Quirrell heard about Minerva’s decision to support more heroism. He realized that Harry changed his original plan (to make all teachers obstacles to Harry, except Quirrell himself), but adapted quickly. He asked Minerva to do something heroic together, as teachers—to travel to the past and try saving Hermione.
In the past, he changed Minerva to Hermione, telling her that now the attack will come to Minerva and she can better defend against it, or do something very clever. Without Minerva’s knowledge, he changed Hermione into a troll, and somehow made her believe that the enemy’s plan is the following: while the real Hermione cannot be found, the false Hermione will try to kill Harry. Or something like that.
Now the troll (Hermione) heroically followed and attacked the false Hermione (Minerva) and tried to kill her. The sun didn’t hurt the troll, because it was not a real troll. Harry came and killed the troll (Hermione), which made the wards report that a student was killed. The dying false Hermione (Minerva) tried to do the right thing and explain Harry that it was not his fault.
Quirrell is now waiting for the moment when Harry tries to revive Hermione and realizes that the body/brain that he saved actually belongs to Minerva from the future. Then Harry will realize that he killed Hermione, and specifically destroyed her brain by explosion. That should turn Harry to the dark side.
In the Star Wars universe, maybe, where being betrayed by somebody automatically makes you join them (as does, reportedly, killing them). But Harry is more rational than Anakin.
Actually, it was all like this:

Problems:
1 - The troll regenerated.
2 - The troll was identified as a professor, not as a student.
Plus, if troll-Hermione wanted to kill a fake-Hermione I doubt she would start by eating her legs.
