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,…
