Precise control of quantum states with extreme ultraviolet lasers
An international research team, led by Dr. Lukas Bruder from the Institute of Physics at the University of Freiburg, has successfully produced and directly controlled hybrid quantum states of electrons and photons in helium atoms. Utilizing the FERMI free electron laser in Trieste, Italy, they generated highly intense extreme ultraviolet (EUV) light pulses and applied a novel laser pulse-shaping
