“…However, the adiabatic condition requires long operation time, making the STIRAP inefficient when dissipation and decoherence effects are taken into consideration. Recently, an increasing interest has been devoted to accelerate the adiabatic process without losing the robustness property, such as, counterdiabatic driving [27][28][29], invariant-based inverse engineering [30][31][32], dressed-state-based shortcuts [33][34][35]. One can then drive a quantum system from a given initial state to a prescribed final state in a shorter time than adiabatic process.…”

In this paper, we propose a scheme to achieve selective population transfer in a Λ-type three-level atomic system with a train of periodical Gaussian pulses. Based on temporal constructive quantum interference between the sequential transitions and subsequent coherent accumulation, the selective population transfer can be achieved with the pulse train, without satisfying the requirement of two-photon resonance condition. It can be understood as a result of the formation of a comb-like structure of the pulse train spectrum in time domain. Numerical simulations demonstrate that the scheme is robust against the wave-form deformation of single pulse while sensitive to the pulse train repetition period. Due to the Gaussian waveform of the laser ﬁeld been readily implemented in experiments, the scheme holds great practicality for for quantum state engineering in quantum information processing.

“…Moreover, one can manipulate atoms with classical fields readily . In recent year, the development of the technique of shortcuts in adiabaticity (STA), have greatly promoted pulse design for fast and robust control of atoms in cavity QED systems. Combining the advances of cavity QED systems and STA, many protocols have been put forward to realize the preparations of atomic entangled states, which have all shown strong power of STA.…”

Here, a protocol for robust preparation of an atomic concatenated Greenberger-Horne-Zeilinger (C-GHZ) state via shortcuts to adiabaticity (STA) is proposed. The devices for implementing the protocol consist of atoms, cavities, and the optical fibers, which are feasible with current technology. The atoms are trapped in the separated cavities allowing individual control over each atom with classical fields. STA helps to design Rabi frequencies of classical fields so that the atoms can be driven from the initial states to the target states. The numerical simulations show that the protocol holds robustness against atomic spontaneous emissions and photonic leakages. Thus, the protocol may be realized by experiments in the near future.been proposed to prepare the GHZ states with different systems. For example, Zheng [21] has proposed a protocol to generate GHZ states with atoms. Wu et al. [23] have used the superconducting qubits to generate GHZ states.The protocols [21][22][23] for preparing the GHZ states mentioned above focus on the GHZ states encoded in the physical qubits directly. Recently, Fröwis and Dür [24,25] have suggested a new type of entangled states named concatenated Greenberger-Horne-Zeilinger (C-GHZ) states, which are the GHZ-like states encoded in the qubits formed by the traditional GHZ states. More specifically, the C-GHZ states can be written as DenotationState of system Denotation State of system |ψ 1 | 0, 0, 0, 0 |0 | ψ 2 | 0, 2, 0, 0 |0 |ψ 3 | 0, 1, 0, 0 |1 11l | ψ 4 | 0, 1, 0, 0 |1 f 11 |ψ 5 | 0, 1, 0, 0 |1 0l | ψ 6 | 0, 1, 1, 1 |0 |ψ 7 | 1, 0, 0, 0 |0 | ψ 8 | 1, 1, 0, 0 |0 |ψ 9 | 1, 1, 0, 0 |1 11l | ψ 10 | 1, 2, 0, 0 |1 f 11 |ψ 11 | 1, 1, 0, 0 |1 0l | ψ 12 | 2, 0, 0, 0 |0 |ψ 13 | 3, 1, 0, 0 |0
