Show answer
Answer: (C) I and III only
Let's evaluate each statement:
(I) 'Majorana 1 chip will enable quantum computing' — CORRECT.
The Majorana 1 chip is based on a new type of qubit called a 'topological qubit,' which uses Majorana particles.
These qubits are expected to be much more stable and less error-prone than existing qubits, potentially making practical quantum computing feasible. ✓
(II) 'Majorana 1 chip has been introduced by Amazon Web Services (AWS)' — INCORRECT.
The Majorana 1 chip was introduced by Microsoft, not AWS.
Microsoft announced this chip in February 2025 as a breakthrough in topological quantum computing.
AWS has its own quantum computing efforts (like Amazon Braket), but the Majorana 1 is specifically a Microsoft product. ✗
(III) 'Deep learning is a subset of machine learning' — CORRECT.
This is a fundamental concept in AI:
- Artificial Intelligence (AI) is the broadest category
- Machine Learning (ML) is a subset of AI
- Deep Learning (DL) is a subset of ML.
Deep learning uses multi-layered neural networks and is a specialized technique within the broader field of machine learning. ✓
Statements I and III are correct. Answer is (c).
Microsoft announced the Majorana 1 chip in February 2025 as a breakthrough in topological quantum computing using Majorana particles for more stable qubits.
UPSC is testing whether students can distinguish between major tech companies' quantum computing initiatives - Microsoft's topological qubits versus AWS's Braket platform.
The question mixes cutting-edge quantum hardware developments with basic AI hierarchy concepts to test both current awareness and fundamental knowledge.
Majorana 1 Chip & Topological Qubits
Science And Technology Majorana 1 chip quantum computing topological qubit
Majorana 1 Chip: Microsoft's Topological Quantum Computing Breakthrough
Majorana 1 chip developed by Microsoft (not AWS) - announced February 2025
Uses topological qubits based on Majorana particles for quantum computing
Topological qubits are more stable and less error-prone than conventional qubits
Represents breakthrough in making practical quantum computing feasible
What Makes It Special
The Majorana 1 chip represents a fundamental shift from conventional quantum computing approaches. Instead of using traditional qubits that are highly sensitive to environmental interference, it employs topological qubits based on Majorana particles - exotic quantum states that are naturally protected from errors.
Conventional vs Topological Qubits
Aspect | Conventional Qubits | Topological Qubits (Majorana 1) |
|---|---|---|
Error Rate | High - sensitive to noise | Much lower - naturally protected |
Stability | Require complex error correction | Inherently stable due to topology |
Development Company | IBM, Google, others | Microsoft |
Commercial Viability | Still challenging | More promising for practical use |
Quantum State | Fragile superposition | Topologically protected |
Why This Matters
Error correction has been the biggest barrier to practical quantum computing
Most quantum computers today can only run for microseconds before errors accumulate
Topological protection could enable hours or days of stable quantum computation
Microsoft's approach differs from competitors like IBM and Google who use superconducting qubits
Trap: Statement II incorrectly attributes Majorana 1 to AWS - it's actually Microsoft's product
Don't confuse with Amazon Braket (AWS's quantum cloud service) or IBM Quantum
Majorana particles ≠ regular particles - they are their own antiparticles
AI, Machine Learning & Deep Learning Hierarchy
Science And Technology Deep learning machine learning subset
AI → Machine Learning → Deep Learning: The Complete Hierarchy
Deep Learning is a subset of Machine Learning, which is a subset of AI
AI = broadest field; ML = learning from data; DL = multi-layered neural networks
Each level becomes more specialized and narrow in scope
AI Technology Hierarchy
# Artificial Intelligence

- Unsupervised Learning
- Reinforcement Learning
## Expert Systems
- Rule-based
- Knowledge bases
## Natural Language Processing

- Language translation
## Computer Vision

- Object detectionKey Differences
Level | Definition | Examples | Data Requirement |
|---|---|---|---|
Artificial Intelligence | Machines performing tasks requiring human intelligence | Chatbots, Chess programs, Siri | Varies |
Machine Learning | Algorithms that learn from data without explicit programming | Email spam filters, Recommendation systems | Large datasets |
Deep Learning | Multi-layered neural networks mimicking brain structure | Image recognition, Speech synthesis, GPT | Massive datasets |
Deep Learning Specifics
Uses artificial neural networks with 3+ hidden layers (hence 'deep')
Excels at pattern recognition in images, speech, and text
Requires massive computational power and training data
Powers modern breakthroughs like ChatGPT, image generation, and autonomous vehicles
Never reverse the hierarchy: ML is NOT a subset of DL - it's the opposite
AI ≠ ML: AI includes non-learning systems like rule-based expert systems
Don't confuse Deep Learning with Machine Learning - DL specifically uses neural networks

Company Specializations
AWS strategy: Provide cloud access to quantum computers from multiple vendors, not build own hardware
Microsoft's bet: Topological approach is riskier but potentially more stable than competitors
IBM leadership: Most extensive quantum computer network with 1000+ qubit systems
Google achievement: First to demonstrate quantum supremacy with specific computational task
AWS does NOT manufacture quantum chips - they provide cloud access via Amazon Braket
Don't confuse Microsoft Azure (cloud) with Microsoft Quantum (hardware research)
Quantum supremacy ≠ practical quantum computing - Google's 2019 achievement was for specific task only
