Multiparty Controlled CSMA/CD Quantum Communication Scheme
نویسندگان
چکیده
By utilizing the order rearrangement of the single photon sequence and unitary transformations, a multiparty controlled quantum communication scheme for Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is presented. In this scheme, messages can only be recovered by the receivers with the permission of all controllers. It is shown that the security of messages transmission can be ensured and the performance of the proposed scheme enhances significantly since the collision can be avoided.

متن کاملMultiparty controlled quantum secure direct communication using Greenberger–Horne–Zeilinger state
Based on the idea of dense coding of three-photon entangled state and qubit transmission in blocks, we present a multiparty controlled quantum secret direct communication scheme by using Greenberger–Horne–Zeilinger state. In the present scheme, the sender transmits three bits of secret message to the receiver directly and the secret message can only be recovered by the receiver under the permis...

Based on a quantum secure direct communication (QSDC) protocol [Phys. Rev. A69(04)052319], we propose a (n, n)-threshold scheme of multiparty quantum secret sharing of classical messages (QSSCM) using only single photons. We take advantage of this multiparty QSSCM scheme to establish a scheme of multiparty secret sharing of quantum information (SSQI), in which only all quantum information recei...
متن کاملQuantum secure direct communication based on order rearrangement of single photons
Based on the ideal of order rearrangement and block transmission of photons, we present a quantum secure direct communication scheme using single photons. The security of the present scheme is ensured by quantum no-cloning theory and the secret transmitting order of photons. The present scheme is efficient in that all of the polarized photons are used to transmit the sender’s secret message exc...
متن کاملLong-distance measurement-device-independent multiparty quantum communication.
The Greenberger-Horne-Zeilinger (GHZ) entanglement, originally introduced to uncover the extreme violation of local realism against quantum mechanics, is an important resource for multiparty quantum communication tasks. But the low intensity and fragility of the GHZ entanglement source in current conditions have made the practical applications of these multiparty tasks an experimental challenge...
