The index of the instruction in the original circuit's instruction list.
The time step (column) in the circuit diagram where the gate is placed.
An array of target indices that this gate acts upon.
The display name of the gate (e.g., "H", "CX").
Optional
parametersOptional parameters for parameterized gates (e.g., rotation angles).
Optional
isFor multi-qubit gates, indicates which targets are control qubits.
Describes the position and properties of a single gate within a circuit layout.
