I. It is expected that Majorana 1 chip will enable quantum computing.

II. Majorana 1 chip has been introduced by Amazon Web Services (AWS).

III. Deep learning is a subset of machine learning.

Which of the statements given above are correct?

  1. (a) I and II only
  2. (b) II and III only
  3. (c) I and III onlyCorrect answer
  4. (d) I, II and III

Solution.

Answer: (c) I and III only

  1. Statement I is correct: unveiled in February 2025, the Majorana 1 chip is the world's first quantum processor powered by a Topological Core (using indium arsenide and aluminum topoconductors) designed to scale to a million topological qubits for fault-tolerant quantum computing.
  2. Statement II is incorrect: the Majorana 1 chip was developed and unveiled by Microsoft, not Amazon Web Services (AWS introduced the 'Ocelot' quantum chip).
  3. Statement III is correct: deep learning (multi-layered artificial neural networks) is a specialized subset of machine learning.
