About the Talk
Quantum computing is an emerging area that explores how the laws of quantum mechanics can be used for information processing. Unlike classical computers, which use bits that take values 0 or 1, quantum systems can exist in superpositions of states and exhibit correlations known as entanglement. These features suggest new ways of performing certain computational tasks.

The idea of quantum computing was motivated by a simple question raised by Richard Feynman: if nature itself follows quantum mechanical laws, can computers based on those same laws simulate physical systems more efficiently than classical machines?

In this introductory talk, we will discuss the basic ideas of quantum computing and the mathematical framework for describing quantum information. We will look at concepts such as qubits, superposition, and measurement, and briefly discuss some well-known quantum algorithms, including Deutsch–Jozsa, Grover’s search algorithm, and Shor’s factoring algorithm. We will also discuss the current state of quantum hardware and the challenges involved in building practical quantum computers.

The aim of the talk is to provide an accessible overview of the key ideas behind quantum computing and to give a glimpse of why this field has attracted so much interest in recent years.
