Operator noncommutation, a hallmark of quantum theory, limits measurement precision,
according to uncertainty principles. Wielded correctly, though, noncommutation can boost …

The brain is composed of electrically excitable neuronal networks regulated by the activity of
voltage-gated ion channels. Further portraying the molecular composition of the brain …

This review, of the understanding of quantum mechanics, is broad in scope, and aims to
reflect enough of the literature to be representative of the current state of the subject. To …

Weak values have been shown to be helpful especially when considering them as the
outcomes of weak measurements. In this paper we show that, in principle, the real and …

Entanglement measures quantify the amount of quantum entanglement that is contained in
quantum states. Typically, different entanglement measures do not have to be partially …

Sequential weak measurements of non-commuting observables are not only fundamentally
interesting in terms of quantum measurement but also show potential in various …

The biological order provided by α-helical secondary protein structures is an important
resource exploitable by living organisms for increasing the efficiency of energy transport. In …

We investigate four key issues with using a nonzero weak value of the spatial projection
operator to infer the past path of an individual quantum particle. First, we note that weak …

The two-state-vector formalism and the entangled histories formalism are attempts to better
understand quantum correlations in time. Both formalisms share some similarities, but they …

In this somewhat pedagogical paper we revisit complementarity relations in bipartite
quantum systems. Focusing on continuous-variable systems, we examine the influential …
