Let us assume that a photon propagate in z direction.
For the z direction size, we can make it as small as possible (at least theoretically) by superpositioning a various wavelength photon states, which becomes a delta function in position space while it's just a plane wave in momentum space...
Hello, I'm reading a book "How to teach quantum physics to your dog" from Chad Orzel, which is of great fun. Recently I become interested in quanntum Zeno effect. I can't understand why we can't see the quantum Zeno effect in daily life.
Below is what I posted on my facebook, and my friend's...
