Discussion of the Bose-Einstein condensate got me to wondering about the implications of a quantum entity with a very precise position.

Can a quantum entity be constrained to have a very precise position? If so, how?

What would be the implications/effects due to the precise position?

Hi Dinosaur,

What do you mean by constraining to a very precise position ? And on what scale are we talking here. One fundamental particle can be constrained quite accurately on a nanoscale (e.g. think of electron traps), but if you want to trap it even more precise (e.g. 1000 times more precise) then quantum uncertainty effects could come into play. It depends on the required precision I guess.

Macroscopic objects such as BEC can "easily" be constrained using electromagnetic fields or such.

Bye!
