Quantum random number generator using photon-number path entanglement
Osung Kwon, Young-Wook Cho, Yoon-Ho Kim · Applied Optics · 2009
We report a quantum random number generator based on the photon-number-path entangled state that is prepared by means of two-photon quantum interference at a beam splitter. The randomness in our scheme is truly quantum mechanical in origin since it results from the projection measurement of the entangled two-photon state. The generated bit sequences satisfy the standard randomness test.
