18. The desired processes are thus postselected, leading to a decrease of count rates. It is in principle possible to create only the events in the central peaks using switches instead of passive couplers [14].

23. Note that it is only important that the obtained data violates the Bell inequality and that this criterion applies even to crypto systems based on single photons. Nonlocality is not an issue in this context [17]!
