# qiskit.pulse.builder.measure_all¶

measure_all()[source]

Measure all qubits within the currently active builder context.

A simple macro function to measure all of the qubits in the device at the same time. This is useful for handling device meas_map and single measurement constraints.

Examples:

from qiskit import pulse
from qiskit.test.mock import FakeOpenPulse2Q

backend = FakeOpenPulse2Q()

with pulse.build(backend) as pulse_prog:
# Measure all qubits and return associated registers.
regs = pulse.measure_all()


Note

Requires the active builder context to have a backend set.

Return type

List[MemorySlot]

Returns

The registers the qubit measurement results will be stored in.
