A Glimpse Into the Quantum World

Lecture Hall, Science Gallery Bengaluru (At SGB) View Directions Arvind How did the quantum world change our understanding of reality and lead to quantum computing? The talk will begin with the "First Quantum Revolution" at the dawn of the 20th century, marking the birth of quantum mechanics and a profound departure from classical reality. Key counterintuitive concepts—superposition, measurement, and entanglement—will be introduced, alongside Einstein's foundational critique (the EPR paradox), Bell's inequalities, experimental Bell violations, and the 2022 Nobel Prize in Physics. The discussion will also examine the revolutionary technologies enabled by quantum theory, including semiconductors, lasers, and superconductors. Finally, the talk explores the latest quantum revolution born from merging quantum physics with information theory, highlighting ongoing breakthroughs in quantum computing, quantum communication, and quantum metrology.
