Atomic clocks are the astir precise timepieces successful the world. Modern versions are truthful close that they whitethorn summation oregon suffer lone a 2nd implicit a play comparable to the property of the universe. At the halfway of these clocks are electrons successful circumstantial atoms that modulation betwixt defined vigor levels erstwhile they sorb oregon emit electromagnetic radiation astatine a precise frequency. The measurement of these transitions is highly analyzable and usually requires ultra-stable lasers operating successful assorted modes. In India, each components needed to physique atomic clocks, specified arsenic lasers and frequence combs, indispensable beryllium imported.
Now, a Pune-based startup, QuPrayog Priave Limited, a spin-off from the Indian Institute of Science Education and Research (IISER) Pune, aims to make precocious Titanium Sapphire Laser systems for precocious quantum exertion applications. It is among the 8 that volition beryllium supported nether the Department of Science and Technology’s National Quantum Mission.
“These clocks present person respective captious applications. For instance, they are astatine the bosom of Global Positioning Systems (GPS), and the accuracy of the atomic clocks straight affects the positioning accuracy. Other applications scope from the synchronisation of information transportation successful connection networks to the time-stamping of fiscal transactions,” Dr Sunil Nair, prof astatine the Department of Physics astatine Indian Institute of Science Education and Research, Pune, told The Indian Express.
Nair explained that a cardinal constituent is simply a frequence comb, a spectrum consisting of a bid of arsenic spaced frequence lines, akin to the teeth of a comb.
“Currently, each these parts which spell into making atomic clocks, similar lasers and frequence combs, person to beryllium imported. One of the selected startups is simply a spin-off from IISER Pune. Co-founded by Dr Rahul Sawant, a module chap astatine I-Hub QTF; and Dr Jay Mangaonkar, a postdoctoral chap astatine IISER Pune, this startup aims to make precocious Titanium Sapphire Laser systems for precocious Quantum Technology applications. These are tunable lasers which typically emit successful the reddish and near-infrared region, and are astatine the bosom of ultra-stable atomic clocks,” helium said.
Dr Nair, the task manager of I-Hub Quantum Technology Foundation, said this task promises to execute indigenous capabilities successful this strategically important sector.
In August this year, I-Hub Quantum Technologies Foundation hosted astatine IISER Pune announced a telephone for proposals for startups successful the domain of quantum technology. The ceremonial announcement of selected startups was made by Dr Jitendra Singh, Minister of State (Independent Charge) for Science and Technology and Earth Sciences, astatine a caller relation held astatine the India Habitat Centre successful New Delhi.
