The Department of Mathematics in association with Aryabhatta Math club organized a Guest Lecture on “An introduction to the foundation of quantum computing” on 17.03.2026 at 02.00 PM, delivered by Dr. J. Jackson from the Department of Avionics, Indian Institute of Space Science and Technology, Department of Space, Trivandrum.
The session focused on the theme “Fundamentals and Applications of Quantum Computing”, aiming to provide students with a clear understanding of this emerging and transformative field. Dr. J. Jackson began the lecture by introducing the fundamental differences between classical and quantum computing, explaining the limitations of classical systems and the immense computational potential offered by quantum technologies.
The lecture covered essential principles of quantum mechanics, including qubits, superposition, entanglement and quantum interference. He explained how qubits differ from classical bits by existing in multiple states simultaneousl
y, enabling parallel computation. The concept of entanglement was discussed as a unique quantum phenomenon that allows qubits to be interconnected regardless of distance, significantly enhancing computational efficiency.
Dr. Jackson also introduced quantum gates such as the Hadamard and CNOT gates, explaining how they are used to manipulate qubits within quantum circuits. The structure and functioning of quantum circuits as the foundation for executing quantum algorithms were clearly illustrated.
The session further explored important quantum algorithms, including Shor’s Algorithm and Grover’s Algorithm. He demonstrated how these algorithms can outperform classical approaches, particularly in areas such as cryptography and search optimization. The potential applications of quantum computing in fields like medicine, artificial intelligence, materials science and complex system optimization were discussed in an engaging and accessible manner.
In addition, the lecture addressed the current challenges in quantum computing, such as qubit decoherence, error correction and scalability. Dr. Jackson emphasized the importance of ongoing research in developing stable and reliable quantum systems to unlock the full potential of this technology.
The lecture concluded with an encouraging message to students to explore the rapidly evolving field of quantum computing and build a strong foundation in its core principles. He highlighted that although the field is still in its early stages, it holds the power to revolutionize the future of computation.
The session was highly informative and thought-provoking, providing students with valuable insights into both the theoretical and practical aspects of quantum computing. The Department of Computer Science sincerely thanks Dr. J. Jackson for his enlightening presentation and for inspiring students to delve deeper into this cutting-edge domain. The Department also expresses its heartfelt gratitude to our Chairman Sir, Correspondent Mam, Dean Mam, and HoD Sir for their constant support and encouragement, which contributed to the successful conduct of this guest lecture. The department also thank Dr. V. Hariharan, Principal of PCE and Mrs. M. Vimala Iyr, Head of the Department, PCE, whose presence added great value to the occasion.
