National Quantum Mission (NQM)

What is the National Quantum Mission (NQM)?

The National Quantum Mission (NQM) is India’s first dedicated mission for the development of quantum technologies. It was approved by the Union Cabinet in April 2023 and is being implemented by the Department of Science and Technology (DST), Ministry of Science and Technology.

The mission aims to create a complete quantum technology ecosystem covering research, innovation, indigenous hardware manufacturing, skilled manpower, and commercialization.

It forms an important pillar of Digital India, Atmanirbhar Bharat, Make in India, Startup India, and the vision of Viksit Bharat 2047.

What is Quantum Computing?

Quantum computing is an advanced computing technology that utilizes the principles of Quantum Mechanics instead of classical electronics.

Unlike conventional computers that use Bits, quantum computers process information using Quantum Bits (Qubits).

Classical Computer A classical bit can exist in only one state:

Quantum Computer A qubit can exist in:

0
1
Both 0 and 1 simultaneously (Superposition)

This enables quantum computers to process an enormous number of calculations simultaneously.

Fundamental Principles of Quantum Computing

1. Superposition

Superposition allows a qubit to exist in multiple states simultaneously until it is measured.

This dramatically increases computational power.

2. Entanglement

Entanglement is a phenomenon where two or more qubits become interconnected.

Changing one qubit instantly influences the other irrespective of distance.

Einstein famously described it as:

“Spooky action at a distance.”

3. Quantum Interference

Quantum interference amplifies correct computational pathways while suppressing incorrect ones, improving computational efficiency.

What is Quantum Advantage?

Quantum Advantage refers to the point where a quantum computer performs a specific computational task:

Faster
More accurately
More efficiently
At lower cost

than the world’s most powerful classical supercomputers.

The recent achievement by BITS Pilani and IBM Quantum represents an important step toward demonstrating practical Quantum Advantage. (Read Full Article Here)

Major Components of the National Quantum Mission
