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.

      ISSUE: 

The QRNG system developed by the laboratory (DYSL-QT) has passed the global randomness testing standards of NIST and Die-harder Statistical Test Suites at the speed of around 150 kbps after post-processing.

QUANTUM RANDOM NUMBER GENERATOR

QUANTUM TECHNOLOGIES

  • Quantum Technologies concerns the study, control and manipulation of quantum principle– based systems with the goal of achieving information processing.

Ultimate aim is to achieve secure communication and superior sensors beyond the limits of the classical systems 

  • 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.

FEATURES

  • 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.
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.

PRINCIPLE

  • QKD is primarily a mechanism to undertake secure communication, which utilises a cryptographic protocol involving various components of quantum mechanics.

The technology enables two communicating sides to come up with random secret keys shared by both of them and known exclusively to them, and only they can use it to encrypt and decrypt messages
 

  • The whole mechanism thus achieves highly secure communication.

APPLICATIONS

Random numbers have essential roles in various fields :

EXAMPLE
Quantum communication, cryptography applications like key generation, key wrapping, authentication along with scientific simulations, lotteries and fundamental physics experiments.

  • The generation of perfect randomness is generally considered impossible with classical methodologies.

SIGNIFICANCE

  • Quantum mechanics has the inherent potential of providing true random numbers and thus has become the preferred option for scientific applications requiring randomness.

The generated random numbers are also evaluated and verified using DRDO’s indigenously developed Randomness Testing Statistical Test Suite of SAG

  • 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.

      IASbhai WINDUP: 

  • 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.
