Previous Year Question
Consider the following statements.
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?
I and II only
II and III only
I and III only
I, II and III
Correct Answer: C
Detailed Solution
Statement I is correct. Majorana 1 is a quantum computing chip designed to advance the development of more stable and scalable quantum computers. In a classical computer, the fundamental unit of information is a bit, which has a value of either 0 or 1; whereas in a quantum computer, a qubit can exist in a combined state of 0 and 1 due to superposition.
Majorana 1 uses a Topological Core architecture and a material platform described by Microsoft as a topoconductor. The objective of developing topological qubits is to reduce quantum errors caused by environmental noise and to scale quantum systems to larger sizes. This technology is still developing, but it is expected to enable more capable quantum computers for solving complex scientific problems.
Statement II is incorrect. Majorana 1 was introduced not by Amazon Web Services but by Microsoft. AWS has its own quantum computing service—Amazon Braket—but it is not the developer of the Majorana 1 chip.
Statement III is correct. Deep learning is a specialised subset of machine learning. It uses artificial neural networks containing multiple computational layers to learn complex patterns and features from data. Image recognition, speech processing, natural language processing and autonomous systems are among its major applications.
