Hello people, prepare for the long post
Just a bit of context:
I’m a software developer and during last year a lot news about quantum computing showed up and I spent a lot researching it on my own out of curiosity, So I’m aware I can make wrong assumptions and/or not understand, what some of you may consider basic in the subject. My grammar may fail too, as I’m not a English native speaker. For case of any, I’m sorry beforehand;
Let’s talk about the more common experiment they first show us, the double slit experiment. Considering that small enough particles change their behaviour as we observe it or not; they are in superposition until we interact, in some way affecting even the past.
(Kinda off-topic: First thing I cannot reach at any conclusion is if computers count as observers, classical ones probably do as they can only assume one state or the other, but in the other hand there’s no ‘person’ watching until it shows up on the screen a result, right?
I can’t answer that myself.)
Now let’s say I have a quantum computer (I assume this one can keep the result and keep it without interference until I try to see it).
Now let’s say we do have a quantum computer and it work as I image it, and that I’m able to make a game in it…
I have a sensor that perform the double slit test (using photons, maybe), the output of it will all be a secret, no one will ever see it if we do ask it to do so. The hidden output are two:
- if either acted as a particle or wave
- which slit was used by the photon
Using the assumption that everything will be in superposition if nobody tries to watch the results now follow this algorithm:
1: Execute the slit test, keep the result from the user;
2: If the output was a wave let’s show a Square
3: Else I show a triangle
4: Wait some time and show a two-option choices, Yes or No
5: If Yes was choosen, I show where the particle passed by, using the second output
6: Else, we destroy any evidence we had about which way the particle went, nobody will ever know;
Now, how will this work? Would the user see different results depending on his later action? I know I’m breaking the rule of causality here, but I cannot reach to an outcome having the knowledge I have right now.
Does anyone clear this to me?
