Join us in person at Rackham Amphitheatre (4th Floor) or via livestream: https:\/\/myumi.ch\/d8Q7X\n\nIn the span of four decades, quantum computation has evolved from an intellectual curiosity to a potentially realizable technology. I will describe my thesis work on macroscopic quantum tunneling and energy-level quantization that led to the Nobel Prize, as well as several other important experiments that advanced superconducting qubits. Nevertheless, the path toward a full-stack scalable technology is a work in progress. There are significant outstanding quantum hardware, fabrication, architecture, and algorithmic challenges that must be solved. Here, we show how the road to scaling could be paved by adopting existing semiconductor technology to build much higher-quality qubits and employing system engineering approaches.", "occurrence_notes":null, "guid":"148343-21903967@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148343", "building_id":"1000172", "building_name":"Rackham Graduate School (Horace H.)", "campus_maps_id":"71", "room":"4th Floor Amphitheatre", "location_name":"Rackham Graduate School (Horace H.)", "has_livestream":0, "cost":"", "tags":["Graduate Students","Undergraduate Students","Faculty","Undergrad Physics Events","Smoke-free","Physics"], "website":"https:\/\/lsa.umich.edu\/physics\/news-events\/special-lectures\/ta-you-wu-lecture.html", "sponsors":[ { "group_name":"Department Colloquia", "group_id":"3804", "website":"" }, { "group_name":"Department of Astronomy", "group_id":"1178", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" }, { "group_name":"The Center for the Study of Complex Systems", "group_id":"3247", "website":"https:\/\/lsa.umich.edu\/cscs\/" }, { "group_name":"Department of Statistics", "group_id":"3473", "website":"" }, { "group_name":"Applied Physics", "group_id":"3606", "website":"" }, { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" }, { "group_name":"LSA Biophysics", "group_id":"3767", "website":"" }, { "group_name":"Astronomy Colloquia", "group_id":"3797", "website":"" }, { "group_name":"Leinweber Institute for Theoretical Physics Seminars", "group_id":"4311", "website":"" }, { "group_name":"Undergrad Physics Events", "group_id":"4397", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/09\/event_148343_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/09\/event_148343_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/09\/event_148343_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/09\/event_148343_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/09\/event_148343_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/09\/event_148343_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/09\/event_148343_original-1.png" }, "occurrence_count":1, "first_occurrence":21903967 } }
