Abstract: In this talk, I will present our recent theoretical studies of the nonequilibrium quantum dynamics of single electrons in quantum liquid and solid helium, as well as the new quantum electronic structures and optical behaviors at the interface of solid neon and liquid helium. I will also present our on-chip experimental design to use these trapped electrons as reconfigurable long-spin-coherence qubits and our preliminary experimental effort along this direction using our new optical dilution-fridge system.
