Spooky Action at a Distance
Published 25 May 2020 in quant-ph | (2005.11870v1)
Abstract: This article studies quantum mechanical entanglement. We begin by illustrating why entanglement implies action at a distance. We then introduce a simple criterion for determining when a pure quantum state is entangled. Finally, we present a measure for the amount of entanglement for a pure state.
