I'm trying to understand the time delay induced on each photon when several individual photons travel in an open space from a sender to a receiver for example in the application of Quantum Key Distribution. So what I understand so far is light(photon) travel around 299,792 km (186,282 miles) per second. If I were to send 5 individual photons over to the other side from sender to receiver through an open space using a laser, let's say 50 km (31.0686 miles), it would take 0.167 ms to reach the receiver.
Therefore, I want to know if it is TRUE for every individual photon (that it will take 0.167 ms to reach receiver) or will there be slight variation on the time delay for every individual photon? With that said, can time delay be calculated that precisely when calculating the time taken for a photon to travel from one sender to another (receiver): Assuming time stamp are attached to each photon when sent and another time stamp are attached once received.
Feel free to correct me if my facts/calculations are wrong.
