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)
NASA will pay up to $1 million to people who can come up with innovative and sustainable food production ideas to feed astronauts in space, as the US space agency prepares to send astronauts further into the cosmos than ever before. Giving future explorers the technology to produce nutritious, tasty, and satisfying meals on long-duration space missions will give them the energy required to uncover the great unknown. In coordination with the Canadian Space Agency, NASA has launched the 'Deep Space Food Challenge' that calls on teams to design, build, and demonstrate prototypes of food production technologies that provide tangible nutritional products -- or food.

"Feeding astronauts over long periods within the constraints of space travel will require innovative solutions," said Jim Reuter, associate administrator for NASA's Space Technology Mission Directorate in Washington, DC. "Pushing the boundaries of food technology will keep future explorers healthy and could even help feed people here at home," he said in a statement. Over time, food loses its nutritional value. That means for a multi-year mission to Mars, bringing along pre-packaged food will not meet all the needs for maintaining astronaut health.

In October 2021, Phase 1 of the challenge culminated as NASA awarded 18 teams a total of $450,000 for their concepts for innovative food production technology that produces safe, acceptable, palatable, nutritious food products. NASA now invites both new and existing teams to enter Phase 2 for a prize purse up to $1 million. "Everything needed to store, prepare and deliver food to the crew, including production, processing, transport, consumption, and disposal of waste should be considered," said NASA. Proposed technologies such as plant growth systems, manufactured food products, and ready-to-eat solutions combined could provide the future crews with a variety of options that would provide the needed daily nutrition, it added.

People suffering from depression are more likely to believe vaccine-related misinformation, according to a new study. The study found that people with moderate or greater symptoms of depression were more likely to believe at least 1 of 4 false statements about Covid-19 vaccines.
Those who believed the statements to be true were half as likely to be vaccinated, the study, published in the Journal of the American Medical Association, indicated. 'It is clear the pandemic has taken a heavy toll on the mental health of Americans, especially young people," said researcher Katherine Ognyanova from Rutgers University, the US.

According to the National Center for Health Statistics, approximately one-quarter of adults in the US have consistently reported moderate or greater depressive symptoms during the Covid-19 pandemic. The findings suggest that people suffering from depression may be at a higher risk of Covid-19, highlighting the need to address mental health disorders.
For the study, the team used data from the research group The Covid States Project, which conducted surveys approximately once every six weeks since April 2020. The researchers analysed data from 15,464 adults in the US and the participants were asked to rate vaccine-related misinformation as accurate (statement is true), inaccurate (statement is not true) or not sure.

The four statements of misinformation included "The Covid-19 vaccines will alter people's DNA", "The vaccines contain microchips that could track people", "The vaccines contain the lung tissue of aborted fetuses", and "The -19 vaccines can cause infertility, making it more difficult to get pregnant". The survey participants completed a health questionnaire to measure major depressive symptoms over two weeks. (IANS/ MBI)

The space economy is on track to be valued at a trillion dollars by the end of 2030, but assets such as navigation, weather and communication satellites that serve our society daily are threatened by space debris, an Indian-American professor has stressed. According to NASA, it is estimated that millions of pieces of space debris orbit around Earth. A major portion of these objects as well as active satellites reside in the low-Earth orbit region, at altitudes between 200 km and 1,000 km. In November last year, Russia destroyed one of its own satellites with a ground-based missile, creating thousands of pieces of debris that passed through the International Space Station (ISS).

The astronauts and cosmonauts had to take shelter in their Soyuz and Dragon vehicles docked at the space station, as the orbital lab continued to pass through a debris field every 90 minutes. The US identified more than 1,500 trackable pieces of debris from the event, and many thousands of smaller ones couldn't be traced. According to Piyush Mehta, Assistant Professor of mechanical and aerospace engineering at West Virginia University, the US, in low-Earth orbit, our ability to safeguard these space assets depends on modelling of the aerodynamic forces acting on the satellites, specifically satellite drag.

"The drag force acting on a satellite is affected by various physical parameters, however, the most crucial and uncertain are the drag coefficient and mass density," said Mehta, who leads a collaborative effort on satellite drag coefficient modelling under the International Space Weather Action Teams (ISWAT) initiative. Mehta explained that because of the interconnectedness of the two parameters, one of them is held constant, typically the drag coefficient, while the other is investigated.
However, he added that this causes inconsistencies or inaccuracies in our understanding of the mass density variability in the upper atmosphere or thermosphere. Jason Gross, Interim Chair of mechanical and aerospace engineering at the Statler College, West Virginia University, said: "With the continued rapid increase of manmade satellites in low-Earth orbit, his (Mehta's) work towards improved orbital decay prediction becomes more important for the future of space environment sustainability with each passing day. His lab is at the forefront of this important field." (IANS/SP)
