From the article:

"But if your only tool is a hammer, 
then you tend to treat everything 
as if it were a nail," says Tollaksen. 
"The problem was that the 'hammer-type' 
measurements usually are not the most 
useful in figuring out how the quantum 
world links the future with the present 
in subtle and significant ways."

Aharonov and his team have worked for 
two decades on new types of gentle 
"weak measurements," which can see 
these linkages--"akin to tapping something 
softly with your finger rather than 
smashing it with that hammer, which 
forces each pigeon to be in a single box," 
Tollaksen says.

From the abstract:

"We find instances when three quantum 
particles are put in two boxes, yet no 
two particles are in the same box."

The article says there is a supporting 
experiment, the abstract only suggests 
an experimental course, says to refer to 
Phys. Rev. A, if you happen to have that handy.



Wondering that they've figured out a way, 
to, look at each box, and it's always 
the other one, like "Monty Haul".  After 
all, all the particles are in all the boxes.

"Furthermore, both the preparation 
and the postselection are done 
independently, acting on each particle 
separately. "

Uh, what's in the other box.
