Error-correction typically comes with si gnificant resource overheads\, which motivates the search for implementati ons which can naturally provide error correction in a compact manner. One approach is to use bosonic degrees of freedom to encode information redund antly\, allowing to perform feedback which suppresses errors. I will descr ibe two sets of experiments in which we perform operations and bosonic err or correction using mechanical oscillations of a single trapped ion. In th e first\, we demonstrate the entanglement and subsequent error-correction of logical qubits encoded using superposed displaced squeezed states formi ng periodic structures in phase space. This “GKP” encoding is particul arly well suited to diffusive errors in the oscillator phase space. Then\, using a novel non-linear regime of control\, I will show how we realize n on-linear reservoir engineering to perform confinement of states into fini te-dimensional subspaces which have discrete rotational symmetry\, and whi ch protect from dephasing errors. Alongside coverage of the state-of-the-a rt\, I will provide perspectives as to how these approaches could be embed ded in larger systems.” LOCATION:Office Bldg West / Ground floor / Heinzel Seminar Room (I21.EG.101 )\, ISTA ORGANIZER:Stephanie.Dolot@ist.ac.at SUMMARY:Jonathan Home: Bosonic error-correction codes with trapped ions URL:https://talks-calendar.ista.ac.at/events/6406 END:VEVENT BEGIN:VEVENT DTSTAMP:20260519T192352Z UID:1779195600@ist.ac.at DTSTART:20260519T150000 DTEND:20260519T180000 DESCRIPTION:Speaker: Nati Linial\nhosted by Matthew Kwan and Uli Wagner\nAb stract: Abstract: Let X=[n] be a finite set of points. An (x\,y)-path is a sequence of distinct points that starts with x and ends with y. A path system Π on X is a collection of paths with exactly one (x\,y)- path for every two distinct points x\,y∈X. Think of this path Px\,y a s the chosen path between these two points. We always assume that Py\,x  coincides with Px\,y read in reverse. We say that the path system Π i s consistent if the following holds: For every point z on the path Px\, y\, this path is the concatenation of the paths Px\,z and Pz\,y. It is easy to construct metric consistent path systems: Assign a positive distan ce w(u\,v) with every pair of points u\,v∈X and let Px\,y be a w- shortest (x\,y) path Q\; Is every consistent path system necessarily me tric? The answer is negative and we give various quantitative manifestatio ns of this statement. Skipping the necessary definitions we ask if every c onsistent path system is approximately metric. A: there exist consistent p ath systems with metric distortion Ω(√n). The best result of this form is still unknown. I will briefly survey some of the many results that we already have in this general domain. Every path system gives rise to a gra ph (X\,E) where xy is an edge whenever the path Px\,y=x\,y. Indeed\, many of our results are graph-theoretic. All the papers in this domain are joint with my student Daniel Cizma\, some are also with Maria Chudnovsky\ , if time allows I will also mention a recent result with my students Itai Goldflam.

While weak perturbations of c lassical integrable systems give rise to a mixed phase space of coexisting regular and chaotic trajectories\, analogous behavior in interacting quan tum many-body systems has remained elusive. Here we develop and experiment ally implement a hybrid quantum–classical feedback protocol that autonom ously discovers and stabilizes long-lived regular trajectories in a superc onducting quantum processor. Each iteration combines short-time quantum ev olution with classical optimization that projects the dynamics back onto a low-entanglement variational manifold\, effectively distilling coherence from chaotic evolution. The stabilized trajectories reveal a quantum many- body mixed phase space emerging from nonlinear variational dynamics\, with out a direct analogue in classical or few-body quantum systems.

In this talk\, I will present a first and comprehensive experimental an d theoretical investigation of ULRMs of 174Yb in 6sns 1S0 Rydberg states a cross nearly two decades in principal quantum number and three orders of m agnitude in molecular binding energy. Using the Coulomb Green’s function formalism\, we compute Born–Oppenheimer molecular potentials describing a Rydberg atom perturbed by a ground-state atom and obtain quantitative a greement with high-resolution molecular spectra. This enables the extracti on of low-energy electron-Yb scattering phase shifts\, including the zero- energy s-wave scattering length and the positions of two spin-orbit split p-wave shape resonances. The latter provides strong evidence that the Yb − anion exists only as a metastable resonance. We further demonstrate th e sensitivity of ULRM spectra to the atomic quantum defects\, enabling a p recise determination of the quantum defect of the 6s23f 1F3 state. These f indings establish Yb ULRMs as a powerful probe of low-energy electron–Yb interactions and an ideal platform for exploring Rydberg molecules and lo w-energy scattering physics.

In this talk\, I present a numerical framew ork for modeling closed membranes populated by curved anisotropic componen ts that interact via nematic alignment and couple to active forces. Our si mulations reveal a rich landscape of membrane morphologies arising from th e competition between intrinsic curvature\, nematic interactions\, and act ive stresses. We show how nematic alignment organizes curved inclusions in to defect structures that localize in regions of high curvature\, thereby guiding membrane remodeling and stabilizing complex shapes such as tubules \, necks\, and pearled structures . Active forces further drive the system out of equilibrium\, enabling transitions to morphologies that are inacce ssible in passive systems\, including flattened\, protrusive\, and dynamic ally fluctuating states. These results provide a unified physical picture of how curvature\, orientational order\, and active forces cooperate to co ntrol membrane shape\, with implications for processes ranging from endocy tosis and phagocytosis to cell spreading and motility.

Their excellent coherence properties combined with progr ammable Rydberg interactions have led to intriguing observations such as q uantum phase transitions\, the discovery of quantum many-body scars\, and novel quantum computing architectures. Here\, I am introducing a dual-spe cies Rydberg array that naturally lends itself for measurement-based proto cols [1] such as quantum error correction\, long-range entangled state pre paration\, and measurement-altered many-body dynamics. Furthermore\, Rydbe rg interactions between the two species then lead to novel regimes\, inclu ding greatly enhanced resonant dipole interactions\, that we use to demons trate a two-qubit gate and quantum non-demolition readout [2]. I will pre sent our current experiments on implementing quantum cellular automata in a dual-species array. Cellular automata are famous for producing complex b ehavior as well as universal computation based on simple initial states an d update rules. Here we investigate this paradigm by implementing an updat e rule based on dual species Rydberg blockade and periodic driving. [1] S ingh\, Bradley\, Anand\, Ramesh\, White\, Bernien\, Science 380\, 1265 (20 23).[2] Anand\, Bradley\, White\, Ramesh\, Singh\, Bernien\, Nature Physic s 20\, 1744 (2024).

Whether it is the Facebook network\, whe re 'friendships' emerge or end\, the internet\, where computers connect or disconnect from the network\, or the train network\, where new lines can be created or canceled. This creates specific challenges for algorithms de signed to either run or manage these 'dynamic' networks.A distributed algo rithm is an algorithm that runs on the network. Think of the internet: for computers to communicate through this network\, the algorithm should be i nstalled on both computers\, and both computers won't necessarily have acc ess to the same information. If the network is unstable\, or is simply dyn amic\, the communication between them can drop at any point\, and the algo rithm should be robust to such changes. In this model\, we look at two pro blems: the broadcast problem\, where one computer tries to send a message to every single other computer on the network\, and the majority problem\, where initially each computer is given an opinion among k possible ones\, and the goal is for every computer to know which opinion was originally t he most popular one.A dynamic graph algorithm is an algorithm that manages a dynamic network\, or computes a property on it. Think of the network of webpages. You might want to rank all webpages from the most important one to the least (popular search engines call it the 'PageRank' algorithm). H owever\, every day\, new pages go online\, while old pages go offline. You wouldn't want the algorithm to be run from scratch every night over all o nline webpages\, as this would cost too much energy. Instead\, you would l ike to have an algorithm that\, once it has computed the rank of each webp age at a given time\, be able to handle a few changes\, and update its sol ution accordingly. In the dynamic graph algorithm model\, we look at the m inimum cut problem\, where the goal is is divide the network into two subn etworks\, such that the number of connections from one subnetwork to the o ther is minimized.

Using finite-size quant um-jump simulations\, we show that adding local Rydberg blockade between a toms generates extensive mixed-state entanglement while preserving superra diance. This enables superradiantly accelerated preparation of correlated dark states on a timescale $\\propto (\\log N)/N$\, supported by an early- time analytical solution and numerical simulations. The physical mechanism is Hilbert-space fragmentation of the Dicke ladder into an exponentially branching decay tree\, giving rise to a hierarchy of correlated dark state s.

Whether it is to facilitate metabolite transport\, catalyze reactions\, transmit signals\, or regulate metabolism – proteins are constantly in motion and sample multiple conformational states to fulfill their function. Nuclear magnetic resonance (NMR) spectro scopy is particularly well suited to elucidate the dynamics of biomolecule s on their complex free-energy landscape. In particular\, solid-state magi c-angle spinning (MAS) NMR enables the study of large molecular assemblies \, protein crystals\, or insoluble proteins at atomic resolution without a n inherent molecular size limitation. MAS NMR experiments to probe protein dynamics are extremely versatile and sensitive to motional timescales fro m picoseconds to seconds. Over the past decades\, technological advances\, developments in experimental design\, and new isotope-labeling approaches have further expanded the possibilities of this technique and significant ly improved the accuracy of the determined motional parameters.Functionall y important sites of proteins often contain aromatic residues. Their side- chain motions have therefore long served as valuable indicators of mechani stically relevant dynamics in NMR studies. In this thesis\, site-specifica lly labeled aromatic residues act as sensitive reporters for MAS NMR studi es of protein dynamics. The first part addresses how different environment s impact side-chain motion by probing ring flips of phenylalanines and tyr osines in crystalline proteins and amyloid fibrils. It provides important insights for the analysis of dynamics obtained in non-native protein envir onments and emphasizes the complex factors that determine the timescale of internal dynamics. In the second part\, the focus shifts towards methodol ogical questions regarding the investigation of protein dynamics by 19F MA S NMR. The fluorine nucleus exhibits promising characteristics for NMR stu dies but also presents significant challenges\, which is why the full meth odological potential of 19F MAS NMR has not been fully realized yet. This work demonstrates that paramagnetic doping can considerably reduce the mea surement time and improve the sensitivity of fluorinated samples. Finally\ , 19F MAS NMR is evaluated as a tool for studying protein side-chain dynam ics on the example of tryptophans. The results illustrate the challenges i n analyzing such experiments and lay the foundation for further developmen t of 19F MAS NMR relaxation studies.Taken together\, this thesis highlight s the potential of combining specific isotope labeling\, MAS NMR\, and com plementary methods such as crystallography and computational simulations t o elucidate internal protein dynamics. The further development of such int egrative approaches will be crucial to improving our understanding of comp lex mechanisms and protein function.
