Independent quality assessment of a commercial quantum random number generator

Optical Quantum Random Number Generator

A physical random number generator based on the intrinsic randomness of quantum mechanics is described. The random events are realized by the choice of single photons between the two outputs of a beamsplitter. We present a simple device, which minimizes the impact of the photon counters’ noise, dead-time and after pulses. Random numbers are employed today as well for numerical simulations as fo...

A self-testing quantum random number generator

The generation of random numbers is a task of paramount importance in modern science. A central problem for both classical and quantum randomness generation is to estimate the entropy of the data generated by a given device. Here we present a protocol for self-testing quantum random number generation, in which the user can monitor the entropy in real-time. Based on a few general assumptions, ou...

Quantum Statistical Testing of a Quantum Random Number Generator

The unobservable elements in a quantum technology, e.g., the quantum state, complicate system verification against promised behavior. Using model-based system engineering, we present methods for verifying the operation of a prototypical quantum random number generator. We begin with the algorithmic design of the QRNG followed by the synthesis of its physical design requirements. We next discuss...

High Quality FPGA Optimized Random Number Generator

In this paper we designed a new type of Random number generator by using shift registers and LUT with D-FF as input to it. The algorithm used to generate random numbers is realized using simple xor circuit and implemented on a Virtex II FPGA from Xilinx. This designed block indicate a good sequence of random numbers which is used in high-speed data processor, Testing Instruments, Finding Laser ...
