This breakthrough in optical control systems enables dynamic manipulation of ultracold atoms at record speeds, directly advancing programmable quantum simulators and Hubbard models. By achieving high-resolution patterning with minimal disturbance, this development addresses critical challenges in scaling quantum hardware for complex physics simulations. The technology represents a significant leap forward in the practical implementation of atom-based quantum architectures.
Harvard University Builds Atom Array Control at 84 MFPS
Optical systems now redraw atom arrays at rates exceeding 84 megapframes per second, alongside an intensity resolution of one part in a thousand. This surpasses existing technologies limited to kilohertz or tens of kilohertz frame rates, enabling dynamic manipulation previously unattainable. Such precise and rapid patterning unlocks fully programmable Hubbard models with time-dependent control over atomic interactions.
Exceeding 84 megaprames per second, a new optical system controls ultracold atoms representing a sharp leap in speed and resolution. Alexander Dennisovich Deters from Harvard University and colleagues developed a dispersive spatial light modulator, a device which shapes light to manipulate the atoms, achieving this record frame rate alongside an intensity resolution of 10-3. This system manipulates ultracold atoms at speeds exceeding eighty-four million frames per second. It precisely controls atom arrangement through dispersive spatial light modulation mapping frequency to position in two dimensions. The capability…
