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

QUANTUM RANDOM NUMBER GENERATOR
- Quantum Technologies concerns the study, control and manipulation of quantum principle– based systems with the goal of achieving information processing.
- It is a deeply interdisciplinary field, lying in the cross-over of areas such as quantum physics, condensed matter physics, computer science, mathematics and electrical and electronics engineering.
RANDOM NUMBER GENERATOR
- DAYS after successfully testing the Quantum Key Distribution technology, the Defence Research and Development Organisation (DRDO) has achieved successfully developing a Quantum Random Number Generator (QRNG).
- The DRDO Young Scientist Laboratory for Quantum Technologies (DYSL-QT), a DRDO facility based in Mumbai, has developed a QRNG.
- It 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.
- As the path chosen by the photon is random, the randomness is translated to a sequence of binary digits, also called bits.
- QKD is primarily a mechanism to undertake secure communication, which utilises a cryptographic protocol involving various components of quantum mechanics.
- The whole mechanism thus achieves highly secure communication.
Random numbers have essential roles in various fields :
- The generation of perfect randomness is generally considered impossible with classical methodologies.
- Quantum mechanics has the inherent potential of providing true random numbers and thus has become the preferred option for scientific applications requiring randomness.
- With this development, India enters the club of countries which have the technology to achieve the generation of random numbers based on the Quantum Phenomenon.
- On December 8, the DRDO announced that their Quantum Key Distribution (QKD) technology .
- DRDO underwent a successful trial between two laboratories in Hyderabad, where the quantum technology-based security was validated for a range of 12 km long over a fibre optic channel.
YOUNG SCIENTIST LABORATORIES
- DYSL-QT is one of the five YSLs (Young Scientist Laboratories) of the DRDO which are working on five different technologies.
The other facilities are:
- Artificial Intelligence (DYSL-AI) Bengaluru
- Cognitive Technologies (DYSL-CT) Chennai
- Asymmetric Technologies (DYSL-AT) Kolkata
- Smart Materials (DYSL-SM) Hyderabad.
These five facilities were dedicated to the nation by Prime Minister in January this year.
- Various facilities of the DRDO are currently working on various quantum technology-based applications.
- In December last year, an international symposium on Quantum Information Technology (ISQIT 2019) was held in Pune.
- It was organised by Defence Institute of Advanced Technology (DIAT) of the DRDO, the National Technical Research Organisation (NTRO) and Joint Advanced Technology Centre (JATC) of Indian Institute of Technology, Delhi.
