The DRDO Young Scientist Laboratory has developed a Quantum-based technology to generate Random Numbers.
♦ DYSL-QT has developed a Quantum Random Number Generator (QRNG), which can detect random quantum events and convert them into a stream of binary numbers.
♦ The laboratory has developed a fibre optic branch path based on QRNG.
♦ QRNG based on branch path is based on the following principle: if a single photon is an incident on a balanced beam splitter, it will randomly adopt any beam splitter’s output path.
♦ Since the path chosen by the photon is random, the randomness is converted into a series of bits.
Random numbers play an important role in many fields, such as quantum communication, cryptography (key generation, key packaging, identity verification, etc.), scientific simulation, lotteries and fundamental physics experiments. The generation of genuine randomness is generally considered impossible with classical means. Quantum mechanics has the inherent potential to provide real random numbers, so it has become the first choice for scientific applications that require randomness.
