Authors: E. Torrontegui, D. Heinrich, M. I. Hussain, R. Blatt, and J. J. Garc\'ia-Ripoll
Abstract summary: We propose a new protocol to implement ultra-fast two-qubit phase gates with trapped ions using spin-dependent kicks induced by resonant transitions. Such gates allow us to increase the number of gate operations that can be completed within the coherence time of the ion-qubits.

Abstract: 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.

parallel operations are important for both near-term quantum computers and larger-scale fault-tolerant machines. We propose and implement a pairwise-parallel gate scheme on a trapped-ion quantum computer. We demonstrate the utility of this scheme by creating a GHZ state in one step using parallel gates with one overlapping qubit.

We present a quantum optimal control framework for implementing fast entangling gates on ion-trap quantum processors. The framework leverages tailored laser pulses to drive the multiple vibrational sidebands of the ions to create phonon-mediated entangling gates. Our approach represents a step in speeding up quantum gates to achieve larger quantum circuits for quantum computation and simulation.

Microwave-activated gates between a fluxonium and a transmon qubit [59.95978973946985]
We propose and analyze two types of microwave-activated gates between a fluxonium and a transmon qubit. For a medium-frequency fluxonium qubit, the transmon-fluxonium system allows for a cross-resonance effect mediated by the higher levels of the fluxonium. A fast microwave CPHASE gate can be implemented using the higher levels of the fluxonium.

Proposal for entangling gates on fluxonium qubits via a two-photon transition [0.0]
We propose a family of microwave-activated entangling gates on two capacitively coupled fluxonium qubits. A microwave pulse applied to either qubit induces two-photon Rabi oscillations with a negligible leakage outside the computational subspace. Our gate scheme is promising for large-scale quantum processors.

We find that achievable gate fidelity is independent of the number of ions in the chain. We find that population transfer efficiencies of above $99.9%$ from individual ultra-fast pulses is the threshold for realising high-fidelity gates.
