Accelerating Fourier--Motzkin elimination: redundancy removal and the choice of variable elimination order
Shashaank Khanna
Fourier-Motzkin elimination computes an inequality description of the projection of a polyhedron onto a subset of its coordinates by eliminating one variable at a time. It is used…

Spurious quantum correlations
Shashaank Khanna, Matthew F. Pusey, Roger Colbeck
In his seminal paper, Bell [Physics Physique Fizika 1, 195 (1964)] considers the correlations that result from space-like separated measurements on a pair of entangled particles. H…

Closing the problem of which causal structures of up to six total nodes have a classical-quantum gap
Shashaank Khanna, Matthew Pusey, Roger Colbeck
The discovery of Bell that there exist quantum correlations that cannot be reproduced classically is one of the most important in the foundations of quantum mechanics, as well as h…
