Secure Internet transmission with Quantum Light

Caption

This greatly enlarged artist's rendering shows a gallium arsenide chip. The pink vector (below) depicts "classical" or laser light entering the chip. The blue structure in the center is indium arsenide. This material acts like a special filter that allows classical light to pass through while also generating quantum light, shown in blue, that provides a secure way to transmit data.
