Summary:
A device which detects terahertz (THz) electromagnetic waves with smaller in photon energy than visible lights and outputs a single photoelectron has been developed. Employing the devices as THz detectors might provide high sensitivity to sensing and communication systems. The authors has proposed a receiver consisting of three blocks. They are the detector, a frequency discriminator separating the photoelectrons depending on their momentum, a single-electron-transistor-based decoder estimating transmitted data from the streams of the separated photoelectrons. The circuit simulator models of the blocks are necessary to aid the design of the receiver. As a basis of the model of the detector, a one-dimensional multi-particle quantum system is modeled after a classical probabilistic system composed of the Brownian particles in this paper. We confirmed by the numerical experiments of the established model that the Brownian particles moves probabilistically according to the existence probability derived from the wave function of the original quantum system.
