Quantum foundations are still unsettled, with mixed effects on science and society. By now it
should be possible to obtain consensus on at least one issue: Are the fundamental …

Entanglement is nowadays considered as a key quantity for the understanding of
correlations, transport properties and phase transitions in composite quantum systems, and …

A single quantum particle can be described by a wavefunction that spreads over arbitrarily
large distances; however, it is never detected in two (or more) places. This strange …

Quantum superposition is the quantum-mechanical property of a particle whereby it inhabits
several of its possible quantum states simultaneously. Ideally, this permissible coexistence …

Flavor oscillations in elementary particle physics are related to multimode entanglement of
single-particle states. We show that mode entanglement can be expressed in terms of flavor …

In molecular double-slit experiments, the interference between emitted core electrons of
diatomic molecules gives rise to oscillations in the observed electron intensity. Here, we …

In the Aharonov-Bohm (AB) effect, a superposed charge acquires a detectable phase by
enclosing an infinite solenoid, in a region where the solenoid's electric and magnetic fields …

A novel prediction is derived by the Two-State-Vector-Formalism (TSVF) for a particle
superposed over three boxes. Under appropriate pre-and post-selections, and with …

In the physics of flavor mixing, the flavor states are given by superpositions of mass
eigenstates. By using the occupation number to define a multiqubit space, the flavor states …

We discuss the interferometric scheme put forward by Tan, Walls, and Collett (TWC) that
claims to reveal Bell non-classicality of a single photon. We show that the violation of local …
