49^th Intl. Nathiagali Summer College

Activity - I: Quantum Technologies
(24^th - 28^th June, 2024)

Quantum Technology is an emerging field of Physics and Engineering, encompassing technologies that rely on the properties of quantum mechanics, especially quantum superposition and quantum entanglement. Quantum technology is a potentially disruptive discipline with the ability to affect many human activities. Quantum technology is grouped into three broad categories: Quantum Communication, Quantum Sensing and Quantum Computing.

Fast and secure sharing of information is the prime concerns of almost any communication system. The primary application of quantum communication technology is security against eavesdroppers, primarily through a method known as quantum key distribution (QKD). The commonly used cryptographic algorithms cannot provide unconditional security. Quantum Key Distribution (QKD) offers an exceptional means to this end. Quantum Communication is now an emerging field of technology with Quantum Key Distribution over planetary distances. Quantum entangled state, a mystery in itself, has proved to be a vital resource for the Quantum Key distribution protocols in free space. Quantum communication, will soon revolutionize the technical and scientific scenario in entirely unforeseeable ways.

Quantum sensing and metrology is the most mature quantum technology area, which improves timing, sensing or imaging. For example, atomic clocks from the first quantum revolution have been part of the Global Positioning System (GPS) for almost half a century. Quantum sensing stands for all quantum technologies that measure various physical variables such as external magnetic or electric fields, gravity gradient, acceleration and rotation. Quantum sensors can produce very precise information about an electric signal, magnetic anomalies and for inertial navigation. Quantum imaging systems are a wide area covering 3D quantum cameras, behind-the corner cameras, low brightness imaging and Quantum RADAR or LiDAR.

Quantum computing is one of its most profound manifestation. Quantum computer is one of the most important and groomed breaking discovery of the present age. Quantum computers could outperform their classical counterparts in certain complex computational tasks with exceptionally high speed. Specific problems that are entirely infeasible to solve on a standard computer could become feasible on a quantum computer. The 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.

During the 49th International Nathiagali Summer College, some highlights of this emerging field of Quantum Technology will be discussed.
