qrng: using the quantum number generator server

In edzer/qrng: interface to the qrng quantum random number generator

Description

using the quantum number generator server

Usage

 
quantum_runif(n, min = 0, max = 1,..., user, password)
setup_QRNG(user, password, ssl = TRUE, bufsize = 1e5)
QRNG_seed(user, password)

Arguments

n	number of random numbers to generate
min	minimum value
max	maximum value
user	user name; see note
password	password; see note
ssl	boolean; use SSL (secure, encrypted) connection
bufsize	integer; amount of random numbers per request to RNG
...	ignored

Value

quantum_runif returns a numeric vector of length n with random numbers uniformly distributed between min and max.

setup_QRNG sets up the connection to the quantum random number generator and has as side effect that subsequent random numbers in R are taken from this random number generator, e.g. those produced by runif and the like. See Random.user to find out how this works.

QRNG_seed returns an quantum random integer that can be used to seed another random number generator, see set.seed

Note

Registered users (see https://qrng.physik.hu-berlin.de/) can obtain random number streams from a quantum random number generator, which “provides randomness [...] based on the fundamental laws of nature.” Registration is used to avoid that a single user dominates a shared resource (bandwidth).

Examples

# fill in correct user and password, or set them by
# options("qrng.user" = "my_user")
# options("qrng.password" = "my_password")
source("~/.Rprofile")
quantum_runif(100)
setup_QRNG()
# your quantum random numbers are now produced by:
runif(10)
