研究目的
To generate stable multiparticle entanglement in a solid-state setup using an array of silicon-vacancy centers embedded in a quasi-one-dimensional acoustic diamond waveguide.
研究成果
The proposed scheme efficiently generates stable multiparticle entanglement in a solid-state system using SiV centers in a diamond waveguide. By controlling the distance between centers to exploit destructive interference, a Dicke superradiance model is realized, leading to high-fidelity entangled states. This approach offers a feasible platform for quantum information processing with spins and phonons in solid-state systems.
研究不足
The scheme requires precise positioning of SiV centers to achieve destructive interference of dipole-dipole interactions. The quality of entanglement may be affected by environmental noise and decoherence effects.
1：Experimental Design and Method Selection:
The scheme involves embedding an array of silicon-vacancy (SiV) centers in a quasi-one-dimensional acoustic diamond waveguide to induce controllable dissipative coupling among the SiV centers. The dipole-dipole interactions are switched off due to destructive interference by appropriately choosing the distance between the SiV centers, realizing a Dicke superradiance model.
2：Sample Selection and Data Sources:
The samples are arrays of SiV centers in a diamond waveguide. The data sources are the interactions between the SiV centers and the phonon modes in the waveguide.
3：List of Experimental Equipment and Materials:
The setup includes a diamond waveguide and an array of SiV centers. The material properties of the diamond waveguide are specified (e.g., density, Young’s modulus, Poisson ratio).
4：Experimental Procedures and Operational Workflow:
The procedure involves positioning SiV centers at specific distances to achieve destructive interference of dipole-dipole interactions, coupling the centers to phonon modes, and driving the system to a steady state of entanglement.
5：Data Analysis Methods:
The degree of entanglement is quantified using spin squeezing parameters, and the system's dynamics are analyzed using the Born-Markovian master equation.
