Undefined Quantum Gates -X, H, MZ when running CUDA-Q Docker in VS Code

[srinjoyganguly]

Hello everyone,

I am trying to run the Bernstein Vazirani algorithm using VS Code by running the latest CUDA-Q Docker image, but the file shows that the Quantum Gates - X, H and MZ are undefined. I am using Windows for the work.

Can you please help me figure out the problem?

When I run the code, it shows a random output of a quantum circuit having six qubits. When I change the number of qubits, the output does not change and is not according to the number of qubits I gave. Here is the screenshot -

For Pylance error(s), can you try adding from cudaq.qis import * after the import cudaq statement?

The example you are trying doesn't take input argument size
Ref: https://github.com/NVIDIA/cuda-quantum/blob/main/docs/sphinx/examples/python/bernstein_vazirani.py

Try changing qubit_count in the file.
