DESCRIPTION:PROGRAMMABLE INDIVIDUAL OPTICAL ADDRESSING FOR TRAPPED-ION QUAN
 TUM\nINFORMATION PROCESSORS \n\nTrapped ions are among the most advanced p
 latforms for quantum\ncomputation and simulation. Programmable\, arbitrary
 \, and precise\ncontrol—usually through laser-induced light-matter inter
 action—is\nrequired to tune ion-ion interactions. These interactions tra
 nslate\ninto diverse parameters of the system under study. Current\ntechno
 logies grapple with scalability issues in large ion chains and\nwith \"cro
 sstalk\" due to micron-level inter-ion separation. \n\nIn this talk\, we p
 resent our development of two optical addressing\nsystems optimized for no
 n-coherent and coherent quantum controls\,\nrespectively. \n\nThe first ad
 dressing system employs a reprogrammable hologram to\nmodulate the wavefro
 nt of the addressing beam\, thereby engineering the\namplitude and phase p
 rofile of light across the ion chain. Our\nimplementation compensates for 
 optical aberrations in the system down\nto λ/20 RMS and exhibits less tha
 n 10−4 intensity cross-talk error.\nThis results in more than 99.9% fide
 lity when resetting the state or\n99.66% when reading out the state of an 
 individual ion without\ninfluencing adjacent ions. This scheme can be read
 ily extended to over\na hundred ions and adapted to other platforms\, such
  as neutral atom\narrays. \n\nAdditionally\, we introduce another addressi
 ng design\, tailored for\ncoherent quantum operations through Raman transi
 tions. This design\nuses a mirrored acoustic-optical deflector (AOD) setup
  to optimize\noptical power scaling and sidestep the undesired site-depend
 ent\nfrequency shift commonly observed in AOD-based setups. \n\nADD EVENT

DESCRIPTION:CRITICAL PHASE AND SPIN SHARPENING IN SU(2)-SYMMETRIC MONITORED
 \nQUANTUM CIRCUITS\n\nMonitored quantum circuits exhibit entanglement tran
 sitions at certain\nmeasurement rates. Such a transition separates phases 
 characterized by\nhow much information an observer can learn from the meas
 urement\noutcomes. We study SU(2)-symmetric monitored quantum circuits\, u
 sing\nexact numerics and a mapping onto an effective statistical-mechanics
 \nmodel. Due to the symmetry's non-Abelian nature\, measuring qubit pairs\
 nallows for nontrivial entanglement scaling even in the\nmeasurement-only 
 limit. We find a transition between a volume-law\nentangled phase and a cr
 itical phase whose diffusive purification\ndynamics emerge from the non-Ab
 elian symmetry. Additionally\, we\nidentify a “spin-sharpening transitio
 n.” Across the transition\,\nthe rate at which measurements reveal infor
 mation about the total spin\nquantum number changes parametrically with sy
 stem size.\n\nReference\nhttps://journals.aps.org/prb/abstract/10.1103/Phy

DESCRIPTION:POSITIVITY AND SUM-OF-SQUARES IN QUANTUM INFORMATION\n\nA multi
 variate polynomial is said to be positive if it takes only\nnon-negative v
 alues over reals. Hilbert's 17th problem concerns\nwhether every positive 
 polynomial can be expressed as a sum of squares\nof other polynomials. In 
 general\, we say a noncommutative polynomial\nis positive (resp. matrix po
 sitive) if plugging operators (resp.\nmatrices) always yields a positive o
 perator. Many problems in math and\ncomputer science are closely connected
  to deciding whether a given\npolynomial is positive and finding certifica
 tes (e.g.\, sum-of-squares)\nof positivity.\n\nIn the study of nonlocal ga
 mes in quantum information\, we are\ninterested in tensor product of free 
 algebras. Such an algebra models\na physical system with two spatially sep
 arated subsystems\, where in\neach subsystem we can make different quantum
  measurements. The recent\nand remarkable MIP*=RE result shows that it is 
 undecidable to\ndetermine whether a polynomial in a tensor product of free
  algebras is\nmatrix positive. In this talk\, I'll present joint work with
  Arthur\nMehta and William Slofstra\, in which we show that it is undecida
 ble to\ndetermine positivity in tensor product of free algebras. As a\ncon
 sequence\, there is no sum-of-square certificate for positivity in\nsuch a
 lgebras.\n\nADD EVENT TO CALENDAR\n\nApple [https://www.addevent.com/event

DESCRIPTION:TIME-RESOLVED QUANTUM KEY DISTRIBUTION USING SEMICONDUCTOR QUAN
 TUM\nDOTS WITH OSCILLATING PHOTONIC STATES\n\nAbstract: Quantum dot-based
  entangled photon sources are promising\ncandidates for quantum key distri
 bution (QKD)\, as they can in\nprinciple emit deterministically\, with hig
 h brightness and low\nmultiphoton contribution. However\, quantum dots (QD
 ) often inherently\npossess a fine structure splitting (FSS). Since the en
 tangled photonic\nstate in the presence of non-zero FSS is oscillating\, o
 ne must settle\nfor a lower efficiency source through temporal post-select
 ion or a\nlower measured entanglement fidelity. In both cases\, the overal
 l key\nrate is reduced. Our QKD analysis shows that this trade-off can be\
 novercome by constructing a time-resolved QKD protocol where all photon\np
 airs emitted by a QD with non-zero FSS can be used in secret key\ngenerati
 on. This protocol works only when the detection system's\ntemporal resolut
 ion is much smaller than the FSS period. By\nimplementing our protocol\, h
 igher key rates can be achieved as\ncompared to previous QKD experiments w
 ith QD entangled photon pair\nsources.\n\nADD EVENT TO CALENDAR\n\nApple [

DESCRIPTION:SOME LEARNING BOUNDS AND GUARANTEES FOR TESTING (QUANTUM) HYPOT
 HESES\n\nMachine learning is a powerful tool\, yet we often do not know ho
 w well\na learning algorithm might perform on any given task. One standard
 \napproach to bound the accuracy of a learning algorithm is to reduce\nthe
  learning task to hypothesis testing. Fano's inequality then states\nthat 
 a large amount of mutual information between the learner's\nobservations a
 nd the set of unknown parameters is a necessary\ncondition for success. \n
 \nIn this talk\, I will describe how such a condition is also sufficient\n
 for succeeding at some learning task\, thereby providing a purely\ninforma
 tion-theoretic guarantee for learning. Noting that this\nguarantee has an 
 immediate extension to quantum information theory\, I\nwill then introduce
  the task of \"testing quantum hypotheses\"\, in which\nthe unknown parame
 ters of the learning task are prepared in a quantum\nregister in superposi
 tion (rather than being sampled stochastically)\nand the learner's success
  at this task is measured by their ability to\nestablish quantum correlati
 ons with that register. I will discuss\nongoing attempts to characterize t
 his scenario.\n\nADD EVENT TO CALENDAR\n\nApple [https://www.addevent.com/

DESCRIPTION:ANALOG QUANTUM SIMULATIONS USING A PARAMETRIC MULTIMODE CAVITY\
 n\nWhile universal quantum computers are still years away from being used\
 nfor simulating complicated quantum systems\, analog quantum simulators\nh
 ave become an increasingly attractive approach to studying\nclassically in
 tractable quantum systems in condensed matter physics\,\nchemistry\, and h
 igh-energy physics.  \n\nWe propose a programmable platform based on a s
 uperconducting\nmultimode cavity. The unique design of the cavity allows u
 s to program\narbitrarily connected lattices where the coupling strength a
 nd phase\nof each individual coupling are highly programmable via parametr
 ically\nactivated interactions. The effectiveness of the cavity-based AQS\
 nplatform was demonstrated by the experimental simulation of two\ninterest
 ing models. First\, we simulated the effect of a fictitious\nmagnetic fiel
 d on a 4-site plaquette of a bosonic Creutz ladder. We\nobserved topologic
 al features such as emergent edge states and\nlocalized soliton states. Th
 e platform's ability is further explored\nby introducing pairing (downconv
 ersion) terms to observe features of\nthe Bosonic Kitaev chain (BKC)\, suc
 h as chiral transport and\nsensitivity to boundary conditions.
