Experimental Implementation of a Concatenated Quantum Error-Correcting Code
Nicolas Boulant, Lorenza Viola, Evan M. Fortunato +1
Concatenated coding provides a general strategy to achieve the desired level of noise protection in quantum information storage and transmission. We report the implementation of a…
Advances in decoherence control
Lorenza Viola
I address the current status of dynamical decoupling techniques in terms of required control resources and feasibility. Based on recent advances in both improving the theoretical d…
Entanglement beyond subsystems
Lorenza Viola, Howard Barnum, Emanuel Knill +2
We present a notion of generalized entanglement which goes beyond the conventional definition based on quantum subsystems. This is accomplished by directly defining entanglement as…
Entanglement as an Observer-Dependent Concept: An Application to Quantum Phase Transitions
Gerardo Ortiz, Rolando Somma, Howard Barnum +2
This paper addresses the following main question: Do we have a theoretical understanding of entanglement applicable to a full variety of physical settings? It is clear that not onl…
Nature and Measure of Entanglement in Quantum Phase Transitions
Rolando Somma, Gerardo Ortiz, Howard Barnum +2
Characterizing and quantifying quantum correlations in states of many-particle systems is at the core of a full understanding of phase transitions in matter. In this work, we conti…
