Abstract
Shortcuts to adiabaticity (STA) are channels that can fast prepare a desired quantum state with high fidelity which obtains more and more research in the atomic domain. Based on stimulated Raman shortcut-to-adiabatic passage (STIRSAP), we propose a frequency conversion technique which works through a non-adiabatic route and produces the same energy distribution as in adiabatic evolution. Numerical simulation results show that the conversion is efficient and robust. Our results reveal a novel scenario for frequency conversion and relax the strict limitations on system parameters in adiabatic frequency conversion.
