DRDO Lab Develops QRNG

The DRDO Young Scientist Laboratory for Quantum Technologies (DYSL-QT), a DRDO facility based in Mumbai, has developed a Quantum Random Number Generator (QRNG) which has the ability to detect random quantum events and convert those into a stream of binary digits.

  • The facility has developed a fiber-optic branch path based QRNG.
  • Branch path-based QRNG relies on the principle that if a single photon falls on a balanced beam splitter, it will take either of the beam-splitter output paths randomly. As the path chosen by the photon is random, the randomness is translated to a sequence of binary digits, also called bits.
