Improving the convergence of an iterative algorithm for solving arbitrary linear equation systems using classical or quantum binary optimization
Erick R. Castro, Eldues O. Martins, Roberto S. Sarthour +2
Recent advancements in quantum computing and quantum-inspired algorithms have sparked renewed interest in binary optimization. These hardware and software innovations promise to re…
Intrinsic bounds of a two-qudit random evolution
A. Z. Khoury, A. M. Souza, L. E. Oxman +3
We investigate entangled qudits evolving under random, local operations and demonstrate that this evolution is constrained by intrinsic bounds, showing robust features of t…
Experimental demonstration of information to energy conversion in a quantum system at the Landauer Limit
John P. P. Silva, Roberto S. Sarthour, Alexandre M. Souza +5
Landauer's principle sets fundamental thermodynamical constraints for classical and quantum information processing, thus affecting not only various branches of physics, but also of…
Spin squeezing in an ensemble of quadrupolar nuclei NMR system
R. Auccaise, A. G. Araujo-Ferreira, R. S. Sarthour +3
We have characterized spin-squeezed states produced at a temperature of on a Nuclear Magnetic Resonance (NMR) quadrupolar system. The implementation is carrie…
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…
Classical bifurcation in a quadrupolar NMR system
A. G. Araujo-Ferreira, R. Auccaise, R. S. Sarthour +3
The Josephson Junction model is applied to the experimental implementation of classical bifurcation in a quadrupolar Nuclear Magnetic Resonance system. There are two regimes, one l…
