Absorption-based qubit estimation in discrete-time quantum walks
Edgard P. M. Amorim, Lorena R. Cerutti, O. P. de Sá Neto +1
We investigate state estimation in discrete-time quantum walks with a single absorbing boundary. Using a spectral approach, we obtain closed expressions for the escape probability…

Collective Dissipation and Parameter Sensitivity in Trapped Ions Coupled to a Common Thermal Reservoir
C. F. P. Avalos, G. A. Prataviera, M. C. de Oliveira
We investigate the dynamics of two trapped ions interacting with a common thermal reservoir, focusing on how cross-correlated dissipation influences heating, steady-state behavior,…
