Strengthening weak-value amplification with recycled photons
We consider the use of cyclic weak measurements to improve the sensitivity of weak-value amplification precision measurement schemes. …

Weak values are universal in von Neumann measurements
We refute the widely held belief that the quantum weak value necessarily pertains to weak measurements. To accomplish this, we use the …

Contextual-value approach to the generalized measurement of observables
We present a detailed motivation for and definition of the contextual values of an observable, which were introduced by Dressel et al. …

Measuring which-path information with coupled electronic Mach-Zehnder interferometers
We theoretically investigate a generalized “which-path” measurement on an electronic Mach-Zehnder Interferometer (MZI) implemented via …

Significance of the imaginary part of the weak value
Unlike the real part of the generalized weak value of an observable, which can in a restricted sense be operationally interpreted as an …

Sufficient conditions for uniqueness of the weak value
We review and clarify the sufficient conditions for uniquely defining the generalized weak value as the weak limit of a conditioned …

Experimental violation of two-party Leggett-Garg inequalities with semiweak measurements
We generalize the derivation of Leggett-Garg inequalities to systematically treat a larger class of experimental situations by allowing …

Contextual values of observables in quantum measurements
We introduce contextual values as a generalization of the eigenvalues of an observable that takes into account both the system …
