Hello everyone. I'm only just starting to look into degree programs for physics, so this question may not be worded well, or make much sense. Hopefully it does.
According to a couple of books I've read, you could theoretically search a large database for specific entries in a quantum computer using Grover's Algorithm. This involves using laser pulses to find the correct entry, inverting it's wavelets, and then inverting the system about the average until the correct entry's amplitude is high enough for the system to collapse from superposition into it with high accuracy.
It's my understanding that if an atom in superposition is measured or observed in any way, the superposition will collapse immediately. My question is, how is it possible to search for the correct entry using laser pulses without causing to superposition to collapse?
