Specifically, we calculate quantum deviations from the classical decay after the break time t for both broken and preserved time-reversal symmetry. The source of these corrections is identified in interfering pairs of correlated classical trajectories. In our approach the quantized chaotic system is modelled by a quantum graph.journal_article10.1209/epl/i2004-10347-6000227070200001
