Mapping the optimal route between two quantum states

Experiment measures millions of quantum trajectories to predict ‘most likely’ route

As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory. For each start and end state there is an optimal or “most likely” path, but it is not as easy to predict the path or track it experimentally as a straight-line between two points would be in our everyday, classical world.
