Obtaining a quantized electrical current would enable the redefinition of the electrical quantities in the SI-unit system. In addition, studying the error sources of the current quantization reveals information about the physics behind the devices. We present current quantization obtainable with the so-called SINIS turnstile. We have observed the electromagnetic environment, two-electron Andreev tunneling and the quasiparticle excitations to give rise to errors in these devices. We present the experiments revealing these error sources and show that by proper design, these error sources are suppressed. Furthermore, understanding the error sources allows us for example to probe electron-phonon interaction in superconducting state and to realize experimentally a Szilard’s engine.
