Detailed explanation-1: -DRDO Young Scientist Laboratory for Quantum Technologies (DYSL-QT), Pune has developed Quantum Random Number Generator (QRNG) exploiting the principles of Quantum Physics to generate true randomness.

Detailed explanation-2: -In 1951, a random number generator was first added to a general-purpose computer, the Ferranti Mark 1. The Mark 1 shipped with a built-in random number instruction that could generate 20 random bits at a time, using electrical noise. The feature was designed by the grandfather of computing, Alan Turing.

Detailed explanation-3: -What is a quantum random number generator? It is a hardware component that is used to generate unpredictable random numbers, typically for cryptography or computation applications.

Detailed explanation-4: -The method generates digital bits (1s and 0s) with photons, or particles of light. An intense laser hits a special crystal that converts laser light into pairs of photons that are entangled, a quantum phenomenon that links their properties. These photons are then measured to produce a string of truly random numbers.

Detailed explanation-5: -As for random number generator algorithms that are executable by computers, they date back as early as the 1940s and 50s (the Middle-square method and Lehmer generator, for example) and continue to be written today (Xoroshiro128+, Squares RNG, and more).
