Experimental Detection of the Correlation Rényi Entropy in the Central Spin Model
Mohamad Niknam, Lea F. Santos, David G. Cory
We propose and experimentally measure an entropy that quantifies the volume of correlations among qubits. The experiment is carried out on a nearly isolated quantum system composed…

Sensitivity of quantum information to environment perturbations measured with a non-local out-of-time-order correlation function
Mohamad Niknam, Lea F. Santos, David G. Cory
In a quantum system coupled with a non-Markovian environment, quantum information may flow out of or in to the system. Measuring quantum information flow and its sensitivity to per…
