Yan Liang, Xin Ji, Hong‐Fu Wang, Shou Zhang · Laser Physics Letters · 2015
We theoretically propose an alternative method to realize a deterministic SWAP gate using shortcuts to adiabatic passage based on the approach of Lewis-Riesenfeld invariants in cavity quantum electronic dynamics (QED). By combining Lewis-Riesenfeld invariants with quantum Zeno dynamics, the SWAP gate can be achieved deterministically. The numerical results show that our scheme presents a fast and robust approach to achieve SWAP gates.
