Abstract

The amount of entanglement necessary to teleport quantum states drawn from general ensemble \p_i,ρ_i\ is derived. The case of perfect transmission of individual states and that of asymptotically faithful transmission are discussed. Using the latter result, we also derive the optimum compression rate when the ensemble is compressed into qubits and bits.
