shiavm006 opened a new issue, #603:
URL: https://github.com/apache/mahout/issues/603
### Description
The `bind_parameters` method silently ignores parameter names that don't
exist in the circuit. When users pass incorrect parameter names (typos, wrong
names, etc.), no error is raised. This causes the parameter to remain unbound
(`None`), leading to cryptic errors later during circuit execution deep in
backend code.
### Steps to Reproduce
1. Create a parameterized quantum circuit and add a parameterized gate
2. Call `execute_circuit()` with an incorrect parameter name (typo or wrong
name)
3. Observe that no error is raised during parameter binding
4. Circuit execution fails with cryptic error message
**Example code:**
```python
from qumat import QuMat
config = {
"backend_name": "qiskit",
"backend_options": {"simulator_type": "aer_simulator", "shots": 1024}
}
qumat = QuMat(config)
qumat.create_empty_circuit(1)
qumat.apply_rx_gate(0, "theta")
# Execute with TYPO: "thta" instead of "theta"
result = qumat.execute_circuit({"thta": 3.14})
```
### Expected Behavior
Should raise an immediate, clear error message:
