Hamiltonian Dynamics

Definition

Hamiltonian dynamics is a formulation of classical mechanics that describes the evolution of a physical system over time using Hamilton's equations. This framework is pivotal in understanding how energy, especially in the context of quantum systems like superconducting qubits, influences the behavior and interactions of particles. It provides a clear connection between classical and quantum mechanics, allowing for the study of energy states and transitions critical to the functioning of quantum computing technologies.
