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…
Effects of clays on spin-spin relaxation: a route for non-invasive total clay content quantification
Jefferson G. Filgueiras, Matheus S. J. de Miranda, Carla S. Semiramis +1
Clay minerals are important components of sandstone rocks, due to their significant role in petrophysical properties like porosity and permeability. These minerals have a particula…
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…
Continuous variables quantum computation over the vibrational modes of a single trapped ion
Luis Ortiz-Gutiérrez, Bruna Gabrielly, Luis F. Muñoz +3
We consider the quantum processor based on a chain of trapped ions to propose an architecture wherein the motional degrees of freedom of trapped ions (position and momentum) could…
Construction of Arbitrary Robust One-Qubit Operations Using Planar Geometry
Tsubasa Ichikawa, Jefferson G. Filgueiras, Masamitsu Bando +3
We show how to construct an arbitrary robust one-qubit unitary operation with a control Hamiltonian of , where is a Pauli matrix and is piec…
Using the Quantum Zeno Effect for Suppression of Decoherence
Yasushi Kondo, Yuichiro Matsuzaki, Kei Matsushima +1
Projective measurements are an essential element of quantum mechanics. In most cases, they cause an irreversible change of the quantum system on which they act. However, measuremen…
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…
