Which of the following statements about quantum computing are correct? Choose the correct answer from the options given below.
- 1. Principles of quantum physics are applied in it
- 2. Quantum bits (qubits) are used as the information unit
- 3. Quantum computers emit radiation fatal to humans or users
A1 and 2 only ✓ Correct
B1 and 3 only
C2 and 3 only
D1, 2 and 3 only
Correct answer: (A) 1 and 2 only — Quantum computing uses quantum physics and qubits, so the answer is 1 and 2.
Explanation
★Quantum computing uses quantum physics and qubits, so the answer is 1 and 2.
★Quantum computing solves complex problems by using the rules of quantum mechanics.
★It applies principles of quantum physics such as superposition and entanglement.
★Its basic unit of information is the quantum bit, or qubit.
★A qubit can represent more states than a classical bit.
★Quantum computers do not emit radiation fatal to users, so statement 3 is false.
