The wave function's collapse is just an observer suddenly and discontinuously revising his or her probability assignments based on new information, in the same way that a doctor would revise a ...

If the wave function is a real object, then one of those possibilities always has a zero probability, because the wave function is either representing the good state or the bad state, but not both.

One example is a wave in shallow water. Though governed by classical hydrodynamics, shallow water waves can have waveforms ...

In the quantum world, things hover in a fuzzy, nebulous cloud of probability called a wave function that encompasses all potential states, with no prospect of gaining further information.

But problems arise when physicists assume that a wave function is real. QBism, which combines quantum theory with probability theory, maintains that the wave function has no objective reality.

The wave function—and hence the probability of finding a nuclei—goes to zero in a periodic fashion, so there are some places that a nuclei should never be found.

But Born argued instead that the amplitude of the wave function is related to a probability — specifically, the probability that you will find the particle at that position if you detect it ...

There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, ...

To describe the huge numbers of positions and velocities a particle can have at any given moment, physicists use wave functions, which are essentially probability equations.
