Today, his dream is a reality in laboratories around the world. This has become possible by using complex experimental setups of thousands of optical elements, which allow atoms to be cooled to Nanokelvin temperatures, where they almost come to rest. In my talk I will discuss the applications for quantum simulation using neutral atoms and discuss selected application highlights in science. I will discuss the status of the field and give an outlook on future scalability of the different underlying systems. Speaker: Prof. Immanuel Bloch (LMU &amp; MPQ) Bio: Immanuel Bloch is scientific director at the Max-Planck-Institute of Quantum Optics, Garching and professor for experimental physics at the Ludwig-Maximilians University (LMU) in Munich. He is also one of the spokespersons of the Munich Center for Quantum Science and Technology (MCQST). Immanuel Bloch obtained his PhD in physics in 2000 from LMU. From 2003-2009 he was full professor at the University of Mainz. In 2009 he returned to Munich, where his research focus lies on the investigation of quantum many-body systems, quantum simulations, quantum information processing and quantum optics. Immanuel Bloch received several prizes for his work, among them the Gottfried-Wilhelm-Leibniz prize of the German Science Foundation (DFG), the German National Merit Medal in 2005, the international commission of optics prize, the Senior Prize for Fundamental Aspects of Quantum Electronics and Optics of the European Physical Society, the Körber European Science Prize, the Senior BEC Award and the Harvey Prize of the Technion.2nd lecture: Title: Many-body physics with quantum simulators based on arrays of individual atoms This talk will present our effort at the Institut d’Optique to develop quantum simulators based on arrays of individual atoms. These simulators rely on the dipole-dipole interactions between cold atoms in order to implement spin Hamiltonians useful for quantum simulation of condensed matter or quantum optics situations. We trap individual atoms in arrays of optical tweezers separated by a few micrometers. We create almost arbitrary geometries of the atomic arrays in two and three dimensions up to about 200 atoms. To make the atoms interact, we either excite them to Rydberg states or induce optical dipoles with a near-resonance laser. Using this platform, we have in particular explored quantum magnetism, topological synthetic quantum matter, and a new light-matter interface. Speaker: Prof. Antoine Browaeys (SCO Pasqal, senior staff Scientist at CNRS)3rd lecture:Title: Quantum metrology with optical tweezer arrays of neutral atoms Quantum science with neutral atoms has exhibited great advances in the past two decades. Many of these advances follow from the development of new techniques for cooling, trapping, and controlling atomic samples. As one example, the technique of optical tweezer trapping of neutral atom arrays has been a powerful tool for quantum simulation and quantum information, because it naturally allows control and detection of individual atoms while also incorporating interactions, such as through Rydberg excitation or collisions. In this talk, I will describe ongoing work at JILA where we have explored a new direction for the tweezer platform: quantum metrology. I will report our recent progress towards combining scalability and quantum coherence in a tweezer-based clock system, and our efforts towards using quantum information concepts to create entangled states that enhance metrological performance. Speaker: Prof. Adam Kaufman (University of Colorado Boulder)Bio: Adam Kaufman is an associate JILA fellow and assistant professor adjoint at CU Boulder. 4th lecture:Title: Individual control of nuclear spin qubits in an array of neutral strontium atomsDue to incredible advancements in optical trapping and manipulation of individual atoms, ultracold neutral atoms have emerged as a promising platform for scalable quantum computation. Universal single-qubit control requires high quality state preparation, spatially resolved manipulation, and projective readout of each qubit. For state preparation and readout, neutral atom platforms can apply techniques commonly used in quantum gas microscopes and single-atom trapping machines. Furthermore, the ability to isolate the internal spin states of individual neutral atoms from both external fields and neighboring atoms allows for seconds-scale coherence times. In this talk, I will discuss the efforts at Atom Computing to trap and manipulate an array of neutral strontium atoms, focusing on the tools necessary to measure the state of our nuclear spin qubits and to drive single-qubit rotations in the array.Speaker: Dr. Brian Lester (Atom Computing)Bio: Brian Lester is a Senior Quantum Engineer at Atom Computing, Inc. Brian earned his PhD in 2016 for work trapping and manipulating individual ground-state atoms in Cindy Regal’s group at JILA. Prior to joining Atom in 2018, he was a postdoctoral researcher working with 3D circuit quantum electrodynamics (cQED) systems in Rob Schoelkopf’s group at Yale. 5th lecture:Title: New Technology for Programmable Quantum Simulators of Neutral AtomsQuantum systems built from neutral atoms have enjoyed wide success as quantum simulators for many years, providing a versatile platform to probe novel effects of many-body quantum systems at large scales. Recent breakthroughs in the use of on-demand long-range Rydberg interactions and versatile optical tweezer manipulation have now demonstrated highly programmable simulators, rapidly showing new capabilities to study large-scale quantum dynamics, quantum phases and a range of new phenomena. With sustained engineering effort devoted to further increasing the scale and programmability of coherent manipulation in these systems, it is very possible that neutral atom simulators will play a leading role for generalized quantum computation in coming years. I will describe efforts at QuEra Computing, a recent startup founded by leaders in the field of neutral atom quantum simulation, quantum information science and photonic engineering, to bring this technology to commercial maturity, spanning challenges from expanding the boundaries of achievable hardware to determining the first problems on which these systems are likely to provide calculational advantage.Speaker: Nate Gemelke (CTO Quera) Bio: Dr. Nate Gemelke is currently the CTO of QuEra Computing, Inc, and has worked with neutral atom quantum systems for over 20 years, starting with his PhD work performing early quantum simulations with neutral atoms with Steven Chu at Stanford University and later with Cheng Chin at the University of Chicago. Prior to joining QuEra, he was an Assistant Professor of Physics at Penn State University where his research centered on simulating topological phases of matter with neutral atoms.
