A quantum optics researcher in Austria is testing entangled photon transmission across three nodes in a quantum network. If Node A sends 120 photons per second, Node B reflects 75% of incoming photons and replies with entangled pairs at a rate of 80% of received photons, and Node C forwards 60% of the reflected entangled pairs to Node A, how many entangled pairs reach Node A every minute? - Veritas Home Health
