Hi everyone,
When calling 'groundState' on an identity matrix, I'm getting a 0 ground state energy (instead of 1). I was wondering if anyone else has faced a similar issue?
In general, are we allowed to modify the actual modules or not?
No, you are not supposed to modify the modules. The algorithm used by the groundState function does not work if all eigenvalues are equal. It is okay that you have a test that fails. It means the test is doing what it is supposed to; find bugs.
Thank you very much for the clarification.
