Quantum Is Here: A Century of Quantum Science and the Rise of Quantum Information in Chicago
Overview
The talk presents a century long narrative of quantum physics, connecting classical ideas about motion to modern quantum information science. Delivered at the Royal Institution, the speaker links historical experiments to current technologies and highlights the role of Black scientists in the field and the Chicago quantum ecosystem.
He explores wave particle duality, the photoelectric effect, and diffraction, and includes a live demonstration of a flame test to illustrate atomic spectra. The talk also outlines how qubits, quantum networks, and a quantum internet may transform computation, communication, and security, while detailing the IBM HBCU Quantum Center and broader global investment in quantum technologies.
Introduction and Quantum Foundations
The speaker begins by framing quantum science as the culmination of a long history in physics, comparing physics to other disciplines where foundational subjects give way to more advanced topics. He emphasizes the transformation from classical motion to quantum phenomena, noting that quantum ideas have been with us for a hundred years and continue to shape technology today.
Key themes include energy, force, displacement, and the evolution from classical laws to quantum descriptions. The talk introduces wave–particle duality, the uncertainty principle, and the challenge of reconciling classical intuition with quantum reality, including how light can behave as both a wave and a stream of photons, as first argued in historical diffraction experiments and refined by later work on the photoelectric effect.
