Temperature-independent teleportation of qubits in Davies environments
Dawid Kłoda, Jerzy Dajka · Quantum Information Processing · 2014
A quantum channel teleporting qubits from Alice to Bob is considered in which the bipartite resource state shared by Alice and Bob is affected by bilocal thermal noise treated in rigorous Davis approximation. Specific conditions are identified where the fidelity of the teleportation channel can be either independent of temperature or even enhanced by the temperature of the environment.
