Some Open Problems in Quantum Information Theory
Mary Beth Ruskai
Some open questions in quantum information theory (QIT) are described. Most of them were presented in Banff during the BIRS workshop on Operator Structures in QIT 11-16 February 20…

Connecting N-representability to Weyl's problem: The one particle density matrix for N = 3 and R = 6
Mary Beth Ruskai
An analytic proof is given of the necessity of the Borland-Dennis conditions for 3-representability of a one particle density matrix with rank 6. This may shed some light on Klyach…

Energy Density-Flux Correlations in an Unusual Quantum State and in the Vacuum
L. H. Ford, Thomas A. Roman
In this paper we consider the question of the degree to which negative and positive energy are intertwined. We examine in more detail a previously studied quantum state of the mass…
