1. 1. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution

   Kandidat-uppsats, Lunds universitet/Statistiska institutionen

   Författare :Marcus Stolz; Jonathan Christopher; [2024]
   Nyckelord :Monte Carlo integration; Quasi monte carlo integration; Random number generation; Mathematics and Statistics;

   Sammanfattning : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). LÄS MER

3. 2. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Martin Clason; [2023]
   Nyckelord :shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

   Sammanfattning : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. LÄS MER

4. 3. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Oscar Pihl; [2023]
   Nyckelord :spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

   Sammanfattning : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

5. 4. Exploring true random number generators Build on commercial-off-the-shelve Components

   M1-uppsats, Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Författare :Linnéa Mörk; [2023]
   Nyckelord :TRNG; RNG; Random number generator; commercial-off-the-shelve;

   Sammanfattning : Generating random numbers can be accomplished through various methods, with the primary distinction lying between pseudo-random number generators (PRNGs), which are commonly used for applications that require a large amount of random data, and true random number generators (TRNGs), which are commonly used for applications that need security and unpredictability. This thesis explores the feasibility of harnessing frequency variations in the electrical grid as a source of entropy for a TRNG. LÄS MER

7. 5. Evolved cellular automata for 2D video game level generation

   Kandidat-uppsats, Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Författare :Amir Khodabakhshi; Adel Sabanovic; [2022]
   Nyckelord :Procedural content generation; PCG; cellular automata; genetic algorithm; evolved cellular automata;

   Sammanfattning : Manual design of levels can be an expensive and time consuming process. Procedural content generation (PCG) entails methods to algorithmically generate game content such as levels. One such way is by using cellular automata (CA), and in particular evolved cellular automata. LÄS MER
