Query: Allowed and Forbidden Bipartite Correlations from Thermal States   The strong connection between correlations and quantum thermodynamics raises
a natural question about the preparation of correlated quantum states from two
copies of a thermal qubit. In this work we study the specific forms of allowed
and forbidden bipartite correlations. As a consequence, we extend the result to
Separable (SEP) but not Absolutely Separable (AbSEP) class of product states.
Preparation of a general form of entanglement from arbitrary thermal qubits is
studied and as an application we propose a strategy to establish sustained
entanglement between two distant parties. The threshold temperature to produce
entanglement from two copies of a thermal qubit has also been discussed from
the resource theoretic perspective, which ensures that the bound on the
temperature can be superseded with the help of a resource state. A dimension
dependent upper-bound on the temperature is derived, below which two copies of
any d-dimensional thermal state can be entangled in 2xd dimension.
