Why in news?

The cabinet committee approved the national quantum mission (NQM) for indigenous development of quantum technologies.

What are quantum computers?

  • Quantum computers are machines that use the properties of quantum physics to store data and perform computations.
  • Conventional or traditional computers can use either 0 or 1 at a time where as quantum computers can use both 0 and 1 simultaneously.
  • Quantum computers use the properties of Superposition and Quantum entanglement to exist in 0 and 1 state simultaneously.
  • Quantum computers can be 60 per cent 0 and 40 per cent 1 at the same time, or any other combination.
  • Conventional computers follow a two-bit system where it can exist in any of the following state such as (0,0), (0,1), (1,0) and (1,1) but only one at a time.
  •  Quantum computers follow q-bit system where it can exist at all 0r any combination of (0,0), (0,1), (1,0) and (1,1).

What are the key features of the NQM?

  • Aim - The mission allows Indian scientists to develop indigenous technology, systems, devices, and materials required to propel research and development in quantum technology.
  • Targets - To develop intermediate-scale quantum computers with 50-1,000 physical qubits in various platforms like superconducting and photonic technology.

Just like a binary bit is the basic unit of information in classical (or traditional) computing, a qubit (or quantum bit) is the basic unit of information in quantum computing.

  • Satellite-based secure quantum communications between ground stations over a range of 2,000 kilometers within India.
  • To secure quantum communications with other countries.
  • Benefits - The mission is expected to benefit communication, health, finance, and energy, drug design and space applications.
  • Four thematic hubs (T-hub) - To be established for operating 
    • Quantum computing,
    • Quantum communication,
    • Quantum sensing and metrology, and
    • Quantum materials and devices.
  • Department of Science and Technology - Will spearhead the NQM mission.

The NQM is the only mission, wherein Indian scientists will develop their own quantum technology.

What are the challenges to quantum computers?

  • The building process is complex, time taking and expensive
  • Requirements of very cold temperatures and extreme isolation for quantum computers
  • There is a significant risk of errors
  • If the superposition breaks down, the final outcome is randomly selected from the range of possibilities

Quick facts

Science and Engineering Research Board (SERB)

  • SERB is a statutory body established by parliament via “the Science and Engineering Research Board Act” 2008.
  • SERB promotes basic research in Science and Engineering.
  • SERB provides financial assistance to persons engaged in such research, academic institutions, research and development laboratories, industrial concerns and other agencies.
  • SERB is under department of science and technology.
