Nonselective generalized measurements as a resource for quantum thermal machines in a double quantum dot
Bruno Carvalho, Jonas F. G. Santos, Moises Rojas
We investigated quantum thermal machines powered by sequential nonselective generalized measurements, taking a double quantum dot with coherent interdot tunneling as a working subs…
Anomaly to Resource: The Mpemba Effect in Quantum Thermometry
Pritam Chattopadhyay, Jonas F. G. Santos, Avijit Misra
Quantum thermometry provides a key capability for nanoscale devices and quantum technologies, but most existing strategies rely on probes initialized near equilibrium. This equilib…
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…
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…
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…
The role of position momentum correlations in coherence freezing and purity behavior
Pedro P. da Silva, Carlos H. S. Vieira, Jonas F. G. Santos +3
We explore the effects of Markovian bath coupling and initial position-momentum correlations on the coherence and purity of Gaussian quantum states. Our analysis focuses on the rol…
