PME Quantum Seminar - Dafei Jin

Nonpolar atoms and molecules with small mass and weak interaction, such as helium, neon, and hydrogen, form condensed quantum liquids and solids at low temperatures. They are among the purest matter in nature, free of chemical contamination, dangling bonds, or two-level fluctuators, and can serve as ideal hosts for quantum information carriers. In this talk, I will present our recent development of new solidstate qubits based upon single electrons trapped on the surfaces of solid neon and solid hydrogen that are embedded in superconducting quantum microwave circuits. The measured coherence time of electron-on-neon (eNe) and electron-on-hydrogen (eH2) charge qubits have reached ~100us and ~10us, respectively, significantly longer than conventional superconducting and semiconducting charge qubits. Their noise spectrum and temperature dependence also indicate their promising candidacy for large-scale quantum computing. Finally, I will present our ongoing effort to deterministically trap atoms and ions in quantum solids for potential applications in quantum networking.
