MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to explore fundamental physics with atom interferometry over 100-meter baseline. This novel detector will search for ultralight dark matter, test mechanics in new regimes, and serve as technology pathfinder future gravitational wave detectors previously unexplored frequency band. It combines techniques demonstrated state-of-the-art 10-meter-scale interferometers the latest technological advances of world's...
Assembling and maintaining large arrays of individually addressable atoms is a key requirement for continued scaling neutral-atom-based quantum computers simulators. In this work, we demonstrate new paradigm assembly atomic arrays, based on synergistic combination optical tweezers cavity-enhanced lattices, the incremental filling target array from repetitively filled reservoir. protocol, provide microscopic rearrangement atoms, while lattices enable creation numbers traps with sufficient...
Axion-like particles are promising candidates to make up the dark matter of universe, but it is challenging design experiments that can detect them over their entire allowed mass range. Dark in general, and particular axion-like hidden photons, be as light roughly $10^{-22} \;\rm{eV}$ ($\sim 10^{-8} \;\rm{Hz}$), with astrophysical anomalies providing motivation for lightest masses ("fuzzy matter"). We propose experimental techniques direct detection range from $10^{-13} 10^2 \;\rm{Hz}$) down...
We report the first realization of large momentum transfer (LMT) clock atom interferometry. Using single-photon interactions on strontium ^{1}S_{0}-^{3}P_{1} transition, we demonstrate Mach-Zehnder interferometers with state-of-the-art separation up to 141 ℏk and gradiometers 81 ℏk. Moreover, circumvent excited state decay limitations extend gradiometer duration 50 times lifetime. Because broad velocity acceptance interferometry pulses, all experiments are performed laser-cooled atoms at a...
Measurement-based quantum error correction relies on the ability to determine state of a subset qubits (ancillas) within processor without revealing or disturbing remaining qubits. Among neutral-atom-based platforms, scalable, high-fidelity approach midcircuit measurement that retains ancilla in suitable for future operations has not yet been demonstrated. In this work, we perform maging using narrow-linewidth transition an array tweezer-confined Yb171 atoms demonstrate nondestructive...
Floquet engineering offers a compelling approach for designing the time evolution of periodically driven systems. We implement periodic atom-light coupling to realize atom optics on strontium ^{1}S_{0}-^{3}P_{1} transition. These reach pulse efficiencies above 99.4% over wide range frequency offsets between light and atomic resonance, even under strong driving where this detuning is order Rabi frequency. Moreover, we use compensate differential Doppler shifts in large momentum transfer...
We introduce a new jet algorithm called XCone, for eXclusive Cone, which is based on minimizing the event shape N -jettiness. Because -jettiness partitions every into regions and beam region, XCone an exclusive that always returns fixed number of jets. use “conical geometric” measure well-separated jets are bounded by circles radius R in rapidity-azimuth plane, while overlapping automatically form nearest-neighbor “clover jets”. This avoids split/merge criteria needed inclusive cone...

Measurement-based quantum error correction relies on the ability to determine state of a subset qubits (ancillae) within processor without revealing or disturbing remaining qubits. Among neutral-atom based platforms, scalable, high-fidelity approach mid-circuit measurement that retains ancilla in suitable for future operations has not yet been demonstrated.

We show how the recently proposed XCone jet algorithm [1] smoothly interpolates between resolved and boosted kinematics. When using standard algorithms to reconstruct decays of hadronic resonances like top quarks Higgs bosons, one typically needs separate analysis strategies handle regime well-separated jets fat with substructure. XCone, by contrast, is an exclusive cone that always returns a fixed number jets, so regions remain even when (sub)jets are overlapping in regime. In this paper,...
Arrays of optically trapped neutral atoms are a promising architecture for the realization quantum computers. In order to run increasingly complex algorithms, it is advantageous demonstrate high-fidelity and flexible gates between long-lived highly coherent qubit states. this work, we universal gate-set with individually controlled parallel application single-qubit two-qubit operating on ground-state nuclear spin in arrays tweezer-trapped $^{171}$Yb atoms. We utilize long lifetime, control,...
Transitioning from quantum computation on physical qubits to encoded, logical can improve the error rate of operations, and will be essential for realizing valuable computational advantages. Using a neutral atom processor with 256 qubits, each an individual Ytterbium atom, we demonstrate entanglement 24 using distance-two [[4,2,2]] code, simultaneously detecting errors correcting lost qubits. We also implement Bernstein-Vazirani algorithm up 28 encoded in [[4,1,2]] showing...
