Efficient Raman generation in a waveguide: A route to ultrafast quantum random number generation

Efficient Raman generation in a waveguide: A route to ultrafast quantum random number generation. England, D., Bustard, P., Moffatt, D., Nunn, J., Lausten, R., & Sussman, B. Applied Physics Letters, 2014.

Paper doi abstract bibtex

The inherent uncertainty in quantum mechanics offers a source of true randomness which can be used to produce unbreakable cryptographic keys. We discuss the development of a high-speed random number generator based on the quantum phase fluctuations in spontaneously initiated stimulated Raman scattering (SISRS). We utilize the tight confinement and long interaction length available in a Potassium Titanyl Phosphate waveguide to generate highly efficient SISRS using nanojoule pulse energies, reducing the high pump power requirements of the previous approaches. We measure the random phase of the Stokes output using a simple interferometric setup to yield quantum random numbers at 145 Mbps. Â© 2014 AIP Publishing LLC.
