Leaving work after maternity leave / congé parental

Hi everyone, my question is, if I am quitting work after my congé parental (which followed the maternity leave), do I need to go back for 6 weeks while the notice period runs, or can it run alongside my "congé"? Also, if I resign, would i be entitled to chomage? I thought one only got it if the company had made you redundant, but not by quitting.
Thanks a lot!!
