Abstract (in Japanese) (See Japanese page) 
(in English) Physical random numbers generated by using quantum measurement are in principle impossible to predict.We have demonstrated generation of physical random numbers by measuring quadrature amplitudes of vacuum states with a broadband homodyne detector.In this method, random numbers can be generated at 500Mbps.By multiplying a toeplitz matrix to the generated numbers, we generated physical random numbers that passed all the test of TestU01 crush test.
