Spin defects in solids possess a far broader set of potential applications, including for biosensing, quantum transduction and memory.

The main examples will be (1) noise in quantum sensing [1] and its suppression in diamond nanoparticles for biosensing [2], (2) crystal field splittings of rare-earth dopants and implications for quantum memory and transduction (i.e. in oxides and GaN) [3], and (3) hybrid quantum systems involving magnets [4]. \r\n[1] PRB 110, 174450 (2024); PRB 110, 024419 (2024).\r\n[2] arXiv:2305.03075\r\n[3] arXiv:2501.03348; arXiv:2501.03353; arXiv:2503.12194\r\n[4] Mater.

In this talk, I will review several prominent examples and their interconnection with fundamental atomic physics and precision measurements. In the first part, I will describe how investigating photoionization of one of the excited states of rubidium led to the development and demonstration of a cold-atom-based ion source with the novel method of monitoring ionic electric fields using highly-excited (Rydberg) atoms. I will also present a new type of Rydberg molecule that is formed as a result of interactions between ions and Rydberg atoms. Next, I will describe precision measurements of the hyperfine structure of a different excited state in rubidium and how these investigations led to a proposal of a novel optical atomic clock that can be an alternative to existing portable technologies. Finally, if time permits, I will discuss a novel technique for atom interferometry based on uninterrupted full spatial confinement and control of atomic wave packets. This approach, termed \u201ctractor atom interferometry\u201d, aims to address drawbacks of the existing setups and provide new applications in fundamental physics and inertial sensing.\r\n\r\nBio: Alisher is originally from Kazakhstan, where he obtained his BS in Physics from Nazarbayev University in Astana.

Systems with more than 1000 qubits in 2D arrays and gate fidelities approaching three nines are being developed by many academic and industrial groups. I will present recent progress at University of Wisconsin-Madison and Infleqtion with physical and logical qubit encodings. Interesting challenges remain in scaling the size and performance to the levels needed for quantum utility. Ultimately a modular approach to quantum computation will enable scaling to millions of qubits, with inter-module connections enabled by photonic links. Recent results on entangling atoms with photons for scaling a modular architecture will be presented. \r\n\r\nBio:\r\nMark Saffman is a physicist working in the areas of atomic physics, quantum and nonlinear optics, and quantum information processing. His research team has been a pioneer in quantum computing with atomic qubits. They were the first to demonstrate a quantum CNOT gate for the deterministic entanglement of a pair of neutral atoms. This was done using interactions between highly excited Rydberg atoms. He is currently developing scalable arrays of neutral atoms for quantum computation, communication, and sensing applications. \r\nHe is the Johannes Rydberg Professor of Physics at the University of Wisconsin-Madison and has been recognized with an Alfred P. Sloan fellowship, a Vilas Associate Award, the WARF Innovation Award, and is a fellow of the American Physical Society, and Optica. He has been active in professional service including two decades as an Associate Editor at the Physical Review, and is the director of The Wisconsin Quantum Institute.

in quantum communication, distributed quantum sensing, and modular quantum computation. In this talk, I will describe two approaches we are pursuing to generate fast and high-fidelity remote entanglement. In the first approach, we have demonstrated a photonic interconnect based on high-fidelity entanglement of the metastable nuclear spin-1\/2 qubit in ytterbium-171 and a telecom-band photon with time-bin encoding. We have realized an atom-photon Bell state fidelity of 0.95 when correcting for atomic measurement errors. As an extension of this work, I will describe a second system based on ytterbium-171 atom arrays in a near-concentric optical cavity. We anticipate the ability to generate atom-atom Bell pairs with fidelity approaching 0.99 and rate of 10^4 ebits\/sec using this telecom photonic interface. In the second approach, I will introduce a novel technique for transporting large tweezer arrays over 200 mm within a single vacuum chamber via a microscope objective mounted on an air-bearing linear motion stage. I will describe our vision for modular quantum computation based on an array of atom arrays.\r\n\r\nBio: Prof. Covey\u2019s research utilizes arrays of individually controlled neutral alkaline-earth atoms in optical tweezers to engineer many-body entangled states. Applications of interest include distributed quantum computing, quantum communication, and quantum-enhanced metrology with atomic array optical clocks.
