Symmetry-Protected Quantum Computing using Metamaterials
Neil F. Johnson, Ferney J. Rodriguez, Luis Quiroga
We propose a new architecture for practical quantum computing that combines three established principles: symmetry protection of relative-motion qubits via the generalized Kohn the…
Twisted light generates robust many-body states for practical quantum computing
Ferney J. Rodriguez, Luis Quiroga, Neil F. Johnson
Twisted light carries orbital angular momentum (OAM) and can drive excitations of confined, interacting electrons that are dark to uniform dipolar probes. Here we show how this ``b…
Twisted light drives chiral excitations of interacting electrons in nanostructures with magnetic field
F. J. Rodríguez, L. Quiroga, N. F. Johnson
Twisted light (TL), a special kind of light carrying orbital angular momentum, provides a powerful tool for driving symmetry resolved transitions in quantum confined nanostructures…
Cavity Control of Topological Qubits: Fusion Rule, Anyon Braiding, and Majorana-Schrödinger Cat States
Luis Quiroga, Fernando J. Gómez-Ruiz, Ivan A. Bocanegra-Garay +2
We investigate the effects of coupling a local electromagnetic cavity to a segment of a topological Kitaev chain (KC), with particular emphasis on the interplay between photons and…
Cavity-induced switching between Bell-state textures in a quantum dot
S. S. Beltrán-Romero, F. J. Rodríguez, L. Quiroga +1
Nanoscale quantum dots in microwave cavities can be used as a laboratory for exploring electron-electron interactions and their spin in the presence of quantized light and a magnet…
From edge to bulk: Cavity induced displacement of topological non-local qubits
F. P. M. Méndez-Córdoba, F. J. Rodríguez, C. Tejedor +1
We investigate the ability of selective cavity coupling to a topological chain for tailoring the connectivity of Majorana fermions. We show how topological qubits (TQs), associated…
Experimental validation of the Kibble-Zurek Mechanism on a Digital Quantum Computer
Santiago Higuera-Quintero, Ferney J. Rodríguez, Luis Quiroga +1
The Kibble-Zurek mechanism (KZM) captures the essential physics of nonequilibrium quantum phase transitions with symmetry breaking. KZM predicts a universal scaling power law for t…
Quantum Phase Transitions detected by a local probe using Time Correlations and Violations of Leggett-Garg Inequalities
F. J. Gómez-Ruiz, J. J. Mendoza-Arenas, F. J. Rodríguez +2
In the present paper we introduce a way of identifying quantum phase transitions of many-body systems by means of local time correlations and Leggett-Garg inequalities. This proced…
