Thermodynamical aspects of optically pumped dense atomic medium
A. F. Sousa, C. H. S. Vieira, H. M. Florez
Optically Pumped Magnetometers use light to drive an atomic vapor into a Non-Equilibrium Steady State for sensing. This kind of state is achieved when spin-exchange collisions, tog…
Probing parameters estimation with Gaussian non-commutative measurements
Alice P. G. Hall, Carlos H. S. Vieira, Jonas F. G. Santos
Gaussian quantum states and channels are pivotal across many branches of quantum science and their applications, including the processing and storage of quantum information, the in…
Improving parameters estimation in Gaussian channels using quantum coherence
Jonas F. G. Santos, Carlos H. S. Vieira, Wilder R. Cardoso
Gaussian quantum channels are relevant operations in continuous variable systems. In general, given an arbitrary state, the action on it is well-known provided that the quantum cha…
Two-stroke thermal machine using spin squeezing operation
Carlos H. S. Vieira, Jonas F. G. Santos
Quantum thermal machines are powerful platforms for investigating how quantum effects impact the energy flow between different systems. Here, we investigate a two-stroke cycle in w…
