There is no doubt about it whatsoever. The massive destruction was the result of a single nuclear air burst, from a weapon dropped from a single B29 bomber.
Both US and Japanese military records confirm that a single bomb was dropped from a very small flight group (three B-29 bombers in total: Enola Gay, which dropped the bomb; The Great Artiste, which carried instrumentation to observe the effects of the bomb, and a then-unnamed Photography plane).
