What is the quantum observer effect?
Content: This “collapse” from many possible values to a single possible value (the measured value) can lead to a dramatic change in the subsequent dynamics of the system. An interesting consequence of the quantum observer effect is the Quantum Zeno effect. By observing a system often enough, you can slow or effectively stop is evolution. For example, suppose that you measure the position of an electron at some point in time. Quantum dynamics dictates that after that measurement it will fly off in a random direction from that position with a random speed and be found somewhere else a moment later. However, if you continuously monitor its position (or make a very rapid succession of measurements), the electron will stay in that one place for as long as the measurements go on. Malcolm Shute
