Bug report: ConditionEnvironment in python 3.12 #55

Closed renezander90 closed 2 months ago

renezander90 commented 3 months ago

The following code, when executed in a python environment with python=3.12 and the Qrisp version from the main branch on GitHub,

from qrisp import QuantumChar, QuantumFloat, h, multi_measurement

q_ch = QuantumChar()
qf = QuantumFloat(3, signed = True)

h(q_ch[0])

with q_ch == "a":
    qf += 2

produces a bug:

AttributeError: 'NoneType' object has no attribute 'deallocated_qubits'

A similar bug occurs for the ControlEnvironment in this setting.
