Another Milestone For India: DRDO Lab Develops Crucial Quantum Based Tech For Random Number Generation DRDO Logo (Pic Via Wikipedia) The Defence Research and Development Organisation (DRDO) has developed a Quantum Random Number Generator (QRNG) which detects random quantum events and converts those into a stream of binary digits. Random numbers have essential roles in many fields, such as quantum communication, cryptography (key generation, key wrapping, authentication etc), scientific simulations, lotteries and fundamental physics experiments. The generation of genuine randomness is generally considered impossible with classical means. Quantum Mechanics has the inherent potential of providing true random numbers and thus has become the preferred option for the scientific applications requiring randomness, an official release said.
