论文摘要
我们提出了一种新的协议，使用谐振转变引起的自旋依赖性踢球实现超快速的两数quit相位门。通过仅优化脉冲序列序列中到达时间的分配，栅极的实现速度比捕获振荡周期$ t <2π/ω$更快。这样的门使我们能够增加可以在离子Qubits的相干时间内完成的门操作数量，从而有利于开发可扩展的量子计算机的开发。
We propose a new protocol to implement ultra-fast two-qubit phase gates with trapped ions using spin-dependent kicks induced by resonant transitions. By only optimizing the allocation of the arrival times in a pulse train sequence the gate is implemented in times faster than the trapping oscillation period $T<2π/ω$. Such gates allow us to increase the number of gate operations that can be completed within the coherence time of the ion-qubits favoring the development of scalable quantum computers.
