The power of a shared singlet state, compared with a shared reference frame
arXiv:1811.05657 · doi:10.1103/PhysRevA.100.022329
Abstract
We show that a Shared Singlet State (SSS) can supersede a Shared Reference Frame (SRF) in certain quantum communication tasks, i.e. tasks in which two remote players are required to estimate certain parameters of a two particle state sent to them. This shows that task specific value of resources maybe some what different from their common values based on their exchange possibilities.
