Noisy Simulation
-----------------

CUDA Quantum makes it simple to model noise within the simulation of your quantum program.
Let's take a look at the various built-in noise models we support, before concluding with a brief example of a custom noise model constructed from user-defined Kraus Operators.

The following code illustrates how to run a simulation with depolarization noise.

.. tab:: C++

   .. literalinclude:: ../../examples/cpp/basics/noise_depolarization.cpp
      :language: cpp

The following code illustrates how to run a simulation with amplitude damping noise.
