Every day, factories around the world burn fuel, heat materials to extreme temperatures, and then quietly let much of that energy escape into the air. Not as smoke. Not as…

I am an Early Career Scientist at Institute of Nanoscience - National Research Council (CNR - NANO), Pisa, Italy. Currently, I am involve in fabricating the Josephson junction based superconducting diodes and Superconducting Quantum Interference Devices (SQUIDs). I have a Ph.D. in Physics from a National Research Lab (Centre for Nano and Soft Matter Sciences, Bangalore, India), where I have fabricated self-cleaning surfaces, bioinspired structural colors, ultrasensitive biomolecule sensing devices and gas sensors. I like to communicate science to the public by writing blogs, demonstrating scientific models, and invited talks at several platforms.
From Lab to Society: Why Quantum Sensors are Important for India’s Science and Technology Strategy
GPS spoofing poses a significant threat to Indian airlines. Recently, there have been several unfortunate reports of planes having to change their routes before reaching their destination due to GPS…
The Eyes and Ears of the Quantum Age: How Quantum Sensing and Metrology Are Revolutionizing the Quantum Missions
Most major nations are running their own independent quantum missions with the aim of achieving self-reliance in quantum technology. The greatest attention in the field of quantum technologies has been…
How Josephson Junction is the Heart of Quantum Computer?
Quantum computers are expected to tackle problems that classical computers simply can’t solve, for instance, designing next generation drugs for cancer treatment or optimizing complex logistics at scales unmanageable by classical computers. At the center of many of these powerful machines is something surprisingly tiny: the Josephson junction. While it’s not the only way to build a quantum computer, it’s by far the most successful one to date.
Meet Olo: The Invention of a New Colour That Human Eyes Have Never Seen Before
Scientists have just created a new colour named Olo, which does not exist within the visible spectrum detectable by a normal human eye. In an experiment conducted by scientists from the University of California and the University of Washington School of Medicine, a new colour was generated by using laser light to stimulate only a single type of light-sensitive cone in the human eye—a colour never before seen by human eyes. The possible description of this colour is to imagine it as a hyper saturated bluish-green.
What are quantum materials and why are quantum materials important?
In last a few decades, there has been discovery and synthesis of a new class of materials that has astonishing properties but that could not be fully explained by the laws of classical physics. These properties can only be explained by quantum mechanics.
The Border Between Classical and Quantum Worlds: When Does Physics Go Quantum?
The value of this constant is very small = 6.626 x 10−34 J⋅s. At the time, no one fully understood the significance of this extremely small constant, but later we learned that it is this constant that sets the boundary between classical and quantum mechanics. In other words, this seemingly insignificant constant, with the dimension of energy x time, determines whether we need classical physics or quantum mechanics to describe a system.

Quantum confinement effect: controlled dance of electrons at microscopic level
Every solid material is made up of atoms and atoms have electrons. The arrangement of electrons in a material determines the properties of the material. In bulk materials (when the size of the material is big enough, let’s say more than 100 nm), the electrons are free to move in all the three dimensions (similar to us, as we also live in 3D) and at this level classical physics can explain all the behaviour of the materials. However, if we reduce the size of the material to microscopic scale, where electron movement is restricted at least in once dimension, the properties of the material change dramatically
The Pauli Effect: A Nightmare for Experimental Physicists
One of the most famous stories of the Pauli effect occurred in 1950 at Princeton University. A complex device suddenly broke down for no apparent reason. Scientists at the lab later discovered that Pauli had just come into town! This incident further cemented the myth.
