qiskit.circuit.QuantumCircuit.depth

QuantumCircuit.depth(filter_function=<function QuantumCircuit.<lambda>>)

Return circuit depth (i.e., length of critical path).

Paramètres

filter_function (callable) – A function to filter instructions. Should take as input a tuple of (Instruction, list(Qubit), list(Clbit)). Instructions for which the function returns False are ignored in the computation of the circuit depth. By default filters out « directives », such as barrier or snapshot.

Renvoie

Depth of circuit.

Type renvoyé

int

Notes

The circuit depth and the DAG depth need not be the same.
