Does Quantum Physics End the Free Will Debate?

Michio Kaku, a theoretical physicist at C.U.N.Y., explains why he thinks quantum physics affects the debate about free will and determinism.

One of the problems I have with such physics-based explanations is that they do not address how the human will relates to physical matter. Without addressing that connection, the theory only touches on the question if we assume that the human will is reducible to matter (e.g., the brain). What do you think? How useful are such explanations?
