    Hi, first time here at this forum. I wanted to know if it is possible to continue entanglement after the first measurement. I know conventionally this isn't possible because the measurement changes the state of one particle, but what if both particles were measured with photons of the exat same energy, which hit particles at the exact same time? Additionally, what if along with the measurement, the spin of the particles was changed using the Zeeman effect. Would this continue the entanglement? Because at this point, the spin is in superposition again.

    I don't think that two entangled particles can interact with two photons simultaneously. According uncertainty principle, if you choose certain instant, then you can't determine energy of the particles.
