Nuclear Spin 3=2 Electric Quadrupole Relaxation as a Quantum Computation
A. M. Souza, A. Gavini-Viana, I. S. Oliveira +5
In this work we applied a quantum circuit treatment to describe the nuclear spin relax- ation. From the Redfield theory, we were able to describe the quadrupolar relaxation as a co…
A scattering quantum circuit for measuring Bell's time inequality: a nuclear magnetic resonance demonstration using maximally mixed states
A M Souza, I S Oliveira, R S Sarthour
In 1985, Leggett and Garg (1985 Phys. Rev. Lett. 54 857) proposed a Bell-like inequality to test (in)compatibility between two fundamental concepts of quantum mechanics. The first…
Environment-induced sudden transition in quantum discord dynamics
R. Auccaise, L. C. Celeri, D. O. Soares-Pinto +7
Non-classical correlations play a crucial role in the development of quantum information science. The recent discovery that non-classical correlations can be present even in separa…
Writing electronic ferromagnetic states in a high-temperature paramagnetic nuclear spin system
D. O. Soares-Pinto, J. Teles, A. M. Souza +5
In this paper we use the Nuclear Magnetic Resonance (NMR) to write eletronic states of a ferromagnetic system into a high-temperature paramagnetic nuclear spins. Through the contro…
Experimentally Witnessing the Quantumness of Correlations
R. Auccaise, J. Maziero, L. C. Celeri +6
The quantification of quantum correlations (other than entanglement) usually entails laboured numerical optimization procedures also demanding quantum state tomographic methods. Th…
