Abstract

According to the Machida-Namiki theory a physical information can be acquired from quantum measurement processes by averaging quantum events over many-Hilbert spaces. The averaging process causes an irreversibility. In this paper several numerical simulations were performed to testify how quantum coherence is lost during measuring processes and how the reduction of wavepacket is eventually caused.
