“…In the counterfactual context, the adversary (Eve) is accessible only to the quantum channel between the two end parties. Since only the H photon component, which carries no information, passes through the quantum channel in the H-CQZ gate, no information is available to Eve from the quantum channel [ 36 ]. Therefore, Eve cannot apply conventional attack strategies to get the quantum and classical side information.…”

“…In our proposed protocol, the anonymous entanglement between the sender and receiver mainly relies on the counterfactual GHZ state distribution. Under the noisy quantum framework, the GHZ state shared among the participants is encompassed within the noise operator described by

“…The main difference between the conventional GHZ-based AQT and our proposed protocol is the distribution of the GHZ state. Since counterfactual communication is robust against dephasing noise [ 36 ], it allows a GHZ state distribution employing this property to remain unaffected by it as well. The fidelity of these protocols is plotted as a function of noise for

and

participants in Figure 5 .…”

Hiding the identity of involved participants in the network, known as anonymity, is a crucial issue in some cryptographic applications such as electronic voting systems, auctions, digital signatures, and Byzantine agreements. This paper proposes a new anonymous quantum teleportation protocol based on counterfactual communication where no information-carrying particles pass through the channel. It is achieved by the distribution of a counterfactual entanglement among the participants in the network followed by the establishment of an anonymous entanglement between the sender and the receiver. Afterwards, the sender can anonymously teleport a quantum state to the receiver by utilizing the anonymous entanglement. However, the practicality of the anonymous quantum network mainly calls for two performance measures—robustness against adversarial attacks and noisy environments. Motivated by these demands, firstly, we prove the security of our proposed protocol and show that it achieves both the sender and receiver’s anonymity in the presence of active adversaries and untrusted parties. Along with anonymity, we also ensure the correctness of the protocol and the privacy of the teleported qubit. Finally, we analyze the robustness of our proposed protocol under the presence of channel noise and compare its fidelity with those of the conventional protocols. The main advantage of our proposed protocol is that it can provide useful anonymous quantum resources for teleportation under noisy environment with a higher security compared to previous protocols.

“…Counterfactual quantum key distribution has unique counterfactual quantum effects, based on the principle of nointeraction measurement (IFM), which can be seen as communicating parties in a real environment without transmitting particles carrying any secret information, contrary to the actual situation. Counterfactual quantum key distribution, as a research with real experimental equipment at the current stage, is receiving great attention from research scholars, applying counterfactual quantum key distribution in other directions, such as quantum privacy queries [1], quantum identity authentication [2], and quantum teleportation [3].…”

To save quantum resources and improve efficiency, this article proposes an efficient counterfactual quantum privacy query protocol. Counterfactual quantum privacy query refers to the identification of secure detection and key screening based on the detector's response results without the actual transmission of quantum information between user Bob and database Alice. Alice completes key transmission through a counterfactual device, while Bob measures the photon's polarization with a probability of 1/2 to obtain the encoded classical information, followed by traditional post-processing and privacy query operations. Additionally, to withstand the noise impact during the communication process, a modified counterfactual QKD protocol proposed by Rao (2021) is utilized, where communication parties randomly select a quantum bit flip with a specified probability \textit{f}, and then complete the quantum privacy query.
