This quantum circuit initializes a system qubit and performs two measurement interactions at different times, recording the outcomes.
```python
from qiskit import *
# Create a circuit with 3 qubits and 2 classical bits
qc = QuantumCircuit(3, 2)
# Initialize the system qubit in the |+⟩ state
qc.h(0)
# First measurement interaction at time t1
qc.h(0)
qc.cx(0, 1)
qc.h(0)
# Second measurement interaction at time t2
qc.h(0)
qc.cx(0, 2)
qc.h(0)
# Measure the ancilla qubits to record the outcomes
qc.measure(1, 0)
qc.measure(2, 1)
```
