| contents | We propose a teleportation protocol that enables perfect transmission of a qubit using a partially entangled two-qutrit quantum channel. Within our scheme, we analyze the relationship among the three key ingredients of teleportation: (i) the quantum channel, (ii) the sender's (Alice's) measurement operations, and (iii) the classical information transmitted to the receiver (Bob). Compared to Gour's protocol \cite{PRA2004}, our scheme requires less entanglement of Alice's measurement and fewer classical bits sent to Bob.Our results also show a trade-off between these two resources and derive a lower bound for their sum, quantifying their interplay in the teleportation process. |
