Indigenous Quantum Key Distribution (QKD) solution by C-DOT
Recently the Center for Development of Telematics (C-DOT) has unveiled an indigenously developed Quantum Key Distribution (OKD) solution.
- The development of indigenous OKD solution will lead to rapid advances in quantum computing. It is noteworthy that this progress will help to address the security threats to the data being transmitted by the current communication infrastructure.
- The QKD solution, developed by C-DOT, can cover distances of over 100 kilometers over standard optical fiber.
- Quantum computing focuses on developing computer technology based on quantum law principles. This theory explains the nature and behavior of energy and matter at the quantum (atomic and subatomic) level.
- Classical computers process information in a binary format, called bits. Bits represent either 0 or 1. In contrast, a quantum computer uses quantum bits or qubits to encode information as 0 or 1 or both at the same time.
They operate in accordance with the following two major principles of quantum physics:
- Superposition means that each qubit can represent both 1 and 0 at the same time.
- Entanglement means that the qubits in a superposition can be correlated with each other. That is, the position of one (whether it is 1 or 0) may depend on the position of the other.
Quantum technologies can be mainly divided into the following areas: quantum computing, quantum communication, quantum sensors and quantum materials.
Some other initiatives taken in India related to quantum technologies:
National Mission on Quantum Technologies and Applications: Rs 8,000 crore has been allocated for this mission in the budget of 2020 for a period of five years.
Quantum Communication Laboratory has been inaugurated at C-DOT, Delhi. The Prime Minister’s Science, Technology and Innovation Advisory Council (PM-STIAC) has launched the Quantum Frontier Mission.
