public interface TranspilerPass
A transpiler pass that transforms a quantum circuit.

Transpiler passes can perform optimizations, gate decompositions, qubit mapping, and other transformations on quantum circuits to adapt them for specific hardware or improve performance. Each pass takes an input QuantumCircuit and produces a new transformed QuantumCircuit.
