California Community Property with spouse in different state

Hello - If I am CA resident and my spouse is a Georgia resident and we are filing married filing jointly for federal and state, how does community property work? Do I have to take and show 50% of spouse's pro-rate income which is just salary, even though they are non-resident of CA? If so, do I claim the tax deduction in CA return or should they claim the credit in GA return for taxes paid in CA? Thanks!
