Increased Certification of Semi-device Independent Random Numbers using Many Inputs and More Postprocessing

Understand

Quantum communication with systems of dimension larger than two provides advantages in information processing tasks.

• Examples include higher rates of key distribution and random number generation.
• The main disadvantage of using such multi-dimensional quantum systems is the increased complexity of the experimental setup.
• Here, we analyze a not-so-obvious problem: the relation between randomness certification and computational requirements of the postprocessing of experimental data.
