Schrödinger lecture 2014: Professor Serge Haroche Shedding new light on Schrödingers cat

Quantum theory has allowed scientists to understand better the subatomic world, and led to revolutionary technologies including computers, lasers and atomic clocks. In spite of its successes, quantum physics can seem strange and counterintuitive. It describes a world in which the concepts of waves and particles are deeply intertwined; and has led to the bizarre notions of superposition, which allows particles to exist in many concurrent states until observed, and entanglement, whereby particles control the
