“…[31,[35][36][37] Recently, studies on the effect of counter-clockwise and clockwise collective-rotation noise on the security of quantum key distribution have been reported in Refs. [54] and [55], respectively. We analyze the effect of clockwise collective-rotation noise in the channel represented by the following unitary rotation matrix:…”

We investigate the effect of collective-rotation noise on the security of the six-state quantum key distribution. We study the case where the eavesdropper, Eve, performs an intercept-resend attack on the quantum communication between Alice, the sender, and Bob, the receiver. We first derive the collective-rotation noise model for the six-state protocol and then parameterize the mutual information between Alice and Eve. We then derive quantum bit error rate for three interceptresend attack scenarios. We observe that the six-state protocol is robust against intercept-resend attacks on collective rotation noise channels when the rotation angle is kept within certain bounds.

“…Additionally, using the Bell states, Yu (2015) proposed a scheme for quantum-secure direct dialogue protocols, adapted to both collective-dephasing noise and collective-rotation noise [50]. Furthermore, Jian et al [51] presented the security proof of the SARG04 protocol under collective-rotation noise and established that the protocol was secure against a certain level of such noise. Then, Wu and Chen (2015) analyzed a multi-photon analysis for the three-stage quantum protocol under the collective-rotation noise model and demonstrated that a multi-photon system provides better error rate tolerance during transmission in a noisy environment [52].…”

The security analysis of the Ekert 1991 (E91), Bennett 1992 (B92), six-state protocol, Scarani–Acín–Ribordy–Gisin 2004 (SARG04) quantum key distribution (QKD) protocols, and their variants have been studied in the presence of collective-rotation noise channels. However, besides the Bennett–Brassard 1984 (BB84) being the first proposed, extensively studied, and essential protocol, its security proof under collective-rotation noise is still missing. Thus, we aim to close this gap in the literature. Consequently, we investigate how collective-rotation noise channels affect the security of the BB84 protocol. Mainly, we study scenarios where the eavesdropper, Eve, conducts an intercept-resend attack on the transmitted photons sent via a quantum communication channel shared by Alice and Bob. Notably, we distinguish the impact of collective-rotation noise and that of the eavesdropper. To achieve this, we provide rigorous, yet straightforward numerical calculations. First, we derive a model for the collective-rotation noise for the BB84 protocol and parametrize the mutual information shared between Alice and Eve. This is followed by deriving the quantum bit error rate (QBER) for two intercept-resend attack scenarios. In particular, we demonstrate that, for small rotation angles, one can extract a secure secret key under a collective-rotation noise channel when there is no eavesdropping. We observe that noise induced by rotation of 0.35 radians of the prepared quantum state results in a QBER of 11%, which corresponds to the lower bound on the tolerable error rate for the BB84 QKD protocol against general attacks. Moreover, a rotational angle of 0.53 radians yields a 25% QBER, which corresponds to the error rate bound due to the intercept-resend attack. Finally, we conclude that the BB84 protocol is robust against intercept-resend attacks on collective-rotation noise channels when the rotation angle is varied arbitrarily within particular bounds.

“…Quantum key distribution (QKD) [1] is theoretically proven to be one key distribution method which can provide secret keys for remote communication parties with unconditional security, and many QKD schemes have been proposed to operate by a variety of protocols over optical fibers or free space [2−6] . However, in practical systems, quantum states during the process of preparation, transmission and detection may be affected by physical noises, eavesdroppers' attacks [7] and other factors resulting in error bits [8−10] . In order to obtain a consistent secret key string for both parties, says Alice and Bob, QKD requires them to interact with each other via a classical channel to perform a series of post-processing operations on the original key bits which have been transmitted through the quantum channel.…”
