Boosting State Discrimination in Quantum Brownian Motion Channel via Memory-Induced Coherence Preservation
João C. P. Porto, Pedro R. Dieguez, Carlos H. S. Vieira +3
Preserving quantum resources in dissipative environments is a fundamental challenge in quantum information processing. While environmental interactions usually degrade quantum reso…
Towards gravimetry enhancement with squeezed states
Oziel R. de Araujo, Lucas S. Marinho, Jonas F. G. Santos +1
We investigate the sensitivity of gravitational acceleration estimation using squeezed probe states in a quantum metrology framework. In particular, we analyze how the squeezing ph…
Weak-to-Strong Measurement Transition with Thermal Instabilities: From Anomalous Amplification to Metrological Sensitivity
Marcos V. S. Lima, Carlos H. S. Vieira, Irismar G. da Paz +2
Quantum measurement is physically realized through a finite dynamical interaction between a system and a measuring apparatus, giving rise to a continuous transition from weak to st…
Multiparameter estimation with position-momentum correlated Gaussian probes
João C. P. Porto, Carlos H. S. Vieira, Pedro R. Dieguez +2
Gaussian quantum probes have been widely used in quantum metrology and thermometry, where the goal is to estimate the temperature of an environment with which the probe interacts.…
Temperature and non-Markovian parameter estimation in quantum Brownian motion
João C. P. Porto, Carlos H. S. Vieira, Irismar G. da Paz +2
We investigate a quantum metrological protocol operating in a non-Markovian environment by employing the quantum Brownian motion (QBM) model, in which the system is linearly couple…
Matter-Wave Squeezing from Gouy Phase: Toward a New Tool for Quantum Technology
Thiago M. S. Oliveira, Lucas S. Marinho, F. C. V. de Brito +2
We investigate the Gouy phase emerging from the time evolution of confined matter waves in a harmonic potential. Specifically, we analyze the quantum dynamics of a Gaussian wavepac…
