Suppose two particles or molecules are generated (produced) together. If one molecule is taken away from the another, let us say to another city. If we make some certain changes in anyone of them, e.g if we change its motion if it was in clock wise and we change it to anti-clock wise. So by making changes in each of them the another one adopts the change itself. WHY?

This doesn't happen, even with entangled particles.

Making a change to a particle here in a pure state (such knowing it is "clockwise" in your example) never changes its entangled partner. Since it is in a pure state, it is not entangled on that basis. Further, if it is in a superposition on a particular basis, you can gain information about it but cannot do anything more than gain the same information about the other one. You can't make it be "clockwise" and transmit that to the other particle.
 
I think so it doesn't happen normally. But the biggest reasearch ever done and costed billions of dollars was this. The research was based on it, why the one effects the another?

Uh, sorry, no such thing happened. I wish even millions were spent. :smile:

Perhaps you have a reference, as around here we like to deal with factual information where possible.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...
According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
