In a conversation with Dataquest, Dr. Akhilesh Gupta, Secretary of SERB and Senior Adviser & Head of DST, shed light on the transformative potential of quantum computing, revolutionizing the very foundations of how we process information and ensuring unprecedented levels of security in communication.


Breaking down the basics, Dr. Gupta delved into the classical binary system, emphasizing the reliance on combinations of 0s and 1s in traditional computing. Drawing an analogy to electron orbits in an atom, he illustrated how the quantum realm introduces a duality of wave and particle models, enabling particles to exist in states between 0 and 1. This quantum phenomenon opens the door to vast possibilities, condensing complex computations into remarkably concise representations.

The quantum advantage becomes apparent when considering the efficiency of operations. Dr. Gupta highlighted the ability of quantum computers to perform intricate calculations with minimal digits, as opposed to the thousands required by conventional systems. The impact extends beyond mere speed, promising a paradigm shift in the realm of communication and data security.

Using the example of quantum communication, Dr. Gupta emphasized the impenetrability of quantum-encoded information, making it impervious to decoding even by entities equipped with quantum technology. This newfound security has profound implications for diplomatic and confidential communications, with the potential to reshape international dynamics.

The implications of quantum computing extend beyond computational efficiency; they promise to redefine the very principles of physics. Dr. Gupta asserted that the advent of quantum technology heralds a transformative era, challenging our understanding of the physical world. As India positions itself at the forefront of this quantum revolution, Dr. Akhilesh Gupta's insights provide a glimpse into a future where the boundaries of computation and communication are pushed beyond the limits of what was once deemed possible. The quantum leap is not merely a technological advancement; it is a reimagining of the very fabric of our digital existence, he says.
