Conclusion
As a result of calculation, V-type atoms have quantum beats but -type atoms do not. This difference is caused by quantum mechanical uncertainty. A V-type atom decays to state via the emission with and . Since both transitions decayed to the same state, one cannot determine along which path each decayed, similar to Young's double-slit experiment. However, -type atoms decay to two different states. Therefore, in this case we can recognize the path, even if it decays via two emissions as does V-type. Simply, we already know the path of the emission and decay.
The calculation by QED is correct in accordance with the most fundamental principle of quantum mechanics, the uncertainty principle. Quantum beats phenomena are good examples of such that can be described by QED but not by SCT.

Famous quotes containing the word conclusion:
“It is a great many years since at the outset of my career I had to think seriously what life had to offer that was worth having. I came to the conclusion that the chief good for me was freedom to learn, think, and say what I pleased, when I pleased. I have acted on that conviction... and though strongly, and perhaps wisely, warned that I should probably come to grief, I am entirely satisfied with the results of the line of action I have adopted.”
—Thomas Henry Huxley (1825–95)
“of making many books there is no end; and much study is a weariness
of the flesh.
Let us hear the conclusion of the whole matter: Fear God, and keep
his commandments: for this is the whole duty of man.”
—Bible: Hebrew Ecclesiastes (l. XII, 13)
“The source of our actions resides in an unconscious propensity to regard ourselves as the center, the cause, and the conclusion of time. Our reflexes and our pride transform into a planet the parcel of flesh and consciousness we are.”
—E.M. Cioran (b. 1911)
