Clark<\/strong><strong><\/strong><\/h5>\n<h4><\/h4>\n<p style=\"font-size: 12px\">Quantum process tomography is crucial for understanding quantum channels and characterizing properties of quantum devices. Inspired by recent advances using classical shadows in quantum state tomography, we have developed a classical shadow method for quantum process tomography, ShadowQPT. We have proved rigorous measurement complexity for ShadowQPT and provided new post-processing techniques for improving the accuracy. Furthermore, our approach has been implemented on the IonQ trapped ion quantum computer doing reconstructions for unitary and non-unitary processes of a channel of up to n=4 qubits (equivalent to the complexity of n=8 qubits in state tomography) as well as determining input-output state overlaps. We show that ShadowQPT is efficient and provides new advancement on quantum process tomography in near-term and future quantum devices.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"font-size: 12px\">Funding Sources: NSF Quantum Leap Challenge Institute for Hybrid Quantum Architectures and Networks (NSF Award 2016136)|National Science Foundation under Cooperative Agreement PHY-2019786<\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/cqe.mit.edu\/quarc2022\/wp-content\/uploads\/sites\/3\/2021\/12\/Screenshot-from-2021-12-16-21-50-20-benchmark.png&#8221; title_text=&#8221;Screenshot-from-2021-12-16-21-50-20-benchmark&#8221; align=&#8221;center&#8221; align_tablet=&#8221;center&#8221; align_phone=&#8221;center&#8221; align_last_edited=&#8221;on|desktop&#8221; _builder_version=&#8221;4.12.1&#8243; max_width=&#8221;100%&#8221; module_alignment=&#8221;center&#8221; custom_margin=&#8221;||||false|false&#8221; animation_style=&#8221;slide&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=&#8221;1_2,1_2&#8243; use_custom_gutter=&#8221;on&#8221; gutter_width=&#8221;1&#8243; _builder_version=&#8221;4.12.1&#8243; background_color=&#8221;#FFFFFF&#8221; width=&#8221;100%&#8221; max_width=&#8221;75%&#8221; module_alignment=&#8221;center&#8221; custom_padding=&#8221;5%|5%|5%|5%|true|false&#8221; use_custom_width=&#8221;on&#8221; width_unit=&#8221;off&#8221; custom_width_percent=&#8221;100%&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;3.25&#8243; custom_padding=&#8221;15%|||&#8221; custom_padding_tablet=&#8221;0px|||&#8221; custom_padding_phone=&#8221;0px|||&#8221; custom_padding_last_edited=&#8221;on|tablet&#8221; global_colors_info=&#8221;{}&#8221; padding_tablet=&#8221;0px|||&#8221; padding_last_edited=&#8221;on|tablet&#8221; custom_padding__hover=&#8221;|||&#8221; padding_phone=&#8221;0px|||&#8221;][et_pb_text _builder_version=&#8221;4.12.1&#8243; text_font=&#8221;||||||||&#8221; text_font_size=&#8221;16px&#8221; text_line_height=&#8221;2em&#8221; header_font=&#8221;Ubuntu|700|||||||&#8221; header_font_size=&#8221;60px&#8221; header_line_height=&#8221;1.4em&#8221; header_3_font=&#8221;Ubuntu||||||||&#8221; header_3_line_height=&#8221;1.8em&#8221; header_6_font=&#8221;Lato|700|||||||&#8221; header_6_font_size=&#8221;18px&#8221; header_6_line_height=&#8221;1.8em&#8221; background_color=&#8221;#96a6bd&#8221; background_layout=&#8221;dark&#8221; custom_padding=&#8221;60px|10%|60px|10%|true|true&#8221; custom_padding_phone=&#8221;80px|2vw||2vw||true&#8221; custom_padding_last_edited=&#8221;off|desktop&#8221; animation_style=&#8221;slide&#8221; animation_direction=&#8221;top&#8221; animation_intensity_slide=&#8221;2%&#8221; text_font_size_tablet=&#8221;&#8221; text_font_size_phone=&#8221;14px&#8221; text_font_size_last_edited=&#8221;on|desktop&#8221; header_font_size_tablet=&#8221;&#8221; header_font_size_phone=&#8221;32px&#8221; header_font_size_last_edited=&#8221;on|desktop&#8221; custom_css_main_element=&#8221;display:flex;&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h1><strong>Di Luo<\/strong><\/h1>\n<p>&nbsp;<\/p>\n<h2><strong>Affiliation: MIT, Postdoc<\/strong><strong><\/strong><\/h2>\n<p>&nbsp;<\/p>\n<h2><strong>Areas of Research<\/strong><\/h2>\n<ul>\n<li style=\"list-style-type: none\">\n<ul>\n<li>Quantum Algorithms<\/li>\n<li>Atomic, Molecular, &amp; Optical Physics<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2><strong>Open to<\/strong><\/h2>\n<ul>\n<li style=\"list-style-type: none\">\n<ul>\n<li>Internships<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_2&#8243; _builder_version=&#8221;3.25&#8243; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; custom_padding__hover=&#8221;|||&#8221;][et_pb_image src=&#8221;https:\/\/cqe.mit.edu\/quarc2022\/wp-content\/uploads\/sites\/3\/2021\/12\/portrait_Di.jpg&#8221; title_text=&#8221;portrait_Di&#8221; align=&#8221;center&#8221; align_tablet=&#8221;center&#8221; align_phone=&#8221;center&#8221; align_last_edited=&#8221;on|desktop&#8221; _builder_version=&#8221;4.12.1&#8243; max_width=&#8221;95%&#8221; module_alignment=&#8221;center&#8221; animation_style=&#8221;slide&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Classical Shadows for Quantum Process Tomography on Near-term Quantum Computers Ryan Levy | Di Luo | Bryan K.
