Question

How do measurements collapse quantum wavefunctions?
​

Answer 1

Answer:

In quantum mechanics, wave function collapse occurs when a wave function—initially in a superposition of several eigenstates—reduces to a single eigenstate due to interaction with the external world. ... Historically Werner Heisenberg was the first to use the idea of wave function reduction to explain quantum measurement.
