DESCRIPTION:Speakers: Chao-Yang Lu (the University of Science and Technolo
 gy of China)\n\nHost: Prof. Hong Ding (丁洪)\nAbstract:I will go through
  our recent efforts in my group using photons and atoms to build increasin
 gly large-scale quantum computers and\, in turn\, how these early quantum 
 computers can already be used for studies of fundamental problems in mathe
 matics\, quantum physics\, and condensed matter physics. We use the protoc
 ol of Gaussian boson sampling to demonstrate quantum computational advanta
 ge\, with up to 3050 detected photons. We develop an AI-enabled constant-t
 ime-overhead rearrangement protocol to prepare a 2024 defect-free atomic a
 rray. Using a single atom trapped in an optical tweezer and cooled to the 
 motional ground state in three dimensions\, we faithfully realize the Eins
 tein-Bohr recoiling-slit gedankenexperiment tunable at the quantum limit. 
 Based on a bottom-up quantum engineering approach\, we experimentally crea
 ted the fractional quantum Hall state using strongly interacting photons. 
 We further use the quantum computing platform to rule out a real-value des
 cription of standard formalism of quantum theory.\nBio:Chao-Yang Lu\, Chai
