Q. Consider the following statements:

UPSC Civil Services Examination (Prelims) 2025 – General Studies Paper I

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?

(a) I and II only

(b) II and III only

(c) I and III only

(d) I, II and III

Answer: (c) I and III only

Explanation:

  • Statement I – Correct
    The Majorana 1 chip is associated with research into topological quantum computing, which uses Majorana fermions to create more stable qubits. It is expected to play a significant role in the development of quantum computing by reducing errors and improving reliability.

  • Statement II – Incorrect
    The Majorana 1 chip was not introduced by Amazon Web Services (AWS). It is associated with Microsoft’s quantum computing research, particularly its work on topological qubits. AWS focuses on cloud-based quantum computing platforms (like Amazon Braket), not on developing Majorana chips.

  • Statement III – Correct
    Deep learning is a subset of machine learning, which itself is a subset of artificial intelligence (AI). Deep learning uses neural networks with multiple layers to process complex data such as images, speech, and text.

Answer: (c) I and III only
