Leggett and Garg formulated macrorealist models encoding our intuition on classical
systems, ie, physical quantities have a definite value that can be measured with minimal …

We theoretically formulate and experimentally demonstrate a secure scheme for semi-
device-independent quantum random number generation by utilizing Leggett-Garg …

Nuclear magnetic resonance is arguably both the best available quantum technology for
implementing simple quantum computing experiments and the worst technology for building …

Leggett-Garg's inequalities predict sharp bounds for some classical correlation functions that
address the quantum or classical nature of real-time evolutions. We experimentally observe …

Macroscopic realism (MR) is the notion that a time-evolving system possesses definite
properties, irrespective of past or future measurements. Quantum-mechanical theories can …

Macrorealism (MR) is the worldview that certain quantities may take definite values at all
times irrespective of past or future measurements and may be experimentally falsified via the …

Macroscopic realism (MR) is the view that a system may possess definite properties at any
time independent of past or future measurements and may be tested experimentally using …

We consider two different types of conditions which were proposed to test macrorealism in
the context of a system described by a single dichotomic variable Q. This is the view that a …

We investigate the relation between a refined version of Leggett and Garg conditions for
macrorealism, namely, the no-signaling-in-time (NSIT) conditions, and the quantum …

Leggett-Garg (LG) tests for macrorealism were originally designed to explore quantum
coherence on the macroscopic scale. Interference experiments and systems modeled by …
