Experimental Demonstration of Secure Communication based on Quantum Illumination

Zheshen Zhang, Maria Tengner, Tian Zhong +2 more

Abstract: We report the first experimental demonstration of an entanglement-based secure communication protocol that is resilient to entanglement-breaking loss and noise on the communication channel. Passive eavesdropping immunity is demonstrated in bit-error rate measurements and Alice’s information advantage over Eve is estimated. Entanglement is a key ingredient to many quantum information applications, but quantum decoherence arising from loss and noise easily destroys entanglement. Quantum illumination (QI) [1]–[3] is a novel concept of utilizing entanglement in an entanglement-breaking lossy and noisy environment to achieve a substantial performance benefit. First proposed for enhancing the signalto-noise ratio for detecting a weakly-reflecting target in the presence of strong background noise [1], quantum illumination was later shown, theoretically, to enable high data-rate classical communication that is immune to passive eavesdropping [3]. In this work we report the first experimental demonstration of the QI communication protocol [4], showing a strong performance benefit of using bosonic entanglement over an entanglement-breaking channel and QI’s passive-eavesdropping immunity. Quantum illumination achieves a substantial benefit from its initial entanglement, despite the roundtrip lossy, noisy propagation channel’s having left the retained and returned lightAbstract: We report the first experimental demonstration of an entanglement-based secure communication protocol that is resilient to entanglement-breaking loss and noise on the communication channel.

High fidelity quantum blind dual-signature protocols

Minghui Zhang, Jiahui Xie

This work proposes two kinds of fault tolerant quantum blind dual-signature (QBDS) protocols with photon quartets, which are robust against the collective-dephasing noise and collective-rotation noise, respectively. In the protocols, the initial information needs to be signed by the message owner in addition to the signer, which will be well suitable for application in some E-payment and E-government systems that require the message owner to provide authentication information. Both QBDS protocols are constructed with logical qubits which are immune to the collective noise, thereby the protocols can provide higher communication fidelity with respect to the existing quantum signature protocols. Furthermore, the protocols had been proved to be secure against some individual eavesdropping attacks. Meanwhile, the protocols satisfy the characteristics of quantum blind signature (QBS) protocols such as unforgeability, undeniability and blindness.This work proposes two kinds of fault tolerant quantum blind dual-signature (QBDS) protocols with photon quartets, which are robust against the collective-dephasing noise and collective-rotation noise, respectively.
