Measurement of gravitation is quite inaccurate, ...You're referring only to the gravitational attraction of small objects. However it's extremely easy to measure the gravitational attraction between me and the earth. My doctor asks me to do it everytime I visit his office.

..so any quantum fluctuations would be very hard to measure. It is said that the gravitational constant G is the least accurately known fundamental constant.It's not clear whether he's refering to the uncertainty principle applied to the field itself or particles moving in the field. I'm not even sure that there's an uncertainty principle for the fields themselves. Are you?
