We report the first experimental demonstration of quantum entanglement among ten
spatially separated single photons. A near-optimal entangled photon-pair source was …

We propose a conceptual design for a quantum blockchain. Our method involves encoding
the blockchain into a temporal GHZ (Greenberger–Horne–Zeilinger) state of photons that do …

Blockchain technology has gained significant prominence in recent years due to its public,
distributed, and decentration characteristics, which was widely applied in all walks of life …

The role of the timing and order of quantum measurements is not just a fundamental
question of quantum mechanics, but also a puzzling one. Any part of a quantum system that …

The decoherence-free subspace (DFS) serves as a protective shield against certain types of
environmental noise, allowing the system to remain coherent for extended periods of time. In …

Quantum blockchain can be understood as a decentralized, encrypted and distributed
database based on quantum computation and quantum information theory. Once the data is …

Large-scale quantum entanglement endows quantum technologies with significant quantum
advantages over their classical counterparts. Nevertheless, this power is rarely unleashed …

Quantum entanglement plays a crucial role in quantum information technologies. In the
paper, we propose two schemes to convert from two-photon Knill–Laflamme–Milburn (KLM) …

Web 3.0 pursues the establishment of decentralized ecosystems based on blockchain
technologies to drive the digital transformation of physical commerce and governance …

Multiphoton entangled quantum states are key to advancing quantum technologies such as
multiparty quantum communications, quantum sensing, or quantum computation. Their …
