Theory of the coherent decay of high-lying Rydberg states in beam-foil encounters

Tamar Seideman, Moshe Shapiro, Z. Vager

Theory for the generation and decay of high-lying Rydberg states in beam-foil experiments is presented. Our theory is designed to check the assumption that electron capture in the foil proceeds via a direct transition from a free state. The success of the theory in explaining the observed (primary and secondary) oscillatory structure and underlying smooth background of the ionization signal, as a function of additional variable electric fields, justifies this assumption. In addition, existence of asymmetry with respect to sign change of the variable fields is predicted to be detectable at high field values. Generation of Rydberg atoms in beam-foil experiments is shown to be a sensitive probe of the state distribution prepared during the beam's passage through the foil. Our theory substantiates the claim that Rydberg atoms produced in the beam-foil encounter exit the foil in a pure superposition state.

Remote Stimulated Triggering of Quantum Entangled Nuclear Metastable States of 115mIn

Daniel L. Van Gent

We report experiments in which two indium foils were quantum entangled via photoexcitation of stable 115In to radioactive 115mIn by utilizing Bremsstrahlung gamma photons produced by a Varian Compact Linear Accelerator (CLINAC). After photo-excitation, remote triggering of the "master" foil with low energy gamma photons, yielded stimulated emissions of 336 keV gamma photons from quantum entangled 115mIn in the "slave" foil located up to 1600 m away from the "master" foil. These experiments strongly demonstrate that useful quantum information can be transferred through quantum channels via modulation of quantum noise (accelerated radioactive decay of 115mIn metastable nuclei). Thus, this modality of QE transmission is fundamentally different from optical QE information transfer via quantum entangled space "q-bits" as developed by information theorists for quantum channel information transfer. Additionally, there is no obvious potential for signal degradation with increasing distance nor the problems associated with misalignment of optical information transfer systems.
