Engineering protected cavity-QED interactions through pulsed dynamical decoupling
I. Arrazola, P. Bertet, Y. Chu +1
We study a generic cavity QED setup under conditions where the coupling between the two-level systems and a single bosonic mode is significantly degraded by low-frequency noise. To…
Constructing the spin-1 Haldane phase on a qudit quantum processor
C. L. Edmunds, E. Rico, I. Arrazola +4
Symmetry-protected topological phases have fundamentally changed our understanding of quantum matter. An archetypal example of such a quantum phase of matter is the Haldane phase,…

I. Arrazola, Y. Minoguchi, M. -A. Lemonde +2
We analyze the implementation of high-fidelity, phonon-mediated gate operations and quantum simulation schemes for spin qubits associated with silicon vacancy centers in diamond. S…
Boson sampling with ultracold atoms in a programmable optical lattice
Carsten Robens, Iñigo Arrazola, Wolfgang Alt +4
Sampling from a quantum distribution can be exponentially hard for classical computers and yet could be performed efficiently by a noisy intermediate-scale quantum device. A prime…
Robust Two-Qubit Gates Using Pulsed Dynamical Decoupling
Patrick Barthel, Patrick H. Huber, Jorge Casanova +5
We present the experimental implementation of a two-qubit phase gate, using a radio frequency (RF) controlled trapped-ion quantum processor. The RF-driven gate is generated by a pu…

L. Cong, S. Felicetti, J. Casanova +3
We demonstrate the emergence of selective -photon interactions in the strong and ultrastrong coupling regimes of the quantum Rabi model with a Stark coupling term. In particular…
Spin-boson model as a simulator of non-Markovian multiphoton Jaynes-Cummings models
R. Puebla, G. Zicari, I. Arrazola +3
The paradigmatic spin-boson model considers a spin degree of freedom interacting with an environment typically constituted by a continuum of bosonic modes. This ubiquitous model is…
Selective Hybrid Spin Interactions with Low Radiation Power
I. Arrazola, E. Solano, J. Casanova
We present a protocol for designing appropriately extended pulses that achieves tunable, thus selective, electron-nuclear spin interactions with low-driving radiation power. Ou…
Probabilistic Eigensolver with a Trapped-Ion Quantum Processor
Jing-Ning Zhang, Iñigo Arrazola, Jorge Casanova +3
Quantum simulation of complex quantum systems and their properties often requires the ability to prepare initial states in an eigenstate of the Hamiltonian to be simulated. In addi…
