  I propose to replace the dual classical and nonlocal channels used for
teleporting unknown quantum states in the original protocol (OP) [Bennett, C.
H., et al. Phys. Rev. Lett. 70 1895 (1993)] by either (i) one single quantum
channel or (ii) two nonlocal channels in order to turn the OP into an
all-quantum teleportation (AQT) protocol. Ideally, N runs of single channel AQT
can be achieved with a single Einstein-Podolsky-Rosen (EPR) pair, in contrast
with the OP, which consumes N EPR pairs. In the two nonlocal channels proposal,
Alice uses the superdense coding technique to send Bob her result, which makes
AQT more economical than OP.
