DESCRIPTION:Quantum sensing\, known for its high sensitivity and precision
 \, is a rapidly advancing field that enables both ground-breaking scienti
 fic discoveries and practical innovations. In this talk\, I will present 
 experimental evidence of dipole-phonon interactions between a single calc
 ium monoxide ion and its trapping potential\, using single atomic ion as 
 a quantum sensor for measurement. Dipole-phonon interaction offers novel 
 approaches for state preparation\, measurement\, and quantum information 
 control in molecular ion qubits\, offering a promising solution to the sc
 alability challenges of atomic ion systems. I will detail our experimenta
 l setup and methodology\, along with the observed dipole-phonon interacti
 on signals. Additionally\, I will discuss the limitations of observation 
 rates due to the low thermal population in the molecular ground rotationa
 l state at room temperature and potential applications of our findings. \

DESCRIPTION:Quantum networks unlock a broad range of applications in quant
 um information science\, ranging from secure communication to distributed
  sensing and computation. My talk will explore an experimental platform b
 ased on rare-earth ion qubits: emitters inherently shielded from environm
 ental perturbations\, creating near-pristine atomic systems in the solid-
 state. I will present three key advancements:\n\n1. A novel solid-state p
 latform where 171Yb3+ ions in YVO4 are coupled to nanophotonic cavities a
 nd utilized as highly coherent optically addressed qubits.\n2. Determinis
 tic memory registers based on nuclear spin ensembles\, capable of storing
  and retrieving quantum states on demand\n3. Multiplexed entanglement lin
 ks which utilize multiple rare-earth ions to eliminate quantum communicat
 ion rate bottlenecks between remote nodes.\n\nI will conclude with a visi
 on on scaling these rare-earth ion systems for a range of quantum communi
 cation applications such as quantum repeaters and cluster-state generatio
 n.\nTime-permitting\, I will also discuss ongoing postdoctoral research o
 n quantum networking with 87Rb atom arrays. The goal is to use high-fines
 se Fabry-Perot cavities to interface with telecommunication-band optical 
 transitions\, enabling seamless integration with silicon photonics and en
 tanglement over metropolitan distances.\n---\nAndrei Ruskuc is a postdoct
 oral fellow in the Lukin group at Harvard\, researching atomic platforms 
 for quantum networking. He completed his PhD in 2023 at Caltech under And
 rei Faraon\, focusing on rare-earth ion-based quantum networking technolo
 gies. He holds bachelor's and master's degrees from the University of Cam
 bridge (2017). His expertise spans quantum networking with both solid-sta
 te and neutral atom platforms.\n---\nSpring 2025 Upcoming Speakers\n\n20

DESCRIPTION:Abstract: We address a longstanding question in quantum comput
 ing: Can quantum computers provide exponential speedups for optimization 
 problems? We introduce Decoded Quantum Interferometry (DQI)\, which reduc
 es optimization problems to decoding problems by exploiting structure in 
 the Fourier spectra of the objective functions. DQI achieves an exponenti
 al speedup for a previously-studied optimization problem that generalizes
  polynomial regression and has been studied in the contexts of cryptanaly
 sis and classical error correction. DQI is a radical departure from prior
  approaches\, as it relies on neither the Abelian hidden subgroup problem
  nor a Hamiltonian formulation.\n\nSpring 2025 Upcoming Speakers\n\n6 Mar

DESCRIPTION:Abstract: In this talk I will present two new applications of 
 trapped ion quantum computers to quantum simulation. In the first\, we ex
 perimentally simulate the transfer of an electronic excitation along a ch
 ain of macromolecules\, capable of interacting by exchanging both electro
 ns and phonons. This two-stage experiment is unique in that the initial s
 tate preparation relies not on a prior construction of the wavefunction f
 rom its nanoscopic constituents\, but rather from a model fit to molecula
 r spectroscopy data using a hybrid quantum-classical algorithm. In the se
 cond experiment\, we demonstrate an efficient method for thermal state pr
 eparation on quantum computers uniquely adapted to trapped-ion hardware. 
 Taking as our example a simulation of the quantum chromodynamic (QCD) pha
 se diagram\, we show how quantized motional modes can replace a register 
 of spin ancillae to provide the required dissipation for controlled therm
 al state creation. In this case\, the alternative use of motional ancilla
 e effectively doubles the simulation space supported by the quantum compu
 ter.\n\n---\nSpring 2025 Upcoming Speakers\n\n23 Jan: Lu Qi\n6 Feb: Andre

DESCRIPTION:Abstract: Trapped atomic ions are one of the leading qubit can
 didates for quantum computing. The fidelity of quantum gates and the nois
 e performance of a quantum processor built on this platform depends on th
 e degree of isolation between the classical environment and the ions. One
  leading noise source is electric field noise. Additive manufacturing has
  introduced the possibility of generating accurate\, replicable and scala
 ble ion traps with geometries that promise to reduce sensitivity to this 
 noise source. In this talk\, I will describe miniaturized RF Paul traps t
 hat we have fabricated at LLNL using high-resolution 3D printing approach
  based on two-photon polymerization and share the results of initial test
 s.\nThis work was performed under the auspices of the U.S. Department of 
 Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-0
 7NA27344.\n---\n\nBIO: Dr. Kristin (Kristi) Beck is a staff scientist in 
 the LLNL Quantum Coherent Device Physics Group and the director of the Li

 um computing stack\, from device hardware and gate design to testbed arch
 itecture. Her current research portfolio includes testing novel control h
 ardware and working with optimal control generation for superconducting t
 ransmons\; and designing\, modeling and testing 3D printed traps for trap
 ped ions.\n\nKristi joined LLNL in 2020. Prior to LLNL\, Kristi was a sen
 ior physicist at the startup quantum computing company IonQ. She complete
 d a postdoctoral fellowship in the Joint Quantum Institute at the Univers
 ity of Maryland in 2018. She received her Ph.D. from MIT in 2016\, her M.

DESCRIPTION:Abstract: In 1948\, Shannon developed information theory and p
 roved that classical communication channels had a well-defined capacity t
 hat limited the rate at which you could send information over them. It tu
 rns out that quantum communication channels do not have one capacity\, bu
 t several capacities. We explain several of the major capacities of quant
 um channels\, give formulas for them\, and explain how they arise.\n---\n

DESCRIPTION:The QAOA is a quantum algorithm designed to find good solution
 s to combinatorial optimization problems. It consists of an alternation o
 f simple-to-implement unitary transformations. Worst case performance gua
 rantees have been proven for MaxCut and other problems.  For the Sherring
 ton Kirkpatrick model\, which has random all-to-all connections\, QAOA pe
 rformance has been established (up to depth 20) on typical instances in t
 he infinite size limit.  The QAOA has quantum supremacy at its shallowest
  depth both in worst case and for typical instances coming from the SK mo
 del.   Recently it has been shown that for MaxCut on 3-regular graphs\, i
 nstance-independent parameters can be chosen in advance that work well on
  all instances at high sizes. This eliminates the necessity of searching 
 for good parameters when running the algorithm.  Furthermore  QAOA perfor
 mance guarantees can be turned into statements about the size of cuts in 
 large girth 3-regular graphs and the QAOA is exponentially faster than th
 e best known classical algorithms for finding these large cuts.\n\n---\nE
 dward Farhi is a physicist working on quantum computation as a Principal 
 Scientist at Google. In 2018 he retired from his position as Professor of
  Physics at the Massachusetts Institute of Technology where he served as 
 the Director of Theoretical Physics for twelve years.  Farhi was trained 
 as a theoretical particle physicist with interests in astrophysics and ge
 neral relativity where he made several notable contributions.  Since the 
 late 90's\, he has been studying how to use quantum mechanics to gain alg
 orithmic speedup in solving problems that are difficult for conventional 
 computers. He along with collaborators introduced the idea of continuous 
 time Hamiltonian based quantum computing which led to quantum walk algori
 thms and the quantum adiabatic algorithm.  Farhi\, Goldstone and Gutmann 
 introduced the QAOA in 2014 and it has been the focus of many papers look
 ing at shallow depth quantum algorithms for optimization.\n\n---\nSpring
