proposals for coexistence schemes with classical signals within the same fiber optic channel, where the most rece…

Neural Probabilistic Shaping: Joint Distribution Learning for Optical Fiber Communications

Mohammad Taha Askari, Lutz Lampe, Amirhossein Ghazisaeidi

We present an autoregressive end-to-end learning approach for probabilistic shaping on nonlinear fiber channels. Our proposed scheme learns the joint symbol distribution and provid…
