Bug: Measurement on subset of qubits

[YunJ1e]

Bug Description:
Measuring only a subset of the quantum circuit will return errors.

Code to Reproduce the Bug:
The code is from the documentation website.

import numpy as np
from quafu import QuantumCircuit, Task
q = QuantumCircuit(3)
q.x(2)
q.delay(2, t, unit="us")
q.measure([2])
task = Task()
task.config(backend="ScQ-P18", shots=2000, compile=False)
res = task.send(q)

Code Output:

IndexError: string index out of range

My Debugging Trials:
And if you change the one line of code q.measure([2]) to q.measure([0, 1, 2]) will simply solve the problem. But it would be better if your team could come up with proper solutions that could either prevent users from measuring subsets of qubits or support this feature.

Thanks, looked into this issue

We do support this

Partial measurement a supported feature, we are fixing this issue and will release assp, see the pr

Now you can build from stable/0.3

git checkout -b stable/0.3 origin/stable/0.3
python setup.py install

We will release new version to pypi later, closed
