Professor M does Science | 2-state quantum systems: energy eigenstates @ProfessorMdoesScience | Uploaded October 2023 | Updated October 2024, 12 minutes ago.
๐ป Book a 1:1 session: docs.google.com/forms/d/e/1FAIpQLScUL187erItvC7GPnNU2pelsueyVFr94nRq2A5Eq2aVRdGiIQ/viewform?pli=1
๐ 2-state quantum systems are key to understand phenomena ranging from the spin angular momentum of electrons and protons to the qubits of quantum computers. In this video, we calculate the energy eigenstates of a 2-state quantum system.
