| 摘 要： | This paper proposes a scheme to teleport an arbitrary mixture of diagonal states of multiqutrit via classical correlation and classical communication. To teleport an arbitrary mixture of diagonal states of N qutrits, N classically correlated pairs of two qutrits are used as channel. The sender （Alice） makes Fourier transform and conditional gate （i.e., XOR（3） gate） on her qutrits and does measurement in appropriate computation bases. Then she sends N ctrits to the receiver （Bob）. Based on the received information, Bob performs the corresponding unitary transformation on his qutrits and obtains the teleported state. Teleportation of an arbitrary mixture of diagonal states of multiqudit is also discussed.

| Abstract: | This paper proposes a scheme to teleport an arbitrary mixture of
diagonal states of multiqutrit via classical correlation and
classical communication. To teleport an arbitrary mixture of
diagonal states of N qutrits, N classically correlated pairs of
two qutrits are used as channel. The sender (Alice) makes Fourier
transform and conditional gate (i.e., XOR^{(3)} gate) on her
qutrits and does measurement in appropriate computation bases. Then
she sends N ctrits to the receiver (Bob). Based on the received
information, Bob performs the corresponding unitary transformation
on his qutrits and obtains the teleported state. Teleportation of an
arbitrary mixture of diagonal states of multiqudit is also
discussed. |
