Activity - IV: Quantum Technologies
(23^rd - 28^th June, 2025)

Quantum technologies are an emerging field that applies the principles of quantum mechanics to create innovative tools, systems, and processes. These technologies leverage phenomena like superposition, entanglement and quantum tunneling to achieve capabilities beyond the limits of classical systems. Quantum Technologies provides advantages of Unmatched Computing Power leading to tackling of problems previously considered unsolvable, Ultra-Secure Communication providing Virtually un-hackable systems and Precision creating highly accurate sensors for real-world applications.

With the development of Quantum Computers, and with the availability of tremendous computational and data processing potential, almost all of the hard or intractable scientific, technological and engineering problem will become potentially manageable within no time and, hence will open unimaginable new vistas for technical innovations along with the real time simulations of the complex, multiplayer strategic situations.

Similarly, on the forefronts of data security and uninterrupted, reliable, and entirely secure communications, the quantum cryptography has, by now, turned into a mature technology with the establishment and demonstration of an efficient quantum mechanically backed secure channel among the earth and the satellites. For the next phase, i.e. for quantum direct communications, quantum multiparty communicational webs and quantum internet both theoretical and experimental research is underway right now.

Furthermore, teleportation is no more a science fictions theme and the quantum teleportation has successfully demonstrated its potential for instantaneous transportation of basic features of one quantum entity to the other spatio-temporally separated quantum system without invoking any material channel between them. Same is the status of lot many other current technologies including sensors and time/frequency standards, all of which will improve many orders of magnitude in precision. The portable gravimeter based on quantum interference of specifically engineered atomic samples has a precision of nGal (10-9) and it is capable of detecting and diagnosing minute density changes caused by different mineral lying deep into the earth crust from the sea or earth’s surface.

A week-long activity on Quantum Technologies will serve as an intellectual bridge to join the scientific community of the subject and help to cope with the stringent needs and challenges presented by this fascinating and somewhat mystifying subject.
