In quantum mechanics, wave function collapse occurs when a wave functioninitially in a superposition of several eigenstatesreduces to a single eigenstate due to interaction with the external world. I do want to know what happens with the other possible states, whether they stay alive but in another form, or what's Collapse is one of the two processes by which quantum systems evolve in time; t How does a wave function collapse when I measure position? Wave function collapse is a figure of speech, not a physical process. So there is no how. If you measure a position somewhere, that means that the position isnt also going to be measured elsewhere. 2 : to break down completely : disintegrate his case had collapsed in a When the atom interacts with an object (is measured), the wave function collapses. Upon collapse, the atom is measured as having one of the two possible energy levels. In this animation, the collapse of the wave function is called decoherence. More about decoherence in a later section of this article. Collapse of the Wave Function The collapse of the wave function is also known as the reduction of the wave packet.. This describes the change from a system that can be seen as having many possible quantum states (Diracs principle of superposition) to its randomly being found in only one of those possible states. Although the collapse is historically thought It's pity that none of the answers (though great ones have been given!) mentions an interpretation of quantum mechanics which assumes a physical re I believe the answer is yes, because its exact speed cannot be proven experimentally, but I would like to know a little bit more. The collapse of the wave function, as first emphasized by Werner Heisenberg and then many others, is just the event when we learn something about a physical property of a physical It doesn't "happen immediately everywhere" because it doesn't "happen" at all. It's part of the understanding of the person interpreting QM. In par How does von neumann explain wave function collapse? No experiment to date has uncovered any finite speed for this collapse. Our mind also has memory. We measure x,y,z,t of There is no way to tell if wavefunction collapse is immediately everywhere (whatever that might mean in a relativistic universe), because wavefunct Does wave function collapse happen instantaneously? 1 : to fall or shrink together abruptly and completely : fall into a jumbled or flattened mass through the force of external pressure a blood vessel that collapsed. Measuring the value of one dynamic variable forces all other linked variables to collapse into specific values instantaneously. Does wave Yes the collapse of a wave function is instantaneous. The standard experiment to demonstrate quantum entanglement The standard experiment to dem View the full answer So, in the light of hidden variables, the wavefunction collapses all over space instantaneously indeed. when we measure some measurable value the wave function collapses immediately everywhere. When I studied physics (30 years ago), this concept stopp "The so-called collapse does not happen instantaneously, " Yes, it does in standard quantum mechanics. " This interaction is called an observation, and is the essence of a measurement in quantum mechanics, which connects the wave function with classical observables such as position and momentum. That isn't really the right question to ask. We never measure wave functions. We measure properties like position, momentum, energy of an electron. Does wave function collapse happen instantaneously? That isn't really the right question to ask. To understand this, you have to give up your classical intuition and think about quantum entanglement and measurement. The "collapse of the wavefun The wave function collapse is instantaneous. it is a continuous process of passing from quantum evolution Upon measurement, that is, this interaction, the probabilities calculated by the wave function instantaneously convert to a 100% probability for the specific dark spot and No experiment to date has uncovered any finite speed for this collapse. Why does measurement collapse the wave function? x,y,z,t are mind variables. They exist as physical variables in the physical system of our mind. Or does in happen instantaneously in theoretical terms. We never measure wave functions. The collapse of states or wave functions is traditionally related to 'observations'. However there are several common natural systems where states collapse by themselves. Human consiousness or awareness is not relevant at all. You could just make a measuring device that didn't show the results and the measured system would still collapse. What is a wave function? It is a mathematical function depending on energy and momentum or space and time, $(p_x,p_y,p_z)$ or $(x,y,z,t)$ There are no theories describing wave function collapse. The concept is pure interpretation and in my opinion problematic. Wave functions are fully Yes the collapse of a wavefunction is instantaneous. What is - Quora Answer (1 of 11): There is at Does a wave function collapse to an eigenstate? Does the wavefunction in Quantum Mechanics collapse instantaneously when we measure an observable or is there a transition time between states?
