Summary:
UCLA researchers in the Department of Electrical and Computer Engineering have developed a multiparty network for improved quantum communications.
Background:
Fully secure quantum networks are essential in achieving efficient and rapid quantum computing. These networks connect distant quantum computers and increase the computational volume that is distributed. Existing technologies suffer from rate limitations and low efficiencies. Cost, material, and equipment issues further limit the widespread use of these networks. There remains an unmet need for a scalable quantum network with higher information capacity, robustness, and enhanced security.
Innovation:
UCLA researchers in the Department of Electrical and Computer Engineering developed a scalable quantum network with high-dimensional entanglement. This system allows for higher information capacity with reduced errors over long distances. An additional module allows for channel security monitoring. The use of wavelength and time-division multiplexing gives rise to a scalable quantum network with a reduced number of required channels and equipment per user. This technology significantly improves rates and reduces equipment demands to a single unit per user.
