"photon emission direction relative to remaining bound electron in cleaved neutral hydrogen atom can be controlled by time interval between 2 laser flashes on scale of few hundred attoseconds... >100,000X faster entangled quantum state control, from nanoseconds to femto- or even attoseconds... electrons' emission direction with respect to protons can be modified by delaying attosecond pulses with respect to maxima and minima of laser light on time-scale of <1 femtosecond"
