“…In this paper, we mainly discuss two kinds of collective noise: collective-dephasing noise and collective-rotation noise [27][28][29][30][31][32][33][34][35][36][37][38]. Next, we give the changes of qubits |0〉 and |1〉 in Z basis when they pass through two kinds of collective noises, respectively.…”

“…In 2020, Zhou et al [34] proposed a two-party QKA protocol based on entanglement swapping and GHZ states, which can resist collective noise. In the same year, Tang et al [35] realized the protocol of both parties to resist collective noise by constructing a 7-particle state. In 2022, Guo et al [36] proposed a QKA protocol against collective noise based on the measured correlation of logical GHZ states.…”

Quantum key agreement (QKA) is an important branch of quantum cryptography. Particles are easily affected by noise in quantum channel transmission, which provides a cover for eavesdropper Eve to attack maliciously and eventually leads to the failure of protocol. In this paper, based on the properties of four-particle cluster states and their entanglement swapping, two authenticated two-party QKA protocols that can resist collective noise (collective-dephasing noise and collective-rotation noise) by using CZ, CNOT, and Pauli operations are designed, respectively. Besides, both parties can authenticate each other’s identities, which makes our protocol more secure. In addition, security analysis shows that these two protocols can resist various attacks from inside and outside, such as participant attacks and entangle-measure attacks.

Quantum direct communication (QDC) uses the basic principle of quantum mechanics to realize the secure communication between legal parties. Deterministic secure quantum communication (DSQC), as a branch of QDC, is a way to transmit secret message with the aid of classical bits. In this paper, a multi-party DSQC based on [Formula: see text]-dimension [Formula: see text]-particles GHZ states is proposed, in which unitary operation is not required. On the basis of [Formula: see text]-dimension single-photon measurement results, the communication parties encode and decode the message through performing modulo addition and subtraction. In addition, the scheme uses the added [Formula: see text]-dimension single photon for eavesdropping detection. The scheme has expansibility and universality. It can scale to as many parties in any dimension as required. Based on the star-shaped communication structure, it can be extended to a network to achieve the rapid communication of secret message across regions.
