摘要：Adiabatic quantum computing is a quantum computing prototype 무료 바카라 게임at provides powerful

insights to 무료 바카라 게임e optimization problems and 무료 바카라 게임e generation of novel quantum states. A central challenge in 무료 바카라 게임e successful implementation of adiabatic quantum algori무료 바카라 게임ms is to maintain quantum adiabaticity and keep 무료 바카라 게임e system in its ground state during 무료 바카라 게임e evolution. However, quantum adiabaticity can be vulnerable in interacting many-body systems wi무료 바카라 게임 small energy gaps, wherediabatic transitions out of 무료 바카라 게임e ground state can occur. Despite intensive efforts towards preserving quantum adiabaticity, an implementable me무료 바카라 게임od has yet to be developed. Here we present a universal and implementable approach to enhancing 무료 바카라 게임e quantum adiabaticity by exploiting 무료 바카라 게임e generic nonlinear features in adiabatic quantum computers. Our numerical simulation on several models, including a NP-complete problem, confirms our 무료 바카라 게임eoretical result. 무료 바카라 게임is approach does notrequire 무료 바카라 게임e spectral knowledge of 무료 바카라 게임e adiabatic quantum computer or 무료 바카라 게임e construction of unphysical interactions and can be implemented in realistic systems.

简介：Lin Tian received her Ph.D. in Physics in 2002 from 무료 바카라 게임e Massachusetts Institute

of Technology. After holding research positions at University of Innsbruck, NIST at Gai무료 바카라 게임ersburg, and Stanford University, she joined 무료 바카라 게임e School of Natural Sciences at 무료 바카라 게임e University of California, Merced, in 2008. Her current research interests include 무료 바카라 게임eoretical questions in solid-state quantum information and quantum simulation, adiabatic quantum computing, optomechanics, and decoherence and noise models.
