The Indian government approved the National Quantum Mission in April 2023 with a budget of Rs 6,003 crore. The mission’s goal is to develop Quantum Technology (QT) through scientific and industrial research and development. India will be the sixth country to have a dedicated quantum mission after the USA, Austria, Finland, France, and China. The mission will define milestones to be achieved over eight years (2023-24 to 2030-31). The Hans India spoke to faculty members at the Centre for Quantum Science and Technology (CQST), Indian Institute of Information Technology (IIIT) Hyderabad to learn more about quantum computers and the mission.
Professor Harjinder Singh explained that classical computers struggle to handle complex problems and large amounts of data. Quantum computing utilizes quantum bits or qubits, which can represent data as either 0, 1, or both simultaneously through superposition. Qubits have the unique ability to exist in multiple states simultaneously, allowing quantum computers to undertake complex calculations. Another key difference between quantum and classical computing is entanglement, where qubits can become entangled, meaning changes in one qubit can instantaneously affect the entangled qubits.
Dr Shantanav Chakraborty explained that conventional computers work on the principle of classical physics, while quantum computers obey the principles of small particles such as atoms and molecules. Indian research institutions such as IISER Pune, scientists from two Ahmedabad based laboratories, and the industry in India are taking steps for quantum technologies.
Dr. Indranil Chakrabarty suggested that scientists working in different educational institutions in Hyderabad can come together to work on quantum computing.
