AFAIK, the rules of quantum mechanics are rather silent upon the 'length'
of a photon.

Last time I looked, the emission and absorbtion process was considered to
be practically 'instantanious', with the half life of the excited state
being the parameter under study.

The paper
http://jchemed.chem.wisc.edu/JCEWWW/Articles/DynaPub/DynaPub.html#ref16
seems to confuse the half life of the excited state with the time required
to actually emit a photon and to equate that with the photon length.

Did someone say the *sample* size was one ?

Santa can deliver 2.3 toys to *ONE* house
with a high degree of certainty that each
child in the house will get a toy.

Only if Santa restricts his deliveries to a small portion of the globe.

BZ: Only if Santa restricts his deliveries to a small portion of the
globe.
<< I see no reason for a single photon to be longer than one cycle.>>

Sue: Well maybe it has to be at least four cycles in case
some astromnomer wants to cut it into four pieces.

GAWD! you don't suppose Santa elves cut up the toys do you?

Naw, they just need for 4 photons to arrive from the same source at the
same time.

> GAWD! you don't suppose Santa elves cut up the toys do you?

Naw, they just stretch them out over millions of cycles.
