Regarding decoherence_and_amp_decay

What is the current behavior?

In dm_simulator.py
The amplitude decay ,thermalization and decoherence is applied at end of every clock cycle to all the qubits.
In the main code at line 1173 a for loop is applied for adding errors to all the qubits by calling _add_decoherence_and_amp_decay function .
Inside the function _add_decoherence_and_amp_decay again a for loop is applied for all the qubits at line 411.
I think one of the loop is redundant but not sure .
Request your comments on the same

@gitkarma Thanks for pointing it out. It seems like there have been a mistake. I will look into it carefully, maybe discuss with the other developers and fix this issue soon.
