1. The Circuit Model: Reading Scores

The Circuit Model

Quantum computing has a standard notation called the Circuit Model.

Look at the simulator below. It looks like a musical score, right?

• Time: Moves from left to right.
• Qubits: Horizontal lines (like strings on a guitar).
• Gates: Boxes or symbols placed on the lines. These are operations happening at specific times.

The Takeaway: We compose quantum algorithms like music, sequencing operations in time to manipulate the state of the qubits.
