IIT Guwahati scientists have made the institution proud once again as they got international recognition for their contribution to ‘Quantum Engtanglement.’

IIT Guwahati scientists led by Professor Amarendra Kumar Sarma from Department of Physics and his research scholars Dr. Subhadeep Chakraborty and Mr. Sampreet Kalila have studied the workings of quantum entanglement.

IIT Guwahati scientists win great global recognition

IIT Guwahati scientists summarised their understanding in an invited review article in a prestigious research journal ‘AVS Quantum Science’ which is published by American Institute of Physics.

The article of IIT Guwahati Scientists is published as a feature article in the journal this month.

Professor Sarma who is one among the IIT Guwahati scientists was invited to write a review article for the journal in recognition to his seminal works in quantum optics.

IIT Guwahati scientists published their research articles in the area of quantum optics in various prestigious journals such as Physical Review A, Journal of Optical Society of America B, Annals of Physics, Scientific Reports.

Couple of recent works by Professor Sarma who led the IIT Guwahati scientists are available on the links given below:

Quantum physics, the field of Science that has ridden on the shoulders of such giants as Niels Bohr, Werner Heisenberg, and Erwin Schrödinger, continues to be researched by labs all over the world, to help unravel the workings of the universe, say IIT Guwahati scientists.

This study of subatomic particles and forces forms the basis of the computer chip, the electric current, laser power, and even light from the sun, say the IIT Guwahati scientists.

IIT Guwahati scientists further said one of the most fascinating and perhaps bizarre traits of quantum mechanics is quantum entanglement, the interaction among quantum systems such as subatomic particles, in ways not possible in our larger, perceivable classical world.

When two subatomic particles, like a pair of electrons, are entangled, it is impossible to measure properties of one without affecting the other.

No matter how far they move apart, if one is tweaked, measured, or observed, the other seems to instantly respond, even if the whole world now lies between them.

It is the same phenomenon that baffled even the mind of well-known scientific genius Albert Einstein, said Professor Sarma, who led the team of IIT Guwahati scientists.

That, however, does not make it unreal – numerous experiments have established that entanglement is indeed a real phenomenon in subatomic systems, said Professor Amarendra Kumar Sarma who led the team of IIT Guwahati scientists.

In fact, quantum entanglement is the building block of the second generation of quantum technology such as quantum computation, quantum cryptography, quantum teleportation, and quantum dense coding, added Prof. Sarma who led IIT Guwahati scientists.

Various research groups around the world are working towards understanding quantum entanglement across various subfields.

IIT Guwahati scientists comprising Dr. Sarma and his team works on understanding it in the realm of cavity optomechanics, the interaction between light and mechanical objects at low-energy scales.

Speaking further Professor Sarma said in simplified terms, a cavity optomechanical system refers to a set of mirrors where one of the mirrors is fixed while the other one is slightly movable.

‘Such systems provide a universal tool to achieve quantum control of mechanical motion.’

But beyond application, the research helps to understand the boundary between classical and quantum physics, said Professor Sarma who led the team of IIT Guwahati scientists.

‘We have come up with various practical schemes to enhance quantum correlations in optomechanical systems.’

Apart from entanglement we are looking into the aspects of qubit transfer, photon and phonon blockade also in such systems owing to their tremendous applications in quantum communication and information sciences,’ Dr. Sarma who is the lead among IIT Guwahati scientists.

More recently, scientists have addressed the issue of ‘entanglement sudden death’ under the influence of a local noisy environment, a stumbling block encountered by scientists a decade ago.

The researchers have proposed a scheme to tackle such shortcomings using an optomechanical platform.

The scientists have published their work in prestigious journals of Physics.

The recently featured article of the scientists in AVS Quantum Science has provided them the impetus for more rigorous research in unravelling the mysteries of quatum entanglement and other quantum optical phenomena.

JEE Mains 2025 Application

The exam will have three papers, Paper 1, Paper 2A, Paper 2B. Paper 1 of JEE Mains 2025 is for students focused on graduation in engineering (BE or BTech).

Students keen on studying under graduation in architecture (BArch) have to appear for Paper 2A, those who wish to study graduation in planning (BPlan) have to appear for Paper 2B.

Admission Open in LPU for 2025

Architecture aspirants have also to answer questions related to creativity, innovation, drawing along with that of maths, physics and chemistry.

Format of questions will be multiple choice where every question has more than one reply option and the right one has to be chosen for getting marks.

Who can submit JEE Mains 2025 Application?

Students who have passed plus-two from a recognized educational institution with subjects as maths, physics and chemistry can take up JEE Mains 2025 application submission.

Even students who have appeared for the plus-two exams and are waiting for results or who are about to appear for the qualifying exam can also submit JEE Mains 2025 application.
