Adiabatic Quantum Computation, while attractive due to its "hands-off" approach and intrinsic tolerance of noise, has not been shown to be fully fault-tolerant in a satisfying manner. The protection of the evolution from noise and decoherence through the use of an energy penalty, recently proposed as a method to suppress error in adiabatic algorithms, is also appealing due to its passiveness. In this thesis, we first introduce the background on quantum computation, and discuss existing efforts towards fault-tolerant computation, specifically in the adiabatic model. Subsequently, we will prove a general result concerning the utility of energy-gap protection in generic (not necessarily adiabatic) quantum evolution in open system, and provides analytic bounds on the necessary energy penalty magnitude to achieve good protection. Evidence from numerical simulation is also given to demonstrate the practical usefulness of energy-gap protection for fault-tolerant quantum computation in open systems. by Xiang-Yu (Leo) Zhou.
