What is a quantum circuit?
a) A classical circuit with quantum gates
b) A sequence of quantum gates that perform a computation on qubits
c) A tool for simulating quantum computers
d) A physical device for measuring qubits
Answer:
b) A sequence of quantum gates that perform a computation on qubits
Explanation:
A quantum circuit consists of quantum gates applied in sequence to qubits to perform computations, similar to logic circuits in classical computing.
