DESCRIPTION:Abstract: A quantum compiler is one essential and critical com
 ponent in a quantum computing system to deploy and optimize the quantum p
 rograms onto the underlying physical quantum hardware platforms. Yet\, to
 day's quantum compilers are still far from optimal. One reason is that mo
 st optimizations in today's quantum compilers are local program transform
 ations over very few qubits and gates. In general\, it is highly non-triv
 ial for a compiler that runs on a classical computer to derive large-scal
 e program optimizations at the gate level automatically.\n\nIn this talk\
 , we will discuss how we can systematically enhance the quantum compilers
  by introducing high-level program optimizations in the quantum software/
 compiler infrastructure. Instead of optimizing the quantum programs at th
 e gate level\, we design new quantum programming language primitives and 
 intermediate representations that can maintain the high-level properties 
 of the programs. These high-level properties can then be leveraged to der
 ive new large-scale quantum compiler optimizations beyond the capabilitie
 s of gate-level optimizations. In particular\, we will introduce several 
 optimizations targeting various stages in the workflow of quantum simulat
 ion.\n\nBio: Dr. Gushu Li is an Assistant Professor at the Department of

DESCRIPTION:Abstract: Hamiltonian simulation becomes more challenging as t
 he underlying unitary becomes more oscillatory. In such cases\, an algori
 thm with commutator scaling and a weak dependence\, such as logarithmic\,
  on the derivatives of the Hamiltonian is desired. We introduce a new tim
 e-dependent Hamiltonian simulation algorithm based on the Magnus series e
 xpansion that exhibits both features. Importantly\, when applied to unbou
 nded Hamiltonian simulation in the interaction picture\, we prove that th
 e commutator in the second-order algorithm leads to a surprising fourth-o
 rder superconvergence\, with an error preconstant independent of the numb
 er of spatial grids. The proof of superconvergence is based on semiclassi
 cal analysis that is of independent interest.\n\nBio: Di Fang is an Assis

DESCRIPTION:Abstract: Programmable arrays of single atoms interfaced with 
 optical cavities are a promising platform for quantum computing and quant
 um networking. Optical cavities enable fast and non-destructive readout o
 f individual atomic qubits\; however\, scaling up to many qubits remains 
 a challenge. We recently addressed this by employing locally controlled e
 xcited-state Stark shifts to achieve site-selective hyperfine-state cavit
 y readout across a 10-site array. To further speed up array readout\, we 
 demonstrated adaptive search strategies utilizing global/subset checks. W
 e also demonstrated repeated rounds of classical error correction\, showi
 ng exponential suppression of logical error and extending logical memory 
 fivefold beyond the single-bit idling lifetime. I will present these resu
 lts and describe future directions. As atom arrays approach practical siz
 e limits\, continuing to scale up requires linking arrays in a modular ar
 chitecture. I will present recent work analyzing the prospects of fault-t
 olerantly linking atom arrays using cavity-based interconnects\, describi
 ng both the fidelity and speed requirements for a fault-tolerant modular 
 architecture for neutral atoms. \n---\nJosiah Sinclair is a postdoctoral

DESCRIPTION:In a nonlocal game\, two noncommunicating players cooperate to
  convince a referee that they possess a strategy that does not violate th
 e rules of the game. Quantum strategies allow players to optimally win so
 me games by performing joint measurements on a shared entangled state\, b
 ut finding these strategies can be challenging. In this talk\, we will pr
 ovide an overview of some interesting nonlocal games on graphs and discus
 s a variational algorithm for computing these quantum strategies. When ap
 plied to a specific graph\, our algorithm was able to generate a novel sh
 ort-depth circuit that implements a perfect quantum strategy\, i.e. a str
 ategy that utilizes entanglement as a resource to win the game with proba
 bility one. We will argue how these quantum strategies can act as high-le
 vel benchmarks of quantum devices since these strategies demand non-local
  correlations for their successful execution. Finally\, we will discuss r
 ecent results and challenges when running these quantum strategies on sup
 erconducting and ion-trap quantum devices\, as well as outline some futur
 e research directions for scaling such games.\n\nBio: Dr. Carlos Ortiz Ma

DESCRIPTION:Progress in quantum computing with neutral atom qubits has adv
 anced rapidly with the development of large 2D arrays and high-fidelity e
 ntangling gates. We have used an array of Cs atom qubits to demonstrate a
  variational simulation of the \nLipkin-Meshkov-Glick model incorporating
  noise mitigation techniques. Some new ideas for advancing computational 
 capability based on nonlocal quantum codes and techniques for speeding up
  qubit measurements will be presented\, as well as progress towards photo
 nic remote entanglement.\n---\nMark Saffman is an experimental physicist 
 working in the areas of atomic physics\, quantum and nonlinear optics\, a
 nd quantum information processing. His research team was the first to dem
 onstrate a quantum CNOT gate for the deterministic entanglement of a pair
  of neutral atoms. This was done using dipole mediated interactions betwe
 en highly excited Rydberg atoms. He is currently developing scalable arra
 ys of neutral atoms for quantum computation\, communication\, and sensing
  applications.\n\nHe is the Johannes Rydberg Professor of Physics at the 
 University of Wisconsin-Madison and has been recognized with an Alfred P.
  Sloan fellowship\, a Vilas Associate Award\, the WARF Innovation Award\,
  and is a fellow of the American Physical Society\, and Optica. He has be
 en active in professional service including two decades as an Associate E
 ditor at the Physical Review\, and is the director of The Wisconsin Quant
 um Institute. He also serves as Chief Scientist for Quantum Information a

DESCRIPTION:Quasicrystals are aperiodic with long-range order\, exhibiting
  an absence of translation symmetry and featuring rotational symmetries t
 hat are mathematically forbidden in periodic lattices. In 1984\, Shechtma
 n performed X-ray diffraction measurements on a metallic alloy\, revealin
 g 10-fold rotational symmetry in the diffraction pattern. This work event
 ually led to the redefinition of what constitutes a crystal\, and the rec
 ognition of the reality of aperiodic crystals. Shechtman was then awarded
  the 2011 Nobel prize in chemistry for the discovery of aperiodic crystal
 s. In recent decades\, band structure and its interplay with topology has
  provided deep insight into intriguing behavior in periodic crystalline q
 uantum materials. However\, thirty years after the discovery of aperiodic
  crystals\, the role of the energy spectrum and its interplay with topolo
 gy is not well-understood for quasicrystals because standard theoretical 
 methods used to study the energy spectrum of a crystal rely on translatio
 nal symmetry. Quantum simulation of a quasicrystal would open a window in
 to quasicrystalline "band structure" and topology that is difficult to ac
 cess with theoretical and analytical methods alone. This talk will descri
 be the design of an experiment in which a quantum gas is confined within 
 a 10-fold rotation-symmetric quasiperiodic optical lattice\, and will men
 tion planned first measurements.\n---\nBio: Charles Brown is an Assistant
  Professor of Physics and has expertise in the generation and measurement
  of quantum matter in liquid and gas form. He leads an experimental group
  at Yale that focuses on trapping ultracold atoms in optical lattices to 
 explore how geometry and topology affect emergent properties in exotic qu
 antum materials. He was awarded the AFOSR YIP and NSF CAREER awards for h
 is work exploring the physics of quantum quasicrystals.
