PQI Seminar: "Quantum Advantage in Optical Laser Communications using NISQ-era Quantum Processors"

This is a past event.

Quantum Advantage in Optical Laser Communications using NISQ-era Quantum Processors

Presenter:
Dr. Kaushik Seshadreesan, Assistant Professor, Department of Informatics and Networked Systems

Abstract: Optical laser communication forms a cornerstone of modern-day data communications. In the quantum-limited regime of lasercom, where the received optical signal power is small, e.g., in deep-space communications, pre-detection quantum domain collective processing of blocks of received signal pulses corresponding to communication codewords can provide enhanced communication capacity. We present a novel quantum receiver design methodology based on a quantum belief propagation algorithm that attains such enhancement. I will discuss the receiver design and the feasibility of implementing the receiver using noisy intermediate-scale non-error-corrected quantum processors of the type currently being developed in the quantum computing industry.

Bio: Dr. Seshadreesan is an Assistant Professor at the University of Pittsburgh, in the Department of Informatics and Networked Systems, School of Computing and Information. Kaushik obtained his Ph.D. in Physics from Louisiana State University under the supervision of Jonathan P. Dowling with a dissertation at the interface of quantum optics and quantum information and estimation theories. Kaushik then held postdoctoral and research scientist positions at the Max Planck Institute for the Science of Light, and the Wyant College of Optical Sciences at the University of Arizona before joining U. Pittsburgh in the fall of 2021. Kaushik holds an M.Sc. in Physics and B.E. in Electrical and Electronics Engineering from Birla Institute of Technology and Science, Pilani, India. Kaushik's research broadly lies in quantum information science and technologies spanning quantum computing, quantum sensing, and quantum communications.
