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…

Characterizing entangled state update in different reference frames with weak measurements
Jawad Allam, Alex Matzkin
The evolution of the quantum state of a system upon measurement results in state update. In this work, we investigate the characterization of updated states of multi-partite entang…
