论文摘要
我们报告了基于超导量子的系统中完美W-State的第一个实验实现。与最大纠缠的状态相反，完美的W状态在最大纠结W-State中包含的术语的权重和阶段不同。县长状态在量子信息处理任务中发现了重要的应用，例如完美的传送，超密集编码，秘密共享等。发电效率是通过Fidelity量化的，该效率通过执行完整的量子状态层析成像来计算。为了验证在生成状态下真正的非局部性的存在，我们通过实验进行了Mermin的不平等测试。此外，我们还使用实验生成的状态证明了量子信息的分裂和共享。
We report the first experimental realization of perfect W-state in a superconducting qubit based system. In contrast to maximally entangled state, the perfect W state is different in weights and phases of the terms contained in the maximally entangled W-state. The prefect W state finds important applications in quantum information processing tasks such as perfect teleportation, superdense coding, secret sharing etc. The efficiency of generation is quantified by fidelity which is calculated by performing full quantum state tomography. To verify the presence of genuine nonlocality in the generated state, we experimentally perform Mermin's inequality tests. Further, we have also demonstrated splitting and sharing of quantum information using the experimentally generated state.
