Talk Summary: Quantum computers promise exponential speedups for problems ranging from drug discovery to cryptanalysis but realizing that promise depends on solving one of the deepest challenges in physics: decoherence. When a qubit interacts with its environment, quantum coherence dissolves irreversibly into classical noise, erasing the very properties that make quantum computation powerful. This talk traces the intellectual history of Quantum Information Science, from Feynman's 1982 conjecture about quantum simulation through Shor's algorithm, quantum error correction, and the current noisy intermediate-scale quantum (NISQ) era. Along the way, it maps the field's genuinely interdisciplinary character spanning quantum mechanics, computer science, information theory, and examines the core concepts of superposition, entanglement, and interference that distinguish quantum from classical information. The talk closes with a look at the research frontier: what remains unsolved, what the NISQ era makes newly possible, and what the post-quantum cryptographic transition means for information professionals and the systems they manage.

Bio: Lalitha Nallamothula is a doctoral candidate in Information Science at the University of North Texas, conducting research at the intersection of Quantum information Science and AI&ML under the supervision of Dr. Victor Prybutok. Her dissertation investigates entropy dynamics in open quantum systems and the theoretical foundations of quantum decoherence. She brings rare industry depth to her academic work, having served as Head of Program Management for the Amazon Braket Quantum team, where she led software and technical consulting initiatives at the forefront of commercial quantum computing. She is the author of two published quantum information books and the Founder and CEO of QuantumAstra, a quantum sensing company developing compact, high-precision sensors, engineered for defense, space, electric vehicle, and energy applications. QuantumAstra is a graduate of the Duality Accelerator, the nation's premier quantum technology accelerator backed by the Chicago Quantum Exchange and was selected for Cohort 5 of the HUSTLE Defense Accelerator sponsored by the Air Force Research Laboratory.
