摘要:

光连接量子比特可以有效地减少退相干,促进长距离通信。光寻址自旋分子在量子计算中具有良好的应用前景。在本报告中,针对双自由基(潜在的量子计算电路单元)计算了光诱导交换相互作用和自旋动力学,这对于基于自旋的量子计算来说本质上很重要。与先前的实验观察到的光激发诱导自旋相干性一致,我们的工作证明了一种光驱动的量子门操作方案,暗示了分子量子电路网络的巨大潜力。提出了一种结合二维分子网络和可编程纳米光子学的量子线路的设计方案。因此,我们设想化学数据库的计算探索,以确定合适的候选人的分子自旋量子位和耦合器,这可能是最佳的纳米光子器件集成,实现量子线路。因此,这里提出的工作将开辟一个新的方向,探索量子技术的“点击化学”。

英文摘要:

Optically connecting quantum bits can effectively reduce decoherence and facilitate long-distance communication. Optically addressable spin-bearing molecules have been demonstrated to have a good potential for quantum computing. In this report optically induced exchange interactions and spin dynamics, which are inherently important for spin-based quantum computing, have been calculated for a bi-radical - a potential quantum computing circuit unit. Consistent with the previous experimental observation of spin coherence induced by optical excitation, our work demonstrated an optically driven quantum gate operation scheme, implying a great potential of molecular quantum-circuit network. A blueprint of quantum circuit, integrating two-dimensional molecular network and programmable nano-photonics, both of which have been under extensive investigations and rather mature, was proposed. We thus envisage computational exploration of chemical database to identify suitable candidates for molecular spin quantum bit and coupler, which could be optimally integrated with nano-photonic devices to realize quantum circuit. The work presented here would therefore open up a new direction to explore 'Click Chemistry' for quantum technology.
