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 …

Technical advantages for weak-value amplification: when less is more
The technical merits of weak-value-amplification techniques are analyzed. We consider
models of several different types of technical noise in an optical context and show that weak …
