On the relevance of weak measurements in dissipative quantum systems
Lorena Ballesteros Ferraz, John Martin, Yves Caudano
We investigate the impact of dissipation on weak measurements. While weak measurements have been successful in signal amplification, dissipation can compromise their usefulness. Mo…
Revisiting weak values through non-normality
Lorena Ballesteros Ferraz, Riccardo Muolo, Yves Caudano +1
Quantum measurement is one of the most fascinating and discussed phenomena in quantum physics, due to the impact on the system of the measurement action and the resulting interpret…
Geometrical interpretation of the argument of weak values of general observables in N-level quantum systems
Lorena Ballesteros Ferraz, Dominique L. Lambert, Yves Caudano
Observations in quantum weak measurements are determined by complex numbers called weak values. We present a geometrical interpretation of the argument of weak values of general He…
Geometric description of modular and weak values in discrete quantum systems using the Majorana representation
Mirko Cormann, Yves Caudano
We express modular and weak values of observables of three- and higher-level quantum systems in their polar form. The Majorana representation of N-level systems in terms of symmetr…
Interferences in quantum eraser reveal geometric phases in modular and weak values
Mirko Cormann, Mathilde Remy, Branko Kolaric +1
In this letter, we present a new procedure to determine completely the complex modular values of arbitrary observables of pre- and post-selected ensembles, which works experimental…
