While it is normal for occasional slight rubbing of brakes pads, if the pads did not rub before you removed a wheel, they should not rub after putting it back.
Make sure the wheel axles are completely seated in the dropouts and that the quick releases are tightened correctly.
Also, do not pull a brake lever while the wheel is off or you will have to pry the brake pads apart.
