Quantum Circuit

A quantum circuit is a model used to perform quantum computations, similar to how a classical circuit processes information. It consists of quantum bits (qubits) and quantum gates that manipulate their states through principles like superposition and entanglement. These gates are like specialized operations that change the probabilities of a qubit's state, enabling complex calculations that can solve certain problems more efficiently than traditional computers. The circuit’s design guides how qubits are prepared, transformed, and measured, ultimately producing outputs that reveal solutions based on quantum phenomena.
