Room A4 (1) "Back Seat"

Just one receiver in this room, but the arrows don't look like they'll guide a particle to it.

Look for a way to guide it indirectly.

You'll find the arrows are the opposites of those needed to guide a particle to the receiver directly.

Can you use entanglement?

Split the particle, then use arrows on one particle to steer the other towards the receiver.

Specifically, split it left and right, then guide the right-hand particle down and then left so that the other goes up and then right.
