Program | Quantum technology and quantum control with optimally tailored ultrashort laser pulses are revolutionizing molecular spectroscopy. For instance, they allowed not only observing with unprecedented detail the atomic motion within molecules but also controlling it using quantum interferences. After introducing some basic concepts about quantum pathways interference, we will concentrate on its application for discriminating signals from biological molecules that exhibit almost identical linear absorption and fluorescence spectra. In particular, quantum discrimination between amino acids allows for selectively identifying proteins in blood serum, like antibodies (Immunoglobulins G and M) and albumin. This disruptive approach was called “Quantum Controlled based Bio-assays”. The second part of the presentation will be dedicated to the vision process. We showed very recently that photo-isomerization of the retinal rhodopsin in live animals can be manipulated by quantum control procedures and thus that the vision process is sensitive to the spectral phase, unlike the usually adopted physiological concepts. Finally, we will show some preliminary experiments that open the possibility of directly seeing entanglement with the bare eye. |
