First Claim
Patent Images
1. A quantum random number generation system comprising:
- a source of light output as a plurality of coherent states such that each state has an indeterminate number of photons;
a photodetector arranged to receive the light output from the light source and to generate a photocurrent dependent on the number of photons in each coherent state; and
processing circuitry connected to receive the photocurrent and arranged to convert it to generate a sequence of random numbers.

13. A method of generating random numbers comprising:
-
outputting a plurality of excited coherent states from a source of light, the coherent states excited such that each state has an indeterminate number of photons; receiving the light output at a photodetector and generating a photocurrent by the photodetector, said photocurrent having a variance dependent on the number of photons in each coherent state; and using the photocurrent at processing circuitry to generate a sequence of random numbers. - View Dependent Claims (14, 15, 16)
