DESCRIPTION:Abstract: Hybrid quantum systems provide a promising route tow
 ard scalable quantum technologies by combining the strengths of different
  physical platforms. Neutral atoms offer long coherence times and reprogr
 ammability\, superconducting circuits enable fast programmable interactio
 ns\, and photonic modes provide long-distance connectivity. In this talk\
 , I will discuss our past work on developing quantum interconnects across
  these platforms-linking Rydberg atoms\, superconducting microwave caviti
 es\, and photonic channels-and outline ongoing efforts in my group toward
  building modular hybrid architectures for quantum state transfer\, entan
 glement generation\, and networked quantum processors.\n\nBio: Aziza Sule
 ymanzade is an Assistant Professor of Physics at UC Berkeley. Her group e
 xplores hybrid quantum systems that combine Rydberg atoms\, superconducti
 ng circuits\, and nanophotonics. Her research focuses on creating novel q
 uantum interfaces and generating entanglement resources that link these p
 latforms for quantum information processing\, communication\, and sensing
 . Prior to joining Berkeley\, Aziza was a postdoctoral scholar at Harvard
  University\, working on silicon-vacancy-based quantum networks in diamon
 d nanophotonic cavities. She earned her Ph.D. in Physics from the Univers
 ity of Chicago\, where her dissertation on Rydberg cavity-QED in optical 
 and superconducting cavities earned the 2023 Deborah Jin Award for Outsta
 nding Doctoral Thesis. She received an undergraduate degree in Physics fr
 om Harvard University.\n---\nUpcoming seminars:\n\n18 Sep: Sitan Chen\n02

DESCRIPTION:Abstract: As the computational resources for existing quantum 
 devices continue to grow\, so too does their potential to help us analyze
  quantum experimental data and learn about the physical universe. In this
  talk\, I will describe recent progress towards understanding the fundame
 ntal capabilities and limitations of near- and intermediate-term devices 
 for such tasks. In the first part of the talk\, I will provide a gentle s
 urvey on our work in this direction over the last few years\, focusing on
  the tradeoff between statistical complexity and quantum memory for funda
 mental tasks like full tomography\, state certification\, shadow tomograp
 hy\, Pauli channel estimation\, and purity estimation. In the second part
  of the talk\, I will describe a new general framework for proving tradeo
 ffs between the amount of data one has available and the computational co
 mplexity needed for quantum learning\, inspired by tools from the literat
 ure on information-computation gaps for classical statistical inference.\
 n\nShort bio: Sitan Chen is an Assistant Professor of Computer Science at
  Harvard University\, where he is a member of the Theory of Computation\,
  the ML Foundations group\, and the Harvard Quantum Initiative. Previousl
 y\, he was an NSF math postdoc at UC Berkeley\, after completing his PhD 
 in EECS at MIT in 2021. He is broadly interested in algorithmic questions
  about learning from data\, most recently related to the science and theo
 ry of localization-based generative modeling\, and the design of quantum 
 protocols for learning about the physical universe. His work has been rec
 ognized with an NSF CAREER award\, an ICML Outstanding Paper Award\, and 
 the Harvard Dean's Competitive Fund for Promising Scholarship.\n---\n\nUp

DESCRIPTION:Ion-molecule reactions are fundamental to the chemistry that d
 rives processes in the interstellar medium\, but experimental measurement
 s of these reactions are scarce due to significant technical challenges. 
 We apply techniques from the cold atom field to examine ion-molecule reac
 tions under well-controlled conditions that replicate the environment of 
 space.\n\nBenzene\, a key precursor to larger polycyclic aromatic hydroca
 rbons (PAHs)\, has long been proposed to form in space through a sequence
  initiated by acetylene protonation. We present the first experimental st
 udy of this pathway under single-collision conditions and find that\, con
 trary to predictions\, it terminates at the formation of C₆H₅⁺-a species 
 unreactive to both acetylene and hydrogen\, which disproves a widely cite
 d mechanism for interstellar benzene formation.\n\nBuilding on this appro
 ach\, we extend our investigation to related ion-molecule systems and fin
 d a consistent trend: reactions of small carbocations and neutral molecul
 es proceed through successive additions until an aromatic molecule is for
 med\, at which point the ion is unreactive. This behavior suggests that a
 romatic stabilization acts as a natural endpoint for many interstellar io
 n-molecule growth processes\, which has important implications for unders
 tanding the origins and abundance of PAHs in space.\n---\nHeather Lewando

 tum Initiative focused on Education and Workforce. She leads two research
  programs\, one in experimental molecular physics\, and the other in phys
 ics education research. Her molecular physics research efforts focus on s
 tudying interactions and reactions of cold\, chemically important molecul
 es and ions. Her physics education research program studies ways to incre
 ase students' proficiency in experimental scientific practices\, as well 
 as research in the area of quantum science education and workforce develo

DESCRIPTION:Abstract: Entanglement is a distinctive feature of quantum mec
 hanics\, yet precisely characterizing its advantages in quantum informati
 on processing can be challenging. In this talk\, we demonstrate that quan
 tum entanglement can provide exponential speedup in learning physical pro
 cesses\, on both discrete-variable and continuous-variable quantum system
 s. We show such advantages persist even under realistic imperfections\, a
 nd experimentally demonstrate the advantages on two different platforms. 
 Concretely\, the first result is about learning n-qubit Pauli channels\, 
 with applications in scalable noise characterization of superconducting q
 ubits\; The second result is about learning n-mode bosonic random displac
 ement channels\, with demonstrations on a quantum photonic platform. Our 
 work highlights a new paradigm of practical quantum advantages and provid
 es new insights on the usefulness of quantum entanglement as a resource.\

DESCRIPTION:Abstract: Hybrid quantum systems provide a promising route tow
 ard scalable quantum technologies by combining the strengths of different
  physical platforms. Neutral atoms offer long coherence times and reprogr
 ammability\, superconducting circuits enable fast programmable interactio
 ns\, and photonic modes provide long-distance connectivity. In this talk\
 , I will discuss our past work on developing quantum interconnects across
  these platforms-linking Rydberg atoms\, superconducting microwave caviti
 es\, and photonic channels-and outline ongoing efforts in my group toward
  building modular hybrid architectures for quantum state transfer\, entan
 glement generation\, and networked quantum processors.\n\nBio: Aziza Sule
 ymanzade is an Assistant Professor of Physics at UC Berkeley. Her group e
 xplores hybrid quantum systems that combine Rydberg atoms\, superconducti
 ng circuits\, and nanophotonics. Her research focuses on creating novel q
 uantum interfaces and generating entanglement resources that link these p
 latforms for quantum information processing\, communication\, and sensing
 . Prior to joining Berkeley\, Aziza was a postdoctoral scholar at Harvard
  University\, working on silicon-vacancy-based quantum networks in diamon
 d nanophotonic cavities. She earned her Ph.D. in Physics from the Univers
 ity of Chicago\, where her dissertation on Rydberg cavity-QED in optical 
 and superconducting cavities earned the 2023 Deborah Jin Award for Outsta
 nding Doctoral Thesis. She received an undergraduate degree in Physics fr
 om Harvard University.\n---\nUpcoming seminars:\n\n20 Nov: Jeff Thompson\

DESCRIPTION:ALTERNATE LOCATION: SUITE 550 CHESTERFIELD\n---\nAbstract: Spo
 ntaneously emitted photons are entangled with the internal degrees of fre
 edom of their emitting atoms\; interfering and measuring these photons ca
 n therefore entangle spatially separated atoms as a resource for quantum 
 information processing. Confinement in a single mode facilitates the phot
 on interference needed to generate entanglement. Current demonstrations r
 ely on bulk photon-collection and manipulation optics that suffer from mo
 de-matching challenges and system-to-system variability-factors that impe
 de scaling to the large numbers of entangled pairs needed for quantum inf
 ormation processing.  To address these limitations\, we demonstrate a col
 lection method that enables passive phase stability\, straightforward pho
 tonic manipulation\, and intrinsic reproducibility. Specifically\, we eng
 ineer a waveguide-integrated grating to couple photons emitted from a tra
 pped ion into a single optical mode within a microfabricated ion-trap chi
 p. We are now working toward collecting and interfering photons from sepa
 rate ions in different zones of the chip to generate photon-mediated enta
 nglement. This proof-of-principle demonstration could lay the foundation 
 for leveraging the inherent stability and reproducibility of integrated p
 hotonics to create\, manipulate\, and measure multipartite quantum states
  in arrays of quantum emitters.\n\nBio: I am a PhD student at MIT working
  with Prof. Isaac Chuang and Dr. John Chiaverini on integrated photonics 
 for trapped ions. My first exposure to ion trapping was measuring isotope
  shifts in calcium ions with Prof. Charlie Doret during my bachelor's stu
 dies at Williams College. Before starting a PhD\, I worked in the quantum
 -information side of the NIST Ion Storage Group for a year. Since startin
 g graduate school\, I have built a cryogenic ion trapping apparatus for i
 ntegrated photonic traps and studied ion dynamics in a phase-stable polar
 ization gradient\, as well as integrated photon collection. Some of my fa
 vorite ion-related topics are photonics for structured light\, quantum ne
 tworks\, and quantum computing architectures.
