Observation of environment-induced double sudden transitions in geometric quantum correlations
F. M. Paula, I. A. Silva, J. D. Montealegre +8
Correlations in quantum systems exhibit a rich phenomenology under the effect of various sources of noise. We investigate theoretically and experimentally the dynamics of quantum c…
Quantum discord determines the interferometric power of quantum states
Davide Girolami, Alexandre M. Souza, Vittorio Giovannetti +6
Quantum metrology exploits quantum mechanical laws to improve the precision in estimating technologically relevant parameters such as phase, frequency, or magnetic fields. Probe st…
Experimental Demonstration of non-Markovian Dynamics via a Temporal Bell-like Inequality
A. M. Souza, J. Li, D. O. Soares-Pinto +5
We assess non-Markovianity of a quantum open-system dynamics through the violation of temporal bell-like inequalities in a controllable Nuclear Magnetic Resonance system. We invest…
Experimental reconstruction of work distribution and verification of fluctuation relations at the full quantum level
Tiago Batalhão, Alexandre M. Souza, Laura Mazzola +6
Research on the out-of-equilibrium dynamics of quantum systems has so far produced important statements on the thermodynamics of small systems undergoing quantum mechanical evoluti…
Protected quantum computing: Interleaving gate operations with dynamical decoupling sequences
Jingfu Zhang, Alexandre M. Souza, Frederico Dias Brandao +1
Implementing precise operations on quantum systems is one of the biggest challenges for building quantum devices in a noisy environment. Dynamical decoupling (DD) attenuates the de…
