In this talk, I will describe two approaches we are pursuing to generate fast and high-fidelity remote entanglement. In the first approach, we have demonstrated a photonic interconnect based on high-fidelity entanglement of the metastable nuclear spin-1\/2 qubit in ytterbium-171 and a telecom-band photon with time-bin encoding. We have realized an atom-photon Bell state fidelity of 0.95 when correcting for atomic measurement errors. As an extension of this work, I will describe a second system based on ytterbium-171 atom arrays in a near-concentric optical cavity. We anticipate the ability to generate atom-atom Bell pairs with fidelity approaching 0.99 and rate of 10^4 ebits\/sec using this telecom photonic interface. In the second approach, I will introduce a novel technique for transporting large tweezer arrays over 200 mm within a single vacuum chamber via a microscope objective mounted on an air-bearing linear motion stage. I will describe our vision for modular quantum computation based on an array of atom arrays.\r\n\r\nBio: Prof. Covey\u2019s research utilizes arrays of individually controlled neutral alkaline-earth atoms in optical tweezers to engineer many-body entangled states. Applications of interest include distributed quantum computing, quantum communication, and quantum-enhanced metrology with atomic array optical clocks. He received his Ph.D. in Physics from the University of Colorado-Boulder.", "occurrence_notes":"https:\/\/umich.zoom.us\/j\/99940829961?jst=2", "guid":"142258-21890278@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/142258", "building_id":"1000404", "building_name":"Michigan Memorial Phoenix Project", "campus_maps_id":"60", "room":"PML2000", "location_name":"Michigan Memorial Phoenix Project", "has_livestream":1, "livestream_type":"zoom", "livetream_require_login":0, "livestream_id":"999408299612", "livestream_link":"https:\/\/umich.zoom.us\/j\/999408299612", "cost":"", "tags":["Astronomy","Quantum Science","Quantum Computing","Quantum","Physics","Electrical Engineering And Computer Science","Electrical And Computer Engineering","Computer Science And Engineering","Chemistry"], "website":"", "sponsors":[ { "group_name":"Quantum Research Institute", "group_id":"5043", "website":"" }, { "group_name":"Department of Physics", "group_id":"1965", "website":"" }, { "group_name":"Electrical and Computer Engineering", "group_id":"3153", "website":"http:\/\/www.ece.engin.umich.edu" }, { "group_name":"Computer Science and Engineering Division", "group_id":"3197", "website":"http:\/\/cse.umich.edu" }, { "group_name":"Applied Physics", "group_id":"3606", "website":"" }, { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" }, { "group_name":"Materials Science and Engineering", "group_id":"3942", "website":"" }, { "group_name":"Quantum Research Institute", "group_id":"5034", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/01\/event_142258_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_142258_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21890278 } , "145393-21897232": { "datetime_modified":"20260213T101444", "datetime_start":"20260226T110000", "datetime_end":"20260226T180000", "has_end_time":1, "date_start":"2026-02-26", "date_end":"2026-02-26", "time_start":"11:00:00", "time_end":"18:00:00", "time_zone":"America\/Detroit", "event_title":"Teach Access Student Academy", "occurrence_title":"", "combined_title":"Teach Access Student Academy", "event_subtitle":"", "event_type":"Conference \/ Symposium", "event_type_id":"5", "description":"Discover how to build empathy and awareness for accessibility in this engaging, interactive event!
