Fascinating world of photons, superposition and entanglement
ABSTRACT :
Quantum mechanics is a cornerstone of modern physics. Just as the 19th century was called the Machine Age and the 20th century the Information Age, the 21st century promises to go down in history as the Quantum Age. In this talk, I will discuss key properties of quantum systems called Quantum Superposition and Quantum Entanglement. I will discuss the world of single and entangled photons and also discuss ongoing work towards quantum technology in our Quantum Information and Computing lab at the Raman Research Institute, Bengaluru.
ABOUT THE SPEAKER:
Urbasi Sinha is an associate professor at the Light and Matter Physics group at the Raman Research Institute in Bangalore, India. She joined RRI in 2012 and is now heading the Quantum Information and Computing (QuIC) laboratory at RRI. The lab specializes in experiments on quantum information processing including quantum computing and quantum communication, primarily using single and entangled photons. She is also an associate faculty member at the Institute for Quantum Computing (IQC), University of Waterloo, Canada, and the Centre for Quantum Information and Quantum Control, University of Toronto, Canada. Before joining RRI, Urbasi was a post-doctoral fellow at IQC. She was involved in Quantum Optics based experiments involving production, manipulation and application of heralded single photons as well as device fabrication for solid state quantum devices based on nanowires and carbon nanotubes. One of her noted pieces of work was a novel experimental test of the Born rule for probabilities in Quantum Mechanics.
Prior to her post-doctoral stint at IQC, Urbasi was a post-doctoral research associate in the Cavendish labs, Department of Physics, University of Cambridge, UK. She completed her PhD in Cambridge on experiments in high TC Superconductivity. She completed her M.Sc in Physics also from Cambridge. She has been a Gates Cambridge scholar during her Ph.D and a Nehru-Chevening scholar during her masters.
During her time in Cambridge, Urbasi developed skills in thin film deposition and device fabrication using lithography, etching, milling and sputtering as well as electrical and magnetic characterization of devices. Her projects there involved a combination of theory and experiment and got her interested in multidisciplinary problems. In recognition of her scientific achievements as well as outreach activities, she was awarded the Homi Bhabha Fellowship in the year 2017 and has has most recently been named the recipient of the 2018 ICTP-ICO Gallieno Denardo Award in Optics.
