Researchers have achieved 99% indistinguishable photon generation using continuous-wave driven integrated chips, overturning theoretical limits that previously suggested near-zero performance for this configuration. By combining finite-time detection with cavity-enhanced spontaneous four-wave mixing, the team enables high-fidelity quantum communication networks without requiring pulsed lasers or complex external setups. This advancement significantly improves the scalability and practicality of on-chip quantum light sources for future quantum internet infrastructure.
Researchers Attain 99% Indistinguishable Photons from Chips
Hong, Ou, Mandel interference approaching unity is now attainable from continuous-wave driven integrated devices, defying prior theoretical limits derived from joint spectral amplitude calculations. Measurements reveal HOM visibilities of 0. 992±0.
A Hong, Ou, Mandel (HOM) interference visibility of nine hundred and ninety-two point zero plus or minus eight tenths of one percent has been achieved at the University of Science and Technology of China and collaborating institutions. Conventional methods predicted near-zero visibility for photons generated using continuous-wave driven microresonators due to limitations imposed by the joint spectral amplitude; however, finite-time detection combined with cavity-enhanced spontaneous four-wave mixing overcomes these bounds. The team establishes a new approach to generating…
