Nonlinear optics revolutionized the ability to create directed, laser-like light particularly in the regions
where lasers based on conventional population inversion are not practical. New breakthroughs in
attosecond extreme nonlinear optics promise a similar revolution in the X-ray regime. In this talk, I will
discuss the fundamental quantum physics and the phase matching limits of high order harmonic generation
in the context of designing coherent X-ray waveforms in the soft X-ray region which can be tailored in the
moment of generation. Such a versatile light source is ideal for 4D studies of various bio- and nanosystems with attosecond temporal and nanometer spatial resolution, as well as with element and chemical
specificity. I will also discuss the path forward for generating bright coherent X-ray beams from a
laboratory-scale apparatus at photon energies of 10 keV and greater with unprecedented attosecond-tozeptosecond pulse durations, and with arbitrary spectral, temporal shapes, and spin and orbital angular
momentum. A fully spatially and temporally coherent version of the Roentgen X-ray tube with exquisite
quantum control of the properties of the soft and hard X-ray light may be possible
