Colloquium: Understanding quantum weak values: Basics and applications
Since its introduction 25 years ago, the quantum weak value has gradually transitioned from
a theoretical curiosity to a practical laboratory tool. While its utility is apparent in the recent …

Nonperturbative theory of weak pre-and post-selected measurements
This paper starts with a brief review of the topic of strong and weak pre-and post-selected
(PPS) quantum measurements, as well as weak values, and afterwards presents original …

Direct measurement of the quantum wavefunction
The wavefunction is the complex distribution used to completely describe a quantum system,
and is central to quantum theory. But despite its fundamental role, it is typically introduced as …

Measuring small longitudinal phase shifts: weak measurements or standard interferometry?
Recently, weak measurements were used to measure small effects that are transverse to the
propagation direction of a light beam. Here we address the question of whether weak …

Anomalous weak values are proofs of contextuality
MF Pusey - Physical review letters, 2014 - APS
The average result of a weak measurement of some observable A can, under postselection
of the measured quantum system, exceed the largest eigenvalue of A. The nature of weak …

Experimental joint weak measurement on a photon pair as a probe of Hardy's paradox
JS Lundeen, AM Steinberg - Physical review letters, 2009 - APS
It has been proposed that the ability to perform joint weak measurements on postselected
systems would allow us to study quantum paradoxes. These measurements can investigate …

Complex weak values in quantum measurement
R Jozsa - Physical Review A—Atomic, Molecular, and Optical …, 2007 - APS
In the weak value formalism of Aharonov et al., the weak value A w of any observable A is
generally a complex number. We derive a physical interpretation of its value in terms of the …

Direct measurement of the density matrix of a quantum system
One drawback of conventional quantum state tomography is that it does not readily provide
access to single density matrix elements since it requires a global reconstruction. Here, we …
