Experimental Investigation of Geometric Quantum Speed Limits in an Open Quantum System
Diego Paiva Pires, Eduardo R. deAzevedo, Diogo O. Soares-Pinto +2
We studied geometric quantum speed limits (QSL) of a qubit subject to decoherence in an ensemble of chloroform molecules in a Nuclear Magnetic Resonance experiment. The QSL is a fu…
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…
Dipolar Filtered magic-sandwich-echoes as a tool for probing molecular motions using time domain NMR
Jefferson G. Filgueiras, Uilson B. da Silva, Giovanni Paro +3
We present a simple H NMR approach for characterizing intermediate to fast regime molecular motions using H time-domain NMR at low magnetic field. The method is based on a…
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…
