SEMINAR
Speaker: Mr. Debasish Mondal
Title: “An Introduction to Quantum Computing”
Date & Time: February 14, 2019 at 4.00 p.m
Venue: SSCU AUDITORIUM
Abstract:
The invention of the classical computer transformed human development. Today’s classical computers are capable of solving the most complex of problems and could
even challenge humans in games such as Go and Chess. However, these best of class classical computers use orders of magnitude larger power when compared to a
human brain, which is estimated to use about 20 W of power. Quantum computing as a computational approach was proposed to be more efficient than classical
computing, especially for complex computational tasks. In this talk, I will discuss the fundamental differences between classical and quantum computing; and
introduce quantum logic gates while contrasting them with classical gates. I will also discuss the approaches for building quantum circuits and outline the steps
for performing logic operations using quantum circuits. Thereafter, I will discuss the implementation of two important quantum algorithms: the Grover’s algorithm
and the Shor’s algorithm and reason out the necessity for quantum-computing approaches for solving such complex tasks. Finally, I will touch upon the
difficulties in building a physical quantum computer and briefly mention the recent progress in this field.
