Jul 17, 2013  · Physicists publish solution to the quantum measurement problem. In their recent opus magnum, Theo Nieuwenhuizen (Institute of Physics, UvA) and colleagues claim to have found a solution to the so-called quantum measurement problem. This subject of measurement in quantum mechanics was studied by many prominent scientists, including Heisenberg,

The measurement problem in quantum mechanics is the problem of how wave function collapse occurs. The inability to observe such a collapse directly has given rise to different interpretations of quantum mechanics and poses a key set of questions that each interpretation must answer. The wave function in quantum mechanics evolves deterministically according to the Schrödinger equation as a linear.

Responses to the Measurement Problem. One of the largest of the recent literatures in philosophy of quantum theory has sought to resolve the measurement problem and we can only have the briefest glimpse of them here. Generally speaking, most of those responses fall into five groups. 1. Accept the standard account.

These simulators are designed to explore specific properties of quantum physics by modelling how the smallest particles in the universe might behave. This in turn can be applied to solve complex.
