OKI Develops Entangled Light Source

Facebook X LinkedIn Email
TOKYO, Feb. 21, 2012 — OKI Electric Industry announced that it has developed a quantum entangled light source that offers the highest purity level achieved to date. OKI has successfully developed a quantum entangled light source based on cascaded nonlinear optical effects using a proprietary periodically poled lithium niobate ridge-waveguide device operating at room temperature. Research led by professor Shuichiro Inoue at the Institute of Quantum Science at Nihon University confirms a signal-to-noise ratio more than 100-fold better than that of optical fiber light sources. These tests show that the...Read full article
