Deterministic Microwave-Optical Transduction Based on Quantum Teleportation

All-optical quantum teleportation.

We propose an all-optical continuous-variable quantum teleportation scheme based on optical parametric amplifiers.

Quantum Multi-Signature Protocol Based on Teleportation

In this paper, a protocol which can be used in multi-user quantum signature is proposed. The scheme of signature and verification is based on the correlation of Greenberger-Horne-Zeilinger (GHZ) states and the controlled quantum teleportation. Different from the digital signatures, which are based on computational complexity, the proposed protocol has perfect security in the noiseless quantum c...

Deterministic teleportation of electrons in a quantum dot nanostructure.

We present a proposal for deterministic quantum teleportation of electrons in a semiconductor nanostructure consisting of a single and a double quantum dot. The central issue addressed in this Letter is how to design and implement the most efficient--in terms of the required number of single and two-qubit operations--deterministic teleportation protocol for this system. Using a group-theoretica...

Deterministic teleportation of a quantum gate between two logical qubits

A quantum computer has the potential to efficiently solve problems that are intractable for classical computers. Constructing a largescale quantum processor, however, is challenging due to errors and noise inherent in real-world quantum systems. One approach to this challenge is to utilize modularity—a pervasive strategy found throughout nature and engineering— to build complex systems robustly...
