• Abstract: We explicitly show that the quantum teleportation protocol can be employed to completely reconstruct arbitrary two- and three-qubit density matrices. We also extend the present analysis to n-qubit density matrices. The only quantum resources needed to implement the teleportation-based quantum state tomography protocol are the ability to make Bell measurements and the ability to prepare a few different single qubit states to be teleported from Alice to Bob.

  Quantum teleportation has proven to be fundamental for many quantum information and communication processes. For linear-optical systems, the efficiency of teleportation is directly linked to the success probability of the involved Bell-state measurement. Here, we demonstrate quantum teleportation surpassing this limit.

  We propose a new concept, oblivious computation quantum computation, where secrecy of the input qubits and the program to identify the quantum gates are required. Exploiting quantum teleportation, we propose a two-server protocol for this task. Also, we discuss delegated multiparty quantum computation, in which, several users ask multiparty quantum computation to server(s) only using classical communications.

• Quantum Teleportation with One Classical Bit [0.0]
  Quantum teleportation allows one to transmit an arbitrary qubit from point A to point B using a pair of entangled qubits and classical bits of information. The conventional protocol for teleportation uses two bits of classical information and assumes that the sender has access to only one copy of the arbitrary qubit to the sent. We propose a modified quantum teleportation protocol that allows Alice to reset the state of the entangled pair to its initial state using only local operations.

• Perfect teleportation with a partially entangled quantum channel [4.9395337334694105]
  Quantum teleportation provides a way to transfer unknown quantum states from one system to another via an entangled state as a quantum channel without physical transmission of the object itself. The entangled channel, measurement performed by the sender (Alice), and classical information sent to the receiver (Bob) are three key ingredients in the procedure, which need to cooperate with each other. We propose a scheme for perfect teleportation of a qubit through a high-dimensional quantum channel in a pure state with two equal largest Schmidt coefficients.
