The qubits are measured in the computational basis.

Args
*target	The qubits that the measurement gate should measure.
key	The string key of the measurement. If this is None, it defaults to a comma-separated list of the target qubits' str values.
invert_mask	A list of Truthy or Falsey values indicating whether the corresponding qubits should be flipped. None indicates no inverting should be done.

Returns
An operation targeting the given qubits with a measurement.

Raises
ValueError if the qubits are not instances of Qid.
