我们开发了新的脉冲方案来显著加快绝热状态转移协议的速度。我们的一般策略包括对利用非绝热跃迁的初始控制哈密顿量添加校正。这些校正定义了系统在状态转移期间完全遵循的一组修饰状态。我们将这一方法应用于受激拉曼绝热传输协议，并证明了合适的装饰态的选择允许人们设计不需要额外耦合的快速协议，同时最小化“中间”能级的占用。
We develop new pulse schemes to significantly speed up adiabatic state transfer protocols. Our general strategy involves adding corrections to an initial control Hamiltonian that harness nonadiabatic transitions. These corrections define a set of dressed states that the system follows exactly during the state transfer. We apply this approach to stimulated Raman adiabatic passage protocols and show that a suitable choice of dressed states allows one to design fast protocols that do not require additional couplings, while simultaneously minimizing the occupancy of the “intermediate” level.
