Delayed Choice Quantum Coherent Control    [PDF]

Torsten Scholak, Paul Brumer
A Bell test for a particular implementation of coherent control is shown to certify the quantumness of that scenario. Specifically, a multi-photon ionization experiment with alkali atoms is devised to demonstrate the analogy between coherent control and single-photon interference in a Young double-slit. We describe two complementary experimental situations, which are characterized by a random photoelectron spin polarization with particle-like behavior on the one hand, and by spin controllability and wave-like nature on the other. The simultaneous realization of both situations naturally leads to an implementation of quantum delayed choice.
