Avoiding unexpected observations

[sweet springs]

Hello. Preventing unexpected observations to take place during the process of quantum computing should be a necessary technology. May I have general ideas how the tech people are taking care of this issue ?

At work, we joke about putting "do not look directly at quantum computer" stickers on the dilution refrigerators. The main reason not to is that one day some poor reporter might take it seriously.

You protect quantum information from leaking into the environment with quantum error correcting codes. For way more details, see the paper Surface codes: Towards practical large-scale quantum computation.
