Scientists harness vacuum fluctuations to engineer quantum materials

Researchers have developed a new optical cavity design that selectively enhances quantum vacuum fluctuations of circularly polarized light in one direction, achieving chirality without strong magnetic fields. The team used lightly doped indium antimonide to construct the cavity, which can transform materials placed inside it. Simulations predict that graphene in this cavity would become a special insulator useful for quantum computing. This breakthrough opens up possibilities for controlling material properties and developing novel quantum technologies using subtle vacuum effects.
