Ultra-fast two-qubit ion gate using sequences of resonant pulses.New Journal of Physics, 22, 103024.1367-2630https://hdl.handle.net/10016/32003We 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.11eng© 2020 The Author(s).Atribución 3.0 EspañaQuantum informationTrapped ionsQubit gatesresearch articleFísicahttps://doi.org/10.1088/1367-2630/abbab6open access111New Journal of Physics22AR/0000026494
