Quatnum Random

Basic information

Here you can find simple Python, R, C and Java libraries for the purpose of producing radnom numbers from the quatum source. Organization providing source infromation is ANU QRNG through their API. If you use this library on the daily basis or for commercial purpose, I am encouraging you to donate to this people for ther work. Those guys and girls gave tremendous contribution to humanity and modern world by giving this informations for free.

Why Quantum Random

Every programming language(at least that I know of) contains feature for generating random numbers. Though, those numbers are not random in real meaning of the word. Random numbers that you can generate through C, Java, Pyton... are generated using speciffic algorithm. In other word, in this way generated numbers are calculated, what makes them not random, but rather, random from human perspective.

Only way to get reall random numbers using modern day technology is from quantum source. From web site of ANU QRNG you can find out more, how phisics behind all this works.

How to use

• With Python you have to instantiate object QuantumRand. In the class contructor, firs time is called function next that returns random integer.

  • getRand call to get random integer. getRand have two optional paramethers min for minimal value and max for maximal values that should be returned.
  • getFloat to get random decimal value in between 0 and 1. getFloat have only decimal paramether to format return value with exact number of decimal places.
  • next to generate new random value from the same object.

• With R

  • getRand with paramethers minv for minimal value and maxv for maximal value, that returns random integer value. With R those paramether are mandatory.
  • getFloat returns random value in between 0 and 1 with paramether decimal to describe how many decimal places should be in return value.

  Every time you call getRand or getFloat new random value is generated.

• With C first you have to call function QuantumRand_next to generate random value. Then you can use this long value for your purposes or to call some of specialized functions.

  • QuantumRand_next_min have paramether min that allows you to set minimun for returning value.
  • QuantumRand_next_max have paramether max that allows you to set maximum for returning value.
  • QuantumRand_next_min_max have both min and max paramethers.
  • QuantumRand_get_float function returns float value in between 0 and 1.
  • QuantumRand_next to generate new random value.

  In Makefile, there are example of how you can compile shared object from the code from QuantumRand.h but I believe that the best course of action would be just to include this header file in new object and to compile it with it. QuantumRand.h depends on libcurl and libjson-c libraries.

• With Java same as with Python, first you will have to instantiate object QuantumRand. At the same time you will generate first random value for that object to work with.

  • next will create new random value and return it.
  • getLong will return present random value for that object.
  • getLong(min, max) is overloaded getLong function that allows you to determine minimal and maximal random value.
  • getFloat will return double in between 0 and 1.
