Testing Whether Gravity Acts as a Quantum Entity When Measured

Farhan Hanif, Debarshi Das, Jonathan Halliwell +4

A defining signature of classical systems is "in principle measurability" without disturbance: a feature manifestly violated by quantum systems. We describe a multi-interferometer…

Leggett-Garg violations for continuous variable systems with gaussian states

Clement Mawby, Jonathan Halliwell

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

Leggett-Garg tests for macrorealism in the quantum harmonic oscillator and more general bound systems

Clement Mawby, Jonathan Halliwell

The Leggett-Garg (LG) inequalities were introduced to test for the possible presence of macroscopic quantum coherence. Since such effects may be found in various types of macroscop…

Detecting violations of macrorealism when the original Leggett-Garg inequalities are satisfied

Shayan Majidy, Jonathan J. Halliwell, Raymond Laflamme

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

Conditions for Macrorealism for Systems Described by Many-Valued Variables

J. J. Halliwell, C. Mawby

Macrorealism (MR) is the view that a system evolving in time possesses definite properties independent of past or future measurements and is traditionally tested for systems descri…

Exploration of an augmented set of Leggett-Garg inequalities using a noninvasive continuous-in-time velocity measurement

Shayan-Shawn Majidy, Hemant Katiyar, Galit Anikeeva +2

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 th…
