Deterministic quantum communication in presence of controlled noise: An experimantal test

Abstract

An individual incoherent eavesdropping on a two-way quantum protocol for deterministic communication without entanglement is stimulated. The results show that the protocol remains secure regardless of the noise caused by the eavesdropper.

Experimental Test of Two-Way Quantum Key Distribution in the Presence of Controlled Noise

Alessandro Ceré, Marco Lucamarini, Giovanni Di Giuseppe +1 more

We describe the experimental test of a quantum key distribution performed with a two-way protocol without using entanglement. An individual incoherent eavesdropping is simulated and induces a variable amount of noise on the communication channel. This allows a direct verification of the agreement between theory and practice.

Secure Deterministic Communication without Entanglement

Marco Lucamarini, Stefano Mancini

We propose a protocol for deterministic communication that does not make use of entanglement. It exploits nonorthogonal states in a two-way quantum channel to attain unconditional security and high efficiency of the transmission. We explicitly show the scheme is secure against a class of individual attacks regardless of the noise on the channel. Its experimental realization is feasible with current technology.

Individual incoherent eavesdropping on a two-way quantum communication protocol

Giovanni Di Giuseppe, Marco Lucamarini, Alessandro Ceré +1 more

One-way quantum channels play a fundamental role in the security of the communication between two distant parties, in particular within the frame of "quantum key distribution". Nevertheless quite recently it has been introduced the possibility of using two-way quantum channels for the same purpose. Although the first attempts in this direction did not feature any particular advantage with respect to the one-way counterpart some recent results obtained by our group suggest that this new class of protocols provides higher thresholds of security.

Deterministic secure quantum communication with and without entanglement

Tarek A. Elsayed

Abstract We present a protocol for sending a message over a quantum channel with different layers of security that will prevent an eavesdropper from deciphering the message without being detected. The protocol has two versions where the bits are encoded in either pairs of entangled photons or separate photons. Unlike many other protocols, it requires a one-way, rather than a two-way, quantum channel and does not require a quantum memor. A quantum key is used to encrypt the message and both the key and the message are sent over the quantum channle with the same quantum encoding technique. The key is sent only if no eavesdropper is detected.

Two-way Secure Communication Using Quantum Illumination

Maria Tengner, Tian Zhong, Franco N. C. Wong +1 more

A two-way entanglement-based communication protocol resilient to high loss and noise is implemented. Even though the entanglement is lost during transmission, efficient communication that is secure against passive eavesdropping is possible.

Eavesdropping on the LM05 secure communication protocol

W oacute jcik Antoni, Hausmann Krystian

Security of the two-way quantum communication protocol proposed by Lucamarini and Mancini (Phys. Rev. Lett. 94 (2005) 140501) can be impaired in the case of considerable quantum channel noise. We present scheme which considers the opportunity of eavesdropping due to a separation of two procedures, namely, the verification procedure and the communication procedure.
