“…Therefore, it is necessary to find a method that combines the advantages of resonant pulses and adiabatic passage. Recently, a new technique called “shortcuts to adiabatic passages” (STAP) [ 51–72 ] is proposed. Due to the appealing benefits, STAP has been widely applied in fast quantum information processing field.…”

W states play an important role in quantum information processing and quantum computing. Here, it proposes a scheme for preparing W states by designing the evolution operators with Rydberg superatoms. It encodes quantum information on the effective energy level of the superatom, and construct shortcuts to adiabatic passages (STAP) by designing the evolution operators. Combined with Quantum Zeno dynamics and STAP, it can prepare three‐particle W states quickly and efficiently. In addition, the Rabi frequency in this scheme can be described as a linear superposition of Gaussian functions, which reduces the difficulty of practical experiment. The numerical simulation shows that the scheme is robust against decoherence, operational imperfection, and noise. At last, it generalizes this scheme to preparation of N‐particle W states.

“…[ 14 ] There have been some schemes proposed for preparing high‐dimensional entanglement by using various techniques. [ 15–28 ] With the advances in quantum computing, the entanglement can be used in quantum computing to reduce the communication complexity between different parts of the quantum computer, to realize the redundant coding without copy, and to perform the error diagnosis without destroying the coding state, etc. Therefore, the faithful entanglement gates contributes greatly to the realization of a quantum computer.…”

By using the counterdiabatic driving method, two‐atom 3D entanglement gates are constructed rapidly based on adiabatic geometric quantum computation (AGQC). The added counterdiabatic Hamiltonian does not introduce additional unaccessible ground‐state coupling, and the shapes and phases of the initial adiabatic classical‐field pulse only need to be modified. By using the optimal control technology, the effect of the control errors of Rabi frequency or detuning is suppressed effectively. Quite specially, with an appropriate choice of optimized parameters, the authors' scheme could be insensitive to these two kinds of errors simultaneously. By combining AGQC with optimal control, the scheme could offer a promising means for constructing fast and robust high‐dimensional quantum entanglement gate.
