Thanks to government funding, Indian physicists are preparing for a deep dive into the quantum world that holds the secrets for developing exciting technologies for computing, communication, cryptography and many more.

Schemes for making India a major player in quantum technologies were deliberated during a five-day international conference on “Quantum Frontiers and Fundamentals” at the Raman Research Institute (RRI) here.

Sponsored by the John Templeton Foundation, the philanthropic organisation in the US, it was attended by eminent physicists from India and abroad, including several research students from India with a total number of around 100 participants, reflecting the significant growth in the research community in this area in our country.

“This is an interesting conference, blending quantum fundamentals aspects with applications, and is unique in its mandate as we have tried to provide equal emphasis to both theoretical research and experimental quantum technologies,” Urbasi Sinha, of RRI and organiser of the conference, told this correspondent. Dipankar Home of the Bose Institute, Kolkata, and Alexandre Matzkin of the French National Center for Scientific Research (CNRS) in Paris were the co-organisers.

Quantum physics is a basic theory in physics that deals with the behaviour of matter and light on the atomic and subatomic scale. Quantum technology exploits the weird properties of quantum mechanics — especially quantum entanglement, quantum superposition and quantum tunnelling — into practical applications for computing, cryptography and “secure” communication. Quantum computers that process “quantum data” (instead of binary data) are predicted to be faster than today’s largest classical computer.

Research in these areas at Indian laboratories has received a boost with promised funding support from the government’s Department of Science and Technology (DST) and the Indian Space Research Organisation (ISRO), as well as small individual projects from the Defence Research and Development Organisation and the Prime Minister’s Office.

The DST’s Mission-Mode scheme, called “Quantum Science and Technology (QuST)”, will fund research “for the development and demonstration” of quantum computers, quantum communication and cryptography, besides “demonstration of quantum teleportation”.

The scheme, DST says, “promises to revolutionise the future computation and communication systems which will ultimately have huge impact on the nation and our society as a whole”.

The DST initiative has received overwhelming response and “has already received 128 proposals from researchers from different parts of the country,” Rajeev Sharma, a spokesperson for the scheme at DST, told this correspondent. “Funding is no problem,” he said.

ISRO, in collaboration with RRI, has initiated a mega project called “Quantum Experiments Using Satellite Technology (QUEST)”. Sinha, along with members of her “Quantum Information and Computing Lab” and theory colleagues at RRI, will play a key role in developing these technologies in the coming years, with support from ISRO.

“Once RRI is ready with an experimental payload, we will launch it on board one of our satellite missions,” M. Sankaran, deputy director of ISRO Satellite Centre in Bengaluru and one of the conference participants, told this correspondent.

According to Sinha, one of her first experiments “will be a collaborative effort with the ‘Quantum Photonics Lab’ at Ontario’s University of Waterloo” that will aim to establish “a secure Quantum Key Distribution link” between India and Canada.

“It is good that both DST and ISRO have decided to fund research in this important area,” said Arun Kumar Pati, a leading researcher in quantum physics at the Harish Chandra Research Institute in Allahabad and a conference participant. “We are 10 years behind and have to catch up.”

Using its world’s first quantum satellite called “Micius”, China had already demonstrated transmission of images from the country to Austria and researchers at the National University of Singapore had built a nano-satellite with a quantum communication payload. Scientists of the University of Waterloo have also demonstrated the first quantum key distribution transmissions from a ground transmitter to a quantum payload on a moving aircraft.

The conference suggested the formation in India of a society for quantum information scientists. It also called for greater thrust to experimental research and an increase in the pool of researchers in the area of quantum technologies. (IANS)

  • India’s huge strides in the field of Space program is the result of extensive rersearch work done by many famous Indian scientists

Science is something we are surrounded very briskly. Science has occupied us more aggressively than we can ever assume even. From our regular cellphone to innovative technologies of the 21st century, from our smart homes to space technology, it all fits into science and technology. We can’t imagine a day without the assistance provided by the science.

India has come up a long way in the field of science and technology. The invention of zero and the discovery of ‘Raman Effect”, are all credited to Indian scientists, as they have immensely contributed to their research works.

To appreciate the bliss of such comfort, we have compiled a list of fifteen famous Indian scientists who have changed the whole scenario of living and even achieved global recognition for their immense support to the humanity.

1. Vikram Sarabhai

Vikram Sarabhai is considered as the Father of India’s space program. He was born on 12 August 1919. Vikram Sarabhai’s contribution to the Indian space program is well-known. He was the sole man behind the establishment of Indian Space Research Organization (ISRO), Indian Institute of Management, Ahmedabad (IIM-A) and the Nehru Foundation for Development.

He was honoured with many prestigious awards including Shanti Swarup Bhatnagar Medal in 1962, Padma Bhushan in 1966 and Padma Vibhushan (posthumously) in 1972

2. APJ Abdul Kalam

The former President of India, Avul Pakir Jainulabdeen Abdul Kalam was elite spearhead scientist of India. His contribution remains indispensable in the field of defence and missile programs.  He worked for two of the most decorated Indian institutes, one as the Defense Research and Development Organization (DRDO) and other one is Indian Space Research Organization (ISRO).

Abdul Kalam was born on October 15, 1931. In one of his books, he talked about making India a developed nation by 2020. Abdul Kalam’s love for young generation can be gauged by the fact that he had set a goal of meeting 100,000 students in 2 years after his resignation from the role of scientific adviser in 1999.

Abdul Kalam kick-started his career with designing a small helicopter for the Indian Army. After that, he was moved to the Indian Space Research Organization (ISRO) as the project director of India’s first indigenous Satellite Launch Vehicle (SLV-III).  The program resulted in the successful deployment of the Rohini satellite in earth’s orbit in July 1980.

3. Homi Bhabha

Homi Bhabha is acknowledged as the father of Indian nuclear power. Homi Jehangir Bhabha is better known as Homi Bhabha. He was born on October 30, 1909, in Bombay. He is known for his crucial role in the Quantum Theory.

He started his scientific career in nuclear physics from Great Britain. After completing his education in London, Homi Bhabha returned to India and convince the Congress Party’s senior leaders, especially Jawaharlal Nehru, to start the indigenous nuclear programme. Although, he was very much against the development of atomic bombs, even if the country had enough resources to do so. He rather advocated the use of nuclear energy to wave off India’s misery and poverty.

Finally, Homi Bhabha was decorated as the Chairman of the Atomic Energy Commission of India.

Once Satyendra Nath sent a short article on “Planck’s Law and the Hypothesis of Light Quanta” to Albert Einstein. Interestingly, this article was accepted by Einstein and translated into German. Later it got published in Zeitschrift für Physik under Bose’s name, in 1924. Satyendra Nath also gave a lecture at the University of Dhaka on the theory of radiation and the ultraviolet catastrophe.

The Rabindranath Tagore’s book on science, ‘Visva–Parichay’ was dedicated to him in 1937. Satyendra Nath was also awarded India’s second highest civilian award, the Padma Vibhushan in 1954.

9. CV Raman

Chandrasekhara Venkata Raman is popularly known as CV Raman and was an Indian scientist. He was born in Tiruchirapalli on November 7, 1888. CV Raman won the Nobel Prize in Physics in 1930 for his pioneering work on scattering of light. He was the first Asian and first non-White to receive any Nobel Prize in the sciences.

His other works include the working of the acoustics of musical instruments. CV Raman was the one who probed into the sound of the Indian drums such as the Tabla and the Mridangam. “Raman scattering” still remains most accepted and notable work of CV Raman. He explained that, when light passes through a transparent material, some of the deflected light changes into wavelength and this causes “Raman Effect”.

Unfortunately, in October 1970, he fell unconscious while working and was immediately moved to a hospital. Doctors advised him to stay there but he was adamant about moving to his Institute (the Raman Research Institute in Bangalore) and live his last moments in the vicinity of flowers of his institute. He was laid to rest on 21 November 1970.

Before taking his last breath, CV Raman uttered, “Do not allow the journals of the Academy to die, for they are the sensitive indicators of the quality of Science being done in the country and whether science is taking root in it or not.”

10. Srinivasa Ramanujan

Ramanujam was an Indian mathematician who, with almost no formal training in pure mathematics, made extraordinary contributions. His work includes mathematical analysis, number theory, infinite series, and continued fractions.

Ramanujam was born on December 22, 1887, and by age 11, he hushed up the mathematical knowledge of two college students who were lodgers at his home.

By the age of 13, he mastered a book on advanced trigonometry written by S. L. Loney and came up with his own theorems.

During his stay in England, Ramanujam faced a lot of health problems due to the scarcity of vegetarian food. After that, he came back India and died at the age of 32.

Tamil Nadu celebrates 22 December (Ramanujan’s birthday) as ‘State IT Day’, memorializing his unprecedented feats in mathematics.
