Topic Quantum Computing
Asked 3 times across 2 UPSC exams over 4 years (2022–2026), peaking in 2022.
Key insights
- Most tested in CSE — 2 of 3 PYQs
- Most asked in 2022
- Recurs across 3 years (2022–2026)
How it travelled across exams
First appearance in each exam — the same idea, reframed.
CSE 2022 → ESE 2026
How the concept evolved
Rising — more than half its appearances (3 of 3) are since 2016.
Sample questions
You've seen the pattern — here are a few of the actual PYQs.
ESE2026
Consider the following statements regarding quantum dots
- A photon's polarization can be vertical or horizontal, or a superposition of both, and we can use this as a qubit
- Neutral atoms can be trapped at low temperatures using a magneto optical trap, which uses magnetic fields and lasers to cool and trap the atoms
- An electron can be bound to a small semiconductor device, similar to an electron bound to the nucleus of an atom. In these "artificial atoms", the spin of an electron, which can be "spin up" or "spin down", can be used as a qubit
Which of the above statements is/are correct ?
- A 1 only
- B 2 only
- C 3 only
- D 1, 2 and 3
