Deep learning for enhanced free-space optical communications

no code implementations15 Aug 2022 Manon P. Bart, Nicholas J. Savino, Paras Regmi, Lior Cohen, Haleh Safavi, Harry C. Shaw, Sanjaya Lohani, Thomas A. Searles, Brian T. Kirby, Hwang Lee, Ryan T. Glasser

Atmospheric effects, such as turbulence and background thermal noise, inhibit the propagation of coherent light used in ON-OFF keying free-space optical communication.

Dimension-adaptive machine-learning-based quantum state reconstruction

no code implementations11 May 2022 Sanjaya Lohani, Sangita Regmi, Joseph M. Lukens, Ryan T. Glasser, Thomas A. Searles, Brian T. Kirby

We introduce an approach for performing quantum state reconstruction on systems of $n$ qubits using a machine-learning-based reconstruction system trained exclusively on $m$ qubits, where $m\geq n$.

Generative Machine Learning for Robust Free-Space Communication

no code implementations5 Sep 2019 Sanjaya Lohani, Ryan T. Glasser

Realistic free-space optical communications systems suffer from turbulent propagation of light through the atmosphere and detector noise at the receiver, which can significantly degrade the optical mode quality of the received state, increase cross-talk between modes, and correspondingly increase the symbol error ratio (SER) of the system.

Dispersion Characterization and Pulse Prediction with Machine Learning

no code implementations5 Sep 2019 Sanjaya Lohani, Erin M. Knutson, Wenlei Zhang, Ryan T. Glasser

In this work we demonstrate the efficacy of neural networks in the characterization of dispersive media.

Coherent Optical Communications Enhanced by Machine Intelligence

no code implementations5 Sep 2019 Sanjaya Lohani, Ryan T. Glasser

Additionally, we program the neural network system at the transmitter such that it autonomously learns to correct for the noise associated with a weak QPSK signal, which is shared with the network state of the receiver prior to the implementation of the communications.
