Secure Controlled Teleportation
Several protocols for controlled teleportation were suggested by Yang, Chu, and Han [PRA 70, 022329 (2004)]. In these protocols, Alice teleports qubits (in an unknown state) to Bob iff a controller allows it. We view this problem in the perspective of secure multi-party quantum computation. We show that the suggested entanglement-efficient protocols for m-qubit controlled teleportation are open...
متن کاملOptimal Teleportation Based on Bell Measurement
We study optimal teleportation based on the Bell measurements. An explicit expression for the quantum channel associated with the optimal teleportation with an arbitrary mixed state resource is presented. The optimal transmission fidelity of the corresponding quantum channel is calculated and shown to be related to the fully entangled fraction of the quantum resource, rather than the singlet fr...
متن کاملEconomical (k, m)-threshold controlled quantum teleportation
We study a (k,m)-threshold controlling scheme for controlled quantum teleportation. A usual polynomial coding over GF(p) with prime p > m − 1 needs to distribute a d-dimensional qudit with d ≥ p to each controller for this purpose. We propose a scheme using m qubits (twodimensional qudits) for the controllers’ portion, following a discussion on the benefit of a quantum control in comparison to ...
متن کاملRealization of Optimal Disentangle- ment by Teleportation via Separable Channel
We discuss here the best disentanglement processes of states of two two–level systems which belong to (i) the universal set, (ii) the set in which the states of one party lie on a single great circle of the Bloch sphere, and (iii) the set in which the states of one party commute with each other, by teleporting the states of one party (on which the disentangling machine is acting) through three ...
متن کاملOptimal teleportation with a mixed state of two qubits.
We consider a single copy of a mixed state of two qubits and derive the optimal trace-preserving local operations assisted by classical communication such as to maximize the fidelity of teleportation that can be achieved with this state. These optimal local operations turn out to be implementable by one-way communication and always yield a teleportation fidelity larger than 2/3 if the original ...
