Efficient many-party controlled teleportation of multiqubit quantum information via entanglement
We present a way to teleport multiqubit quantum information from a sender to a distant receiver via the control of many agents in a network. We show that the original state of each qubit can be restored by the receiver as long as all the agents collaborate. However, even if one agent does not cooperate, the receiver cannot fully recover the original state of each qubit. The method operates esse...
متن کاملQuantum teleportation.
For continuous variable systems, some protocols for entanglement swapping, establishing entanglement between distant stations through teleportation, testing the efficiency of teleportation with the aid of a third party, and combining teleportation with cloning have been proposed. But no protocol for the explicit teleportation of an entangled continuous variable state exists in the literature, a...
متن کاملQuantum Teleportation
Teleportation the transmission and reconstruction of objects over arbitrary distances is a spectacular process, which actually has been invented by science fiction authors some decades ago. Unbelievable as it seems in 1993 a theoretical scheme has been found by Charles Bennett et al. that predicts the existence of teleportation in reality at least for quantum systems. This scheme exploits some ...
متن کاملQuantum Teleportation
Given a single copy of an unknown quantum state, it is impossible in principle to identify it. The mostly inaccessible information carried by the state is termed quantum information. In contrast to classical information, it cannot be copied or cloned. This concept provides a theoretical underpinning for all aspects of quantum communication and quantum computation. Here we use it to consider qua...
متن کاملMultiqubit Spectroscopy of Gaussian Quantum Noise
We introduce multi-pulse quantum noise spectroscopy protocols for spectral estimation of the noise affecting multiple qubits coupled to Gaussian dephasing environments including both classical and quantum sources. Our protocols are capable of reconstructing all the noise autoand cross-correlation spectra entering the multiqubit dynamics. We argue that this capability is crucial not only for met...
