Qubits in Quantum Computing: MCQ Solved with Detailed Explanation

The term “qubits” primarily associates with quantum computers, making option b. Quantum computers the correct answer in this multiple-choice question.

Option Analysis

a. Black holes: Qubits appear in advanced theoretical physics linking quantum information to black hole entropy via string theory and holography, such as qubit entanglement modeling Hawking radiation. However, this remains a niche research area, not the standard association.​

b. Quantum computers: Qubits are the fundamental units of quantum information, analogous to classical bits but capable of superposition and entanglement for exponential computational power. This direct connection defines their primary usage.​

c. Whole genome sequencing: This process relies on classical DNA sequencing technologies like NGS, with no involvement of qubits, which pertain to quantum mechanics rather than biological data analysis.

d. Sea level rise: Climate models for sea level rise use classical supercomputers for simulations; qubits play no role in environmental or geophysical predictions.

Qubits quantum computers form the core of next-generation tech, powering solutions beyond classical limits. This qubits quantum computers MCQ explanation breaks down why “quantum computers” is the key association, ideal for CSIR NET Life Sciences and tech aspirants exploring interdisciplinary quantum biology.

Why Qubits Define Quantum Computers

Qubits enable quantum computers to process vast possibilities simultaneously through superposition, unlike binary bits. Companies like IBM and Google build prototypes with 50+ qubits for drug discovery and optimization. In exams, this direct link trumps indirect physics ties.​

Ruling Out Other Options

• Black holes: Theoretical models use qubits to probe information paradoxes, but qubits originated in quantum computing, not astrophysics.​

• Whole genome sequencing: Classical algorithms handle DNA data; quantum could accelerate, but qubits aren’t associated yet.

• Sea level rise: Purely classical climate modeling—no quantum elements.

Exam Prep Tips for Qubits Questions

• Focus on qubits as quantum bits for superposition/entanglement.

• Link to biotech applications like protein folding.

• Practice similar MCQs: Qubits appear in emerging quantum biotech for CSIR NET.
