Dept.\, guest speaker/nano devices Thurs\, Nov 20\n\n We study the coherent dynamics of a double quantum dot (DQD) system—two tiny semiconductor “boxes” that can each hold a single electron—embe dded in the channel of a field-effect transistor. When one electron is sha red between the two dots\, the system can form a Bell state\, a special ty pe of quantum entanglement where the electron has no definite location but exists as a superposition of being in either dot. We model how this entan gled state evolves in time when the two dots are tunnel-coupled to each ot her and also connected to Majorana zero modes (MZMs) located at the ends o f a topological superconducting nanowire.\n\nOur simulations show oscillat ory exchange of population between the two dots and long-lived coherence e ven when the MZMs are strongly coupled. A small portion of the amplitude l eaks into the Majorana channel\, but instead of destroying entanglement\, it shares coherence between the DQD and the MZMs. These results point to n ew ways of protecting and controlling quantum information in solid-state d evices.\n\nRoom: 334\, Bldg: LSC\, Loyola Science Center\, University of S cranton\, University of Scranton\, 204 Monroe Ave\, Scranton\, Pennsylvan ia\, United States\, 18510\, Virtual: https://events.vtools.ieee.org/m/502 980 LOCATION:Room: 334\, Bldg: LSC\, Loyola Science Center\, University of Scra nton\, University of Scranton\, 204 Monroe Ave\, Scranton\, Pennsylvania\ , United States\, 18510\, Virtual: https://events.vtools.ieee.org/m/502980 ORGANIZER:james.omalley2@scranton.edu SEQUENCE:7 SUMMARY: ELECTRON DEVICES SOCIETY (IEEE-EDS) ACTIVITIES Dr. Varonides & stu dents\, Phys/Eng.
