Ultrafast twoqubit ion gate using sequences of resonant pulses
Abstract
We propose a new protocol to implement ultrafast twoqubit phase gates with trapped ions using spindependent 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 ionqubits favoring the development of scalable quantum computers.
