@article{Tebyanian2020SemideviceindependentRF, title={Semi-device-independent randomness from d -outcome continuous-variable detection}, author={Hamid Tebyanian and Marco Avesani and Giuseppe Vallone and Paolo Villoresi}, journal={Physical Review A}, year={2020} }

Recently, semi-device independent protocols have attracted increasing attention, guaranteeing security with few hypotheses and experimental simplicity. In this paper, we demonstrate a many-outcomes scheme with the binary phase-shift keying (BPSK) for a semi-device independent protocol based on the energy assumption. We show in theory that the number of certified random bits of the d-outcomes system outperforms the standard scheme (binary-outcomes). Furthermore, we compare the results of two…
