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 experimentally for all measurement strengths and all post-selected states. This procedure allows us to discuss the physics of modular and weak values in interferometric experiments involving a qubit meter. We determine both the modulus and the argument of the modular value for any measurement strength in a single step, by…

Geometric description of modular and weak values in discrete quantum systems using the Majorana representation
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 symmetric states of N-1
Direct Measurement of a Nonlocal Entangled Quantum State.
TLDR
Here, for the first time, a method is proposed to directly measure a nonlocal wave function of a bipartite system, using modular values, and is experimentally implemented for a photon pair in a hyperentangled state.
Various pointer states approaches to polar modular values
We theoretically analyze the polar decomposition for quantum modular values under various pointer states approaches. We consider both the finite-dimensional discrete pointer state and continuous
Overcoming experimental limitations in a nonlinear two-qubit gate through postselection
TLDR
A modular-value two-qubit gate is introduced and its advantages in experimentally limited situations are explored, including the connection to a postselected cross-phase modulation scenario when a undesired absorption is present.
Delayed choice of paths in the quantum paradox of separating different properties of a photon
The so-called quantum Cheshire Cat is a scenario where a photon, identified with a cat, and a component of its polarization, identified with the grin of that cat, are separated. We observe that the
Can two quantum Cheshire cats exchange grins?
A common-sense perception of a physical system is that it is inseparable from its physical properties. The notion of Quantum Cheshire Cat challenges this, as far as quantum systems are concerned. It
Operational formulation of weak values without probe systems
Weak values are the fundamental values for observables in a pre- and post-selected system. Weak values are typically measured by weak measurement, in which weak values appear in the change of not the
A framework for measuring weak values without weak interactions and its diagrammatic representation
Weak values are typically obtained experimentally by performing weak measurements, which involve weak interactions between the measured system and a probe. However, the determination of weak values
A note concerning the modular valued von Neumann interaction operator
The modular valued operator $${\hat{V}}_m $$V^m of the von Neumann interaction operator for a projector is defined. The properties of $${\hat{V}}_m $$V^m are discussed and contrasted with those of
Linear and nonlinear optical effects in biophotonic structures using classical and nonclassical light
TLDR
The optical study of different biophotonic geometries and biological structures using classical light in linear and nonlinear regime is reviewed, especially highlighting the link between these morphologies and modern biomedical research.

In this paper we present the two-state vector formalism of quantum mechanics. It is a time-symmetrized approach to standard quantum theory particularly helpful for the analysis of experiments
