Polish research in 2D layered material opens up a new path to build quantum chips

Polish scientists at the University of Warsaw discovered that a thin 2D material called ZnPS3 can emit single photons, a key requirement for building quantum chips. When hit with a laser, defects in the material's crystal structure released highly polarized photons — useful for quantum cryptography. Unlike diamonds, this 2D material can integrate easily into silicon chips at room temperature, making scalable quantum computing more realistic.
