Exposure of subtle multipartite quantum nonlocality
M. M. Taddei, T. L. Silva, R. V. Nery +3
The celebrated Einstein-Podolsky-Rosen quantum steering has a complex structure in the multipartite scenario. We show that a naively defined criterion for multipartite steering all…
Error-run-time trade-off in the adiabatic approximation beyond scaling relations
M. R. Passos, M. M. Taddei, R. L. de Matos Filho
The use of the adiabatic approximation in practical applications, as in adiabatic quantum computation, demands an assessment of the errors made in finite-time evolutions. Aiming at…
Distillation of quantum steering
R. V. Nery, M. M. Taddei, P. Sahium +3
We show -- both theoretically and experimentally -- that Einstein-Podolsky-Rosen steering can be distilled. We present a distillation protocol that outputs a perfectly correlated s…
Quantum superpositions of causal orders as an operational resource
Márcio M. Taddei, Ranieri V. Nery, Leandro Aolita
Causal nonseparability refers to processes where events take place in a coherent superposition of different causal orders. These may be the key resource for experimental violations…
