The Fraunhofer Institute for Photonic Microsystems IPMS and the Max Planck Institute of Quantum Optics (MPQ) have achieved groundbreaking results in generating arbitrary light distributions. These findings are also relevant to atomic quantum computing. Spatial light modulators can be used to hold a large number of atoms in desired positions at the same time via laser beam. Localized in this way, they become switchable information carriers for quantum computers or for other applications in quantum metrology and quantum simulation, marking a major stride toward scalable quantum systems.
