      abstract     = {Here, we use x-rays to create and probe quantum coherence
                      in the photoionized amino acid glycine. The outgoing
                      photoelectron leaves behind the cation in a coherent
                      superposition of quantum mechanical eigenstates. Delayed
                      x-ray pulses track the induced coherence through resonant
                      x-ray absorption that induces Auger decay and by
                      photoelectron emission from sequential double
                      photoionization. Sinusoidal temporal modulation of the
                      detected signal at early times (0-25 fs) is observed in both
                      measurements. Advanced ab initio many-electron simulations
                      allow us to explain the first 25 fs of the detected coherent
                      quantum evolution in terms of the electronic coherence. In
                      the kinematically complete x-ray absorption measurement we
                      monitor its dynamics for a period of 175 fs and observe an
                      evolving modulation that may implicate the coupling of
                      electronic to vibronic coherence at longer time scales. Our
                      experiment provides a direct support for the existence of
                      long-lived electronic coherence in photoionized
                      biomolecules.},
