“…It has outstanding advantages. For example, MDI-QKD is easy to implement [ 176 ]. It also allows cost-effective multiuser-integrated systems, in which users only pay for low-cost transmitter chips while sharing the expensive devices (e.g., SNSPDs) among many users in a public, untrusted relay.…”

Quantum key distribution (QKD), guaranteed by the principles of quantum mechanics, is one of the most promising solutions for the future of secure communication. Integrated quantum photonics provides a stable, compact, and robust platform for the implementation of complex photonic circuits amenable to mass manufacture, and also allows for the generation, detection, and processing of quantum states of light at a growing system’s scale, functionality, and complexity. Integrated quantum photonics provides a compelling technology for the integration of QKD systems. In this review, we summarize the advances in integrated QKD systems, including integrated photon sources, detectors, and encoding and decoding components for QKD implements. Complete demonstrations of various QKD schemes based on integrated photonic chips are also discussed.

Voting is one of the most prominent components of democracy. The one-vote veto, which requires the voting result to be only "yes" or "no", is a particularly noteworthy type of voting with widespread application. When obtaining a "no" result, no useful information about the number of "no" votes and who votes "no" is disclosed. In this paper, we introduce a protocol for anonymous one-vote veto utilizing qubits and local Pauli operations Z and X, building simple processes for easy implementation under the current technology. For better elaboration, we give two examples: all voters cast "yes" votes and only one voter casts a "no." Then, the corresponding experiment tests are conducted on the simulated IBM quantum computer to verify their feasibility. We also show that the proposed protocol has the desirable properties of privacy, fairness, verifiability and robustness. Furthermore, we analyze the proposed protocol's security against cheating from eavesdroppers, a semi-honest server and malicious voters. This work is the first attempt to illustrate how qubits can be useful for building a secure anonymous one-vote veto strategy.

“…Quantum entanglement [1] has been considered as an essential asset to quantum communication and computation tasks. Bell states analysis (BSA), which is defined as the projection of two qubits onto maximally entangled states, is a crucial element in many important quantum information processing tasks, including measurement-based quantum computation [2,3], quantum teleportation [4,5], entanglement swapping [6,7], quantum dense coding [8][9][10], quantum key distribution [11][12][13][14][15][16][17], entanglement concentration [18][19][20], and quantum secure direct communication [21][22][23][24][25][26][27]. However, it is fail to unambiguously discriminate all of the four single degree of freedom (DOF) shared Bell states with only linear optical elements [28,29], which is called a complete linear optical BSA for photonic system.…”

Hyperentangled Bell states analysis (HBSA) is an essential building block for certain hyper-parallel quantum information processing. We propose a complete and deterministic HBSA scheme encoded in spatial and polarization degrees of freedom (DOFs) of two-photon system assisted by a fixed frequency-based entanglement and a time interval DOF. The parity information the spatial-based and polarization-based hyper-entanglement can be distinguished by the distinct time intervals of the photon pairs, and the phase information can be distinguished by the detection signature. Compared with previous schemes, the number of the auxiliary entanglements is reduced from two to one by introducing time interval DOF. Moreover, the additional frequency and time interval DOFs suffer less from the collective channel noise.
