Quantum Trajectories

Wavefunctions of quantum systems evolve deterministically according to Schrödinger’s equation. Add observation to the mix, and the evolution of the wave function becomes erratic. We will turn on the observation of a superconducting quantum system with a precise dial, and observe the cross-over between the two regimes.
