The perturbation theory is developed based on small parameters which naturally appear in solid state quantum computation. We report the. In addition, multiple uses of (higher-order) perturbation theory lead to Hamiltonians with undesirable qubit overhead and complexity. Consequently, existing models of Hamiltonian quantum computation based on pairwise qubit interactions are not particularly suitable for physical implementation using, e.g., solid-state quantum information processors.

In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a mathematical solution is known, and add an additional "perturbing" Hamiltonian representing a weak disturbance to the system. class of problems related to quantum information theory, including aspects of clas-sical and quantum cryptography, as well as the computational complexity theory and quantum algorithms. On the another hand, when it comes to the realization of quantum computers in the applications of topological theory . Resonant Perturbation Theory of Decoherence and Relaxation of Quantum Bits M.

A bit unusual for a physics book, but that's their style. The rest of the book deals with the usual and other material: zero-temperature Green's functions and perturbation theory (for energy, Green's function, etc.) The treatment is detailed and relatively exhaustive. Then there is Reviews:
