Quantum communication networks are crucial for both secure and cryptographic networked tasks. Building quantum in a scalable cost-effective way is essential their widespread adoption. Here, we establish complete polarization entanglement–based fully connected network, which features an ultrabright integrated Bragg reflection waveguide source, managed by untrusted service provider, streamlined analysis module, requires only one single-photon detector each user. We perform continuously working...
Building communication links among multiple users in a scalable and robust way is key objective achieving large-scale quantum networks. In realistic scenario, noise from the coexisting classical light inevitable can ultimately disrupt entanglement. The previous significant fully connected multiuser entanglement distribution experiments are conducted using dark fiber there no explicit relation between degradations induced by its error rate. Here we fabricate semiconductor chip with high...
Quantum entanglement is a vital resource in quantum information processing. High-dimensional offers advantages that classical systems cannot surpass, particularly enhancing channel capacity, improving system noise resilience, and increasing sensitivity to external environments. The construction of multimode the spectral domain well-suited for fiber-optic systems. Here, we present straightforward scheme generating frequency-bin using semiconductor chip through simple mode conversion. A...
Entangled photons are important for testing foundations of quantum physics and at the heart technology.
