But a contemporary technological challenge: faster electro-optic modulators are expensive and often require very customized engineering. To add to that, it may not be very efficient, which introduces unwanted losses in the system.<\/p>\n<p>Nature Publishing: <a href=\"https:\/\/www.nature.com\/articles\/s41534-025-01083-0\">https:\/\/www.nature.com\/articles\/s41534-025-01083-0<\/a><\/p>\n<p>Security wise: The team\u2019s work combines years of research in quantum optics, semiconductor physics, and photonic engineering to open the door for next-generation quantum computers andunwanted losses in the system.<\/p>\n<p>Communications.
