Modeling Feynman's quantum computer using stochastic high level Petri nets

Abstract

One of the first and simplest models of a quantum computer was introduced in 1985 by Richard Feynman. The aim of our study is to extend the application area of Petri Nets, which have been very successfdly used to model classical engineering systems, by modeling the use and operation of Feynman's quantum computer. Originally, Feynman could not give a time bound for the completion of his computer's computation; a periodical measurement procedure was needed giving rise to a specific computational approach. We have chosen Feynman's NOT-computer, in the form of two gates in series, as our object of demonstration; its use and operation have been modeled in detail using Stochastic High Level Petri Net formalism.

Performance Analysis of SyncML Server System Using Stochastic Petri Nets

“…To evaluate the performance of the implemented server, we use SPNP 6.0 which is based on a stochastic Petri net model [7], [8]. In this model, we define the arrival rate (λ), service processing rate of the sync adapter (µ), memory size (pM), and number of concurrent DB connections (pDB).…”
