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…
High-fidelity gate operations for quantum computing beyond dephasing time limits
Alexandre M. Souza, Roberto S. Sarthour, Ivan S. Oliveira +1
The implementation of quantum gates with fidelities that exceed the threshold for reliable quantum computing requires robust gates whose performance is not limited by the precision…
Quantum process tomography with informational incomplete data of two -coupled heterogeneous spins relaxation in a time window much greater than
Thiago O. Maciel, Reinaldo O. Vianna, Roberto S. Sarthour +1
We reconstruct the time dependent quantum map corresponding to the relaxation process of a two-spin system in liquid-state NMR at room temperature. By means of quantum tomography t…
