A University of Oklahoma-led group of physicists believes chip-based atomic production binds guarantee to make a second quantum revolution—the engineering of quantum matter with capricious precision—a reality. With new technological advances in phony and trapping, hybrid quantum systems are rising as ideal platforms for a different operation of studies in quantum control, quantum make-believe and computing.
James P. Shaffer, highbrow in a Homer L. Dodge Department of Physics and Astronomy, OU College of Arts and Sciences; Jon Sedlacek, OU connoisseur student; and a group from a University of Nevada, Western Washington University, The United States Naval Academy, Sandia National Laboratories and Harvard-Smithsonian Center for Astrophysics, have published investigate critical for integrating Rydberg atoms into hybrid quantum systems and a elemental investigate of atom-surface interactions, as good as applications for electrons firm to a 2D surface.
“A available aspect for focus in hybrid quantum systems is quartz since of a endless use in a semiconductor and optics industries,” Sedlacek said. “The aspect has been a theme of new seductiveness as a outcome of it fortitude and low aspect energy. Mitigating electric fields nearby ‘trapping’ surfaces is a holy grail for realizing hybrid quantum systems,” combined Hossein Sadeghpour, executive of a Institute for Theoretical Atomic Molecular and Optical Physics, Harvard-Smithsonian Center for Astrophysics.
In this work, Shaffer finds ionized electrons from Rydberg atoms vehement nearby a quartz aspect form a 2D covering of electrons above a surface, canceling a electric margin constructed by rubidium aspect adsorbates. The complement is identical to nucleus trapping in a 2D gas on superfluid glass helium. The contracting of electrons to a aspect almost reduces a electric margin above a surface.
“Our formula uncover that contracting is due to a picture intensity of a nucleus inside a quartz,” pronounced Shaffer. “The nucleus can’t disband into a quartz since a rubidium adsorbates make a aspect have a disastrous nucleus affinity. The proceed is a earnest pathway for coupling Rydberg atoms to surfaces as good as for regulating surfaces tighten to atomic and ionic samples.”
A paper on this investigate was published in a American Physics Society’s Physical Review Letters. The OU partial of this work was upheld by a Defense Advanced Research Projects Agency Quasar module by a extend by a Army Research Office, a Air Force Office of Scientific Research and a National Science Foundation.
