ABSTRACT:
We propose a computer method for analyzing physical systems that exhibit quantum mechanical behavior. To analyze a quantum system according to the method of the present invention, one performs the following steps: First, one enters into the computer some information about the physical system by portraying it on the computer screen as a special type of graph (diagram). Next one enters into the computer additional information that is not contained in the graph. Part of this non-graph information is a matrix of complex numbers for each node of the graph. Finally, the computer uses the entered information to do calculations and it outputs the result of these calculations. The computer output consists mainly of conditional probabilities for the outcomes of measurements performed on the quantum system. The method that we are proposing is similar to the method used in the field of Classical Bayesian Nets (also known as Causal Probabilistic Nets). However, the method of Classical Bayesian Nets does not describe quantum systems correctly, whereas our method does.
