Coherence orders, decoherence and quantum metrology
Diego P. Pires, Isabela A. Silva, Eduardo R. deAzevedo +2
Since the dawn of quantum theory, coherence was attributed as a key to understand the weirdness of fundamental concepts like the wave-particle duality and the Stern-Gerlach experim…
NMR Contributions to the study of Quantum Correlations
Isabela A. Silva, Jefferson G. Filgueiras, Ruben Auccaise +7
In this chapter we review the contributions of Nuclear Magnetic Resonance to the study of quantum correlations, including its capabilities to prepare initial states, generate unita…
There is more to quantum interferometry than entanglement
Thomas R. Bromley, Isabela A. Silva, Charlie O. Oncebay-Segura +4
Entanglement has long stood as one of the characteristic features of quantum mechanics, yet recent developments have emphasized the importance of quantumness beyond entanglement fo…
Observation of time-invariant coherence in a room temperature quantum simulator
Isabela A. Silva, Alexandre M. Souza, Thomas R. Bromley +9
The ability to live in coherent superpositions is a signature trait of quantum systems and constitutes an irreplaceable resource for quantum-enhanced technologies. However, decoher…
Computational speed-up in a single qudit NMR quantum information processor
I. A. Silva, B. Çakmak, G. Karpat +5
Quantum algorithms are known for presenting more efficient solutions to certain computational tasks than any corresponding classical algorithm. It has been thought that the origin…
Computational speed-up with a single qudit
Z. Gedik, I. A. Silva, B. Çakmak +5
Quantum algorithms are known for providing more efficient solutions to certain computational tasks than any corresponding classical algorithm. Here we show that a single qudit is s…
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…
Measuring bipartite quantum correlations of an unknown state
I. A. Silva, D. Girolami, R. Auccaise +6
We report the experimental measurement of bipartite quantum correlations of an unknown two-qubit state. Using a liquid state Nuclear Magnetic Resonance (NMR) setup and employing ge…
