Dynamical discontinuities in repeated weak measurements revealed by complex weak values
Lorena Ballesteros Ferraz
This work demonstrates that repeated weak measurements together with post-selection can produce sharp dynamical discontinuities in meter observables, even in minimal quantum system…

Temperature-induced measurement sensitivity enhancement via imaginary weak values
Lorena Ballesteros Ferraz, Alexandre Matzkin, Alok Kumar Pan
We investigate the potential of weak measurement and post-selection to enhance measurement sensitivity when the initial probe state is mixed. In our framework, the mixedness of the…

Weak continuous measurements require more work than strong ones
Lorena Ballesteros Ferraz, Cyril Elouard
Understanding the energy cost of quantum measurement process and its connection to the measurement performance faces the challenge of modeling the objectification process. The latt…
