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 $T<2\pi/\omega$. 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.

使用谐振脉冲序列的超快双量子位离子门

我们提出了一种新协议，使用由共振跃迁引起的自旋相关踢来实现具有俘获离子的超快双量子位相位门。通过仅优化脉冲序列序列中到达时间的分配，门的实现速度比捕获振荡周期 $T<2\pi/\omega$ 快。这样的门允许我们增加可以在离子量子位的相干时间内完成的门操作的数量，有利于可扩展量子计算机的发展。
