Quantum coherence and the principle of microscopic reversibility
K. Khan, W. F. Magalhaes, Jailson S. Araujo +2
The principle of microscopic reversibility is a fundamental element in the formulation of fluctuation relations and the Onsager reciprocal relations. As such, a clear description o…
Experimental demonstration of phase estimation advantage in presence of depolarizing noise by using coherent measurements
R. S. Piera, S. P. Walborn, G. H. Aguilar
We report an experimental investigation of the role of measurement in quantum metrology when the states of the probes are mixed. In particular, we investigated optimized local meas…
Interferometric sensing of the tilt angle of a Gaussian beam
S. P. Walborn, G. H. Aguilar, P. L. Saldanha +2
We investigate interferometric techniques to estimate the deflection angle of an optical beam and compare them to the direct detection of the beam deflection. We show that quantum…
Robust interferometric sensing using two-photon interference
G. H. Aguilar, R. S. Piera, P. L. Saldanha +2
Precise measurement of the angular deviation of an object is a common task in science and technology. Many methods use light for this purpose. Some of these exploit interference ef…
Detection of quantum non-Markovianity close to the Born-Markov approximation
Thais de Lima Silva, Stephen P. Walborn, Marcelo F. Santos +2
We calculate in an exact way the conditional past-future correlation for the decay dynamics of a two-level system in a bosonic bath. Different measurement processes are considered.…
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…
