Robust dynamical decoupling
Alexandre M. Souza, Gonzalo A. Álvarez, Dieter Suter
Quantum computers, which process information encoded in quantum mechanical systems, hold the potential to solve some of the hardest computational problems. A substantial obstacle f…
Effects of time reversal symmetry in dynamical decoupling
Alexandre M. Souza, Gonzalo A. Álvarez, Dieter Suter
Dynamical decoupling (DD) is a technique for preserving the coherence of quantum mechanical states in the presence of a noisy environment. It uses sequences of inversion pulses to…
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…
Experimental magic state distillation for fault-tolerant quantum computing
Alexandre M. Souza, Jingfu Zhang, Colm A. Ryan +1
Any physical quantum device for quantum information processing is subject to errors in implementation. In order to be reliable and efficient, quantum computers will need error corr…
