“…This technique has gained theoretical and experimental studies in atomic and molecular [21] and superconducting quantum systems [22]. When TQD is applied to speed up the adiabatic operation in three-level quantum systems, the situation becomes more complicated [15,[23][24][25][26]. In 2010, Chen et al [15] employed the TQD to speed up adiabatic passage techniques in three-level atoms extending to the short-time domain their robustness with respect to parameter variations.…”

Three-level quantum systems, which possess some unique characteristics beyond two-level ones, such as electromagnetically induced transparency, coherent trapping, and Raman scatting, play important roles in solid-state quantum information processing. Here, we introduce an approach to implement the physically feasible threelevel transitionless quantum driving with multiple Schrödinger dynamics (MSDs). It can be used to control accurately population transfer and entanglement generation for three-level quantum systems in a nonadiabatic way. Moreover, we propose an experimentally realizable hybrid architecture, based on two nitrogen-vacancycenter ensembles coupled to a transmission line resonator, to realize our transitionless scheme which requires fewer physical resources and simple procedures, and it is more robust against environmental noises and control parameter variations than conventional adiabatic passage techniques. All these features inspire the further application of MSDs on robust quantum information processing in experiment.

“…Hence one can see that, a large ∆ p does provide an immune way to the spontaneous emission of atom. The technology of shortcut to adiabatic passage permits a fast manipulation of quantum states in a robust way against the fluctuation of parameters [34][35][36][37][38]. In order to design a counteradiabatic Hamiltonian that can be realized in experiment, we first consider a toy model below…”

We propose a mechanism of ground-state blockade between two N -type Rydberg atoms in virtue of Rydbergantiblockade effect and Raman transition. Inspired by the quantum Zeno effect, the strong Rydberg antiblockade interaction plays a role in frequently measuring one ground state of two, leading to a blockade effect for double occupation of the corresponding quantum state. By encoding the logic qubits into the ground states, we efficiently avoid the spontaneous emission of the excited Rydberg state, and maintain the nonlinear RydbergRydberg interaction at the same time. As applications, we discuss in detail the feasibility of preparing two-atom and three-atom entanglement with ground-state blockade in closed system and open system, respectively, which shows that a high fidelity of entangled state can be obtained with current experimental parameters.

“…Entanglement is a key resource in quantum information processing [1], which has been intensively investigated in microscopic systems, such as cavity-QED [2][3][4][5][6]. Macroscopic entanglement is a research field full of curiosity, and quantum optomechanical system is now considered to be useful for its investigation [7][8][9][10][11][12][13][14].…”

Stationary entanglement in a four-mode optomechanical system, especially under roomtemperature, is discussed. In this scheme, when the coupling strengths between the two target modes and the mechanical resonator are equal, the results cannot be explained by the Bogoliubovmode-based scheme. This is related to the idea of quantum-mechanics-free subspace, which plays an important role when the thermal noise of the mechanical modes is considered. Significantly prominent steady-state entanglement can be available under room-temperature.
