Summary 
This book presents the first comprehensive treatment of discrete phasespace quantum mechanics and the lattice WeylWigner formulation of energy band dynamics, by the originator of these theoretical techniques. The author's quantum superfield theoretical formulation of nonequilibrium quantum physics is given in real time, without the awkward use of artificial time contour employed in previous formulations. These two main quantum theoretical techniques combine to yield general (including quasiparticlepairing dynamics) and exact quantum transport equations in phasespace, appropriate for nanodevices. The derivation of transport formulas in mesoscopic physics from the general quantum transport equations is also treated. Pioneering nanodevices are discussed in the light of the quantumtransport physics equations, and an indepth treatment of the physics of resonant tunneling devices is given. Operator Hilbertspace methods and quantum tomography are discussed. Discrete phasespace quantum mechanics on finite fields is treated for completeness and by virtue of its relevance to quantum computing. The phenomenological treatment of evolution superoperator and measurements is given to help clarify the general quantum transport theory. Quantum computing and information theory is covered to demonstrate the foundational aspects of discrete quantum dynamics, particularly in deriving a complete set of multiparticle entangled basis states
