ABSTRACT
The adiabatic criterion is a key requirement for the successful implementation of adiabatic quantum computing and other adiabatic processes. However, in interacting many-body systems, energy gaps often decrease quickly with the number of qubits, resulting in the violation of the adiabatic criterion and the occurrence of diabatic transition to excited states. Here I present an approach to enhance quantum adiabaticity in adiabatic processes that does not require a priori spectral knowledge of a quantum system or the construction of unphysical many-body interactions. We will demonstrate this approach with numerical simulation.
