Story summary

Interuniversity Microelectronics Centre (imec) and Stanford University engineered thin-film strontium titanate (SrTiO3) to achieve record electro-optic performance at cryogenic temperatures.
The material exhibits a Pockels coefficient of nearly 350 pm/V at 4 K.
The study, published in Science, highlights SrTiO3's potential for compact, low-loss electro-optic components used in quantum interconnects and photonic chips.
Funding from Samsung and Google supports the work, aiming to enhance quantum computing capabilities.
