You are very confused.
zero point energy is the energy that remains at 0 temperature, or absolute zero.
There is nothing in physics that says a Temperature of absolute zero cannot be reached.
This is so stupid, and I don't know how many times you go around giving people this false knowledge. Zero temperature refers to a zero Kelvin state, it is well-known and well-written about that no system actually exists at a zero temperature, instead, a correction is given into the equations because you cannot create a perfect vacuum.
There is no state at zero temperatures, all that exists is the ground state, known as the zero point field which contributes a true ground temperature to the vacuum.
