While it has bee n thoroughly studied for simple quantum systems such as two-level systems or harmonic oscillators\, it has recently become available for complex\, c orrelated quantum many-body systems. In the last years\, we have developed systems combining cavity QED with cold Fermi gases. In such a system\, v irtual photon exchanges between atoms yield a long-range interaction leadi ng to emergent phenomena. I will describe how it induces charge-density wa ve ordering\, and the deep insights on this transition provided by real-ti me measurements and high spatial resolution. I will then discuss the inter play of pairing\, Pauli blocking and light-matter interactions in this sys tem\, the status of our understanding and some open questions. Last\, I wi ll outline the perspective open for quantum simulations in this platform\, both from the conceptual and technological point of view.  LOCATION:Office Building West/Ground Floor/Heinzel Seminar Room\, ISTA ORGANIZER: SUMMARY:Jean-Philippe Brantut: Quantum Simulations with Atoms and Photons URL:https://talks-calendar.ista.ac.at/events/6210 END:VEVENT BEGIN:VEVENT DTSTAMP:20260416T010035Z UID:1779181200@ist.ac.at DTSTART:20260519T110000 DTEND:20260519T120000 DESCRIPTION:Speaker: Jonathan Home\nhosted by Julian Léonard\nAbstract: A bstract: The development of useful quantum computers will rely on the abil ity to suppress errors which occur both naturally and through the erroneou s application of gate operations. 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:20260416T010035Z UID:1780390800@ist.ac.at DTSTART:20260602T110000 DTEND:20260602T120000 DESCRIPTION:Speaker: Hannes Bernien\nhosted by Maksym Serbyn\nAbstract: Rec onfigurable arrays of neutral atoms have emerged as a leading platform for quantum science. 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).
