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…
Witnessing spin-orbit thermal entanglement in rare-earth ions
O. S. Duarte, C. S. Castro, D. O. Soares-Pinto +1
We explore spin-orbit thermal entanglement in rare-earth ions, based on a witness obtained from mean energies. The entanglement temperature , below which entanglement emerge…
