My current interest is in Quantum entanglement and relativity. Nonlocality is ubiquitous yet we never see superluminal communication? How and why does Quantum mechanics know about relativity?!<br>

<h5>Simulation of two-level quantum system using classical coupled oscillators</h5>
<divclass="eventDetail">
<p> Two-level quantum systems are arguably the simplest non-trivial quantum systems and they are said to deviate most
dramatically from classical systems. However, there have been instances of demonstration of classical analogues of
two-level quantum systems. In this report, the mathematical analogy between the Schrodinger equation of a two level
quantum system and the classical equations governing the motion of a coupled oscillator is explored. The results are
compared with the dynamics of a two level quantum system, specifically a two level atom interacting with a monochromatic
light field. Classical analogy between dressed states of coherent atom-laser interaction and the normal mode frequencies
of a classical coupled oscillator has been explored previously. Related phenomena, like electromagnetically induced
transparency (EIT) and double EIT have been demonstrated in coupled electrical resonator circuits.<br>

<h5>Affordable Small Radio Telescope</h5>
<divclass="eventDetail">
<p> During this project, I got the first proper exposure to paradoxes in quantum mechanics and how to visualize states on a Mach Zender
intereferrometer. I began with doing basic experiments on a Mach Zender
interferrometer like double slit interference, diffraction, etc. and went on to
see transitions in Rubidium atoms induced by optical beats. Every phenomena I encountered motivated me to question how it is different from that of classical waves or particles, which elucidated the probabilistic interpretation of quantum mechanics. My mentor wanted me
to learn everything(experimentally and theoretically) and so even the photodetectors that I used were made from scratch ! I studied in detail how energy conservation, superposition principle and uncertainty principle can be observed in an interferrometer.
The phenomena of optical beats was quite interesting, where I used an Acoustic Optic Modulator to shift the frequency of a part of the
original beam by a small amount(80 Mhz) and then made it interfere with the original. As a result of this, the resultant intensity goes up and down similar to beats phenomena in sound(same way as we hear beats when two flute players with a small difference in scales

As the name suggests, the cost of the radio telescope is minimal and it is designed such that it can be replicated by anyone and everyone. The cost of building has been kept low by using off the shelf equipment which is easily available anywhere in the world.

<pstyle="text-align:left"> In a seminal paper, Meyer [David Meyer, Phys. Rev. Lett. 82, 1052 (1999)] described the advantages of quantum game theory by looking at the classical penny flip game. A player using quantum strategy can win against a classical player almost 100\% of the time. Here we make a slight modification of the quantum game, with the two players sharing an entangled state to begin
with. We then analyze two different scenarios, first in which quantum player makes unitary transformations to his qubit while the classical player uses a
pure strategy of either flipping or not flipping the state of his qubit. In this case the quantum player always wins against the classical player. In the second scenario we have the quantum player making similar unitary transformations while the classical player makes use of a mixed strategy wherein he either flips or not with some probability ``p''. We show that in the second scenario, 100\% win record of a quantum player is drastically reduced and for a particular probability ``p'' the classical player can even win against the quantum player. This is of possible relevance to the field of quantum computation as we show that in this quantum game of preserving versus destroying entanglement a particular classical algorithm can beat the quantum algorithm. <br>
