I've had an idea I would like feed-back.

Let's imagine a particle on an x axis. On it's initial state it is localized in segment [0,1] as a purely symmetric wave.

The quantum Zeno effects tells us that if we measure wether the particle is still in [0,1]

**times during one second, the probability that we find the particle outside of [0,1] tends to 0 when**

*n***tends to infinity.**

*n*Now suppose that during 1 second we measure

**times wether the particle is in [-0.5,1] and then we do a final measurement to know wether it is in [-0.5,0.5].**

*n*When

**tends to infinity the probability that we find the particle outside of [-0.5,1] tends to 0, but during the second of intensive measurements the wave still spreads normally to [-0.5,0]. Therefore the probability that the particle is found in [-0.5,0] is strictly greater than 0, and the probability that it is found in [-0.5,0.5] is obviously strictly greater that 0.5.**

*n*Therefore by this rather simple (and improvable) measurement scheme, we seem to be able to influence the direction the particles goes towards, and not only freeze it.

What do you think? Is that right or do I make a logical mistake? Or is that an already know effect?

Thank's in advance!

Pierre.
