Quantum networks, systems that connect devices using quantum mechanical effects, could potentially allow users to share information more securely and efficiently. Building these networks typically entails linking stationary qubits, units of quantum information encoded in trapped ions or other physical systems, using photons (particles of light) transmitted through optical fibers.<\/p>\n
One challenge when trying to realize quantum networks is that some physical systems that serve as qubits emit ultraviolet light, electromagnetic radiation with wavelengths ranging from approximately 100 to 400 nanometers. This is problematic because optical fibers, the thin light-guiding strands used to link quantum devices, are known to transmit light at these wavelengths poorly.<\/p>\n
Researchers at the University of Science and Technology of China, Jinan Institute of Quantum Technology and other institutions recently developed a new converter that could help to bridge the gap between the ultraviolet light emitted by these systems and the light wavelengths transmitted with fewer losses through optical fibers. Their device, introduced in a paper published<\/a> in Physical Review Letters<\/i>, relies on thin-film lithium niobate, a crystalline material that enables interactions between light waves with different wavelengths, patterned into a structure that confines and directs light.<\/p>\n","protected":false},"excerpt":{"rendered":" Quantum networks, systems that connect devices using quantum mechanical effects, could potentially allow users to share information more securely and efficiently.
