2A.00003: Evidence of twosource King nonlinearity in spectroscopic fifthforce search in Yb+ Diana P. L. Aude Craik Isotopeshift spectroscopy has recently been put forward as a tabletop method for searching for a hypothetical boson that mediates an interaction between the neutron and the electron. The Yukawa potential generated by this boson would lead to neutronnumberdependent shifts in atomic transition frequencies. When measured on at least two transitions, these shifts can be displayed in a “King plot”, which will exhibit nonlinearities in the presence of effects beyond the expected firstorder standard model shifts.

2A.00004: JILA's search for the electron's electric dipole moment: a unique approach to searches for new physics Tanya Roussy We are probing TeVscale physics with a unique tabletop experiment which combines trapped molecular ions, rotating bias fields, orientationresolved detection, and over a dozen lasers to both measure the electron's electric dipole moment and constrain potential dark matter candidates. In this talk I will introduce the essence of our measurement as well as our methods for constraining both dark matter and parityviolating physics.

2A.00006: Quantum metrology enhanced by quantum error correction Sisi Zhou Rapid experimental progress has brought quantum metrology, the science of measurements and estimation in quantum systems, to the forefront of quantum science in the past decades. In this talk, I focus on the challenge of noise in quantum metrology from a quantum information perspective, and address the question of determining the ultimate estimation limits in quantum metrology under noise. In particular, we identify a simple criterion on general quantum systems that determines whether the Heisenberg limit in quantum metrology is achievable or not. We then explore quantum error correction as a powerful tool to achieve the ultimate estimation precision in both cases. Finally we present examples of quantum errorcorrecting codes for sensing in practical physical systems.

2A.00007: Optimal metrology with programmable quantum sensors Christian Marciniak Quantum sensors are an established technology that has created new opportunities for precision sensing across the breadth of science. Using entanglement for quantumenhancement will allow us to construct the next generation of sensors that can approach the fundamental limits of precision allowed by quantum physics. However, determining how stateoftheart sensing platforms may be used to converge to these ultimate limits is an outstanding challenge. In this talk I will present our progress in this regard, where we merge concepts from the field of quantum information processing with metrology, and successfully implement experimentally a programmable quantum sensor operating close to the fundamental limits imposed by the laws of quantum mechanics. We achieve this by using lowdepth, parametrized quantum circuits implementing optimal input states and measurement operators for a sensing task on a trapped ion experiment, particularly generalized Ramsey interferometery. We further perform ondevice quantumclassical feedback optimization to `selfcalibrate' the programmable quantum sensor. This ability illustrates that this next generation of quantum sensor can be employed without prior knowledge of the device or its noise environment.

2A.00008: Quantum optomechanics and dark matter across disparate scales Daniel Carney The only things we know definitively about dark matter are roughly how much there is and that it gravitates. In particular, dark matter could have a wide range of possible masses and couplings. Quantumlimited mechanical sensors provide a robust platform to look for dark matter in many different regimes, and I will review the program of experiments emerging around this idea. After reviewing some current searches for certain light and mediummass dark matter candidates, I will focus on the efforts of the Windchime collaboration, which aims to build an array of millions of optomechanical devices sensitive enough to search for heavy dark matter purely through its gravitational coupling.

2A.00010: Control and detection of molecules in optical tweezers Lewis R Picard Advances in quantum manipulation of molecules bring unique opportunities, including the use of molecules to search for new physics, harnessing molecular resources for quantum engineering, and exploring chemical reactions in the ultralow temperature regime. Thus far, the coldest samples of neutral molecules have been prepared via association of ultracold atoms, with full quantum state control demonstrated in this system. The detection of these molecules is destructive, however, and relies on coherent transfer of molecules back to atoms. Inspired by work on detection of molecular ions via cotrapped atomic ions, I will discuss several approaches that we are pursuing utilizing messenger atoms (including atoms in Rydberg states) to realize the statesensitive detection of neutral molecules. I will also discuss extending full state control to a reconfigurable 1D tweezer array of 5 or more molecules.

2A.00011: The HUNTER experiment: Searching for Sterile Neutrinos in laser trapped ^131Cs Paul Hamilton The HUNTER experiment (Heavy Unseen Neutrinos from Total Energymomentum Reconstruction) is a search for sterile neutrinos with masses in the keV range. Radioactive decays of lasercooled 131Cs will be reconstructed using reactionmicroscope spectrometers to detect all charged decay products with high solid angle efficiency. This reconstruction determines the mass of the undetected neutrino with keVscale resolution and places limits on the coupling of a keVscale sterile neutrino to SM neutrinos.

2A.00012: Bounds on the bizarrity of the Universe from experiments with trapped, cold, charged particles Hartmut Haeffner In order to understand nature better, humans often had to expand their horizon with seemingly bizarre concepts. In the probably most targeted search for such new underlying concepts, theorists explore hypothetical concepts and make predictions which can be tested in controlled experiments. I will focus on two instances where highprecision control of trapped ions and electrons allows us to place bounds on such concepts.

2A.00014: Simulating QCD with quantum tools? Zohreh Davoudi The strong force in nature, described by the quantum and relativistic framework of quantum chromodynamics (QCD), has long generated an active and growing field of research and discovery. In fact, despite its development over five decades ago, it still leaves us with many exciting questions to explore in the 21st century, with a multibilliondollar experimental investment that aims to understand the core of matter, and how matter interacts with candidates of new physics models, such as dark matter. While an extremely successful theoretical and computational program called lattice QCD has enabled a firstprinciples look into some properties of matter, we have yet to come up with a computationally more capable tool to predict the complex and surprising dynamics of matter from the underlying interactions. Can a large reliable (digital or analog) quantum simulator eventually enable us to study the strong force? What does a quantum simulator have to offer to simulate QCD and how far away are we from such a dream? In this talk, I will describe a vision for how we may go on a journey toward quantum simulating QCD, by motivating the need for novel theoretical, algorithmic, and hardware approaches to quantumsimulating this unique problem, and by providing examples of the early steps taken to date in establishing a quantumcomputational latticeQCD program.

2A.00015: Searching for dark matter and new physics with nuclear spins William Terrano I will describe the results of two new dark matter searches with comagnetometers, and possible avenues for improvement. Comagnetometry is—in absolute energy units—the most sensitive way of measuring the splitting between quantum states, measuring the nuclear spinup/spindown splitting at the 1e26 level. Based purely on existing technology, there is room for several orders of magnitude in further improvement in statistical sensitivity. New physics scenarios that comagnetometers can probe include EDMs, violations of Lorentz invariance, Goldstone bosons from new highenergy symmetries, spindependent and CPviolating longrange forces, and axionic dark matter.
