The point of this thought experiment has been widely taken out of context and misused by new age science supporters. Schrodinger initially considered this experiment to show the RIDICULOUSNESS of the situation, not because it was physically what is happening. Additionally, anyone who says that there is a line between the quantum and classical regime is ...

Is the probability $|c_1|^2 + \ldots + |c_k|^2$? Yes or no. It happens $\frac{|c_1|^2 + \ldots + |c_k|^2}{|c_1|^2 + \ldots + |c_N|^2}$ fraction of the time in the long run. (Assuming the states you listed were all normalized.) What state does the system jump into after this measurement? There is no experimental evidence of jumps or anything discontinuous. ...

As an experimental physicist, I go back to basics: Here is a double slit experiment a single photon at a time: The top panel shows dots from single photons coming in at the slits. The others the slow accumulation by which an interference pattern appears. That is what the experiment shows, dots like one would expect from single particles, ...

As in John Rennie's answer we cannot describe the photon as being in a superposition of "going through different slits" states. But there is a sense wherein the answer to your question "Is a photon always in a state of superposition while traveling through space?" is almost always "yes". And the answer depends on a choice of co-ordinates. To answer the ...

It basically boils down to this. Looking at a flying electron through a camera, there is no interference. Nothing special. But not trying to find which slit it went through and gradually observing the electrons to hit the detector there is interference pattern. In other words, when trying to find which slit the electron went through, wave function collapses ...

Things are amazing for as long as you do not (or refuse to) understand them! What happens is that, counterintuitively, everything around us is waves (matter or de Broglie waves). Hence they naturally interfere, producing for example the diffraction patterns behind a double slit (or indeed even a single slit). Waves naturally and unsurprisingly obey the ...

If we take two slits large enough for bowling balls and with a much smaller than the ball separation , and a pile of bowling balls and design a catapult throwing the balls at the slits parallel to the ground within the window covering the two slits, what will happen? 1) some balls will pass through one of the slits without touching, straight ahead 2)some ...
