Twin Degenerate OPO for Quantum Random Bit Generation
Alireza Marandi, Nick C. Leindecker, Konstantin L. Vodopyanov, Robert L. Byer · Nonlinear Optics · 2011
We propose a new quantum random bit generator based on degenerate synchronously pumped optical parametric oscillators. The intrinsic randomness is due to the phase of noise photons. The resulting bit sequence satisfies statistical randomness tests.
