Resonant and collective modification of London dispersion interactions under vibrational strong coupling

Marit R. Fiechter, Jeremy O. Richardson·Jun 30, 2026

Experiments have shown that, by tuning a microcavity to resonance with a vibrational mode of the molecules contained within it, one can modify chemical properties, such as reaction rates. This gives rise to the exciting prospect of steering chemical ...

Certifying quantum states without independence assumptions

Mariana Navarro, Leonardo Zambrano·Jun 30, 2026

Standard quantum verification and certification protocols often assume that experimental sources emit independent and identically distributed (i.i.d.) states. In realistic scenarios, however, temporal drift, memory effects, feedback, and correlated n...

Electrons on Helium and Entangled Quantum Sensors for Particle Physics

Maria Elena Perruzza, Niyaz R. Beysengulov, Stian D. Bilek +12 more·Jun 30, 2026

Quantum sensors that harness quantum coherence and entanglement are emerging as powerful tools in many fields, including particle physics, promising unprecedented sensitivity beyond classical detection methods. At the same time, electrons trapped on ...

Giant perpendicular Edelstein polarization in 2D compensated magnets via bichromatic Floquet driving

Mohsen Yarmohammadi, Daegeun Jo, Marco Berritta +3 more·Jun 30, 2026

While unconventional $p$-wave magnets can generate nonrelativistic Edelstein polarizations, spin-group symmetries strictly forbid these responses in unconventional magnets with higher-order harmonics, such as $d$-wave altermagnets. Here, we demonstra...

State-dependent Gaussian gate set using an optical tweezer for trapped ions

Philip Leindecker, Luka Milanovic, Tanja Behrle +5 more·Jun 30, 2026

We demonstrate a state-dependent Gaussian gate set on the motional modes of trapped $^{40}$Ca$^+$ ions, realized with an optical tweezer. Dynamic control of the tweezer intensity and position enables local displacement, squeezing, phase-space rotatio...

Generating uniform quantum state ensembles with continuous measurement

Theodore McKeever, Ahsan Nazir, Harry J. D. Miller·Jun 30, 2026

We investigate the generation of uniform quantum state ensembles via continuous measurement. Using the $SU(d)$ Bloch representation, we derive the associated Langevin and Fokker-Planck equations and identify geometric conditions under which homogeneo...

Automatic quantum function parallelization and memory management in Qrisp

Raphael Seidel·Jun 30, 2026

Automated optimization of quantum programs has gathered significant attention amidst the recent advances of hardware manufacturers. In this work we introduce a novel data-structure for representing quantum programs called permeability DAG, which capt...

Lazy-Move Compilation for Neutral-Atom Quantum Computers via a Buffer-Relay Fabric

Chen Huang, Jingbo Wang, Zhemin Zhang +5 more·Jun 30, 2026

Neutral atom quantum computing offers strong scalability and flexible qubit connectivity, but most existing compilation flows rely on reconfigurable atom arrays that physically shuttle qubit atoms during execution. Although this approach improves con...

Correlation-enhanced metrology from scrambling dynamics in a solid-state spin system

Yu-Chen Li, Shengyu Zhang, Ze Wu +6 more·Jun 30, 2026

Quantum information scrambling, the dispersal of local information into many-body degrees of freedom, provides a powerful mechanism for generating large-scale correlations and entanglement essential for quantum-enhanced metrology. However, experiment...

Correlation is magic in electronic structure Hamiltonians

Basie Seibert, Sam Alterman, Qingfeng Wang +3 more·Jun 30, 2026

The gate and qubit requirements of quantum computations of electronic structure have been extensively studied. However, the quantum resources present in electronic ground states, as measured by entanglement and magic, remain less well understood. We ...

Context-Verified, Error-Budget-Aware Decomposition Selection for Toffoli Networks

Karol Bartkiewicz, Patrycja Tulewicz·Jun 30, 2026

Two-qubit-gate error dominates the failure budget of near-term quantum circuits, so the decomposition chosen for each Toffoli (CCX) gate should minimize hardware two-qubit infidelity, not gate count. The cheapest decompositions - relative-phase and a...

Improving Perturbation Theory with the Sum-of-squares II: Large Density-Density Terms

Matthew B. Hastings·Jun 30, 2026

In Ref. 1, a method was given for self-consistently generating sum-of-squares decompositions of quartic fermionic Hamiltonians. Perturbation theory was used to generate a useful choice of cubic operators in this sum-of-squares. On a range of model pr...

Plasmon-Enabled High-Precision Single Molecule Localization Microscopy over an Extended Field of View

Muzzamal I. Shaukat, Carlos E. Rodriguez, M. Suhail Zubairy +1 more·Jun 30, 2026

We propose PIFLUX, a single-molecule localization scheme combining deep-subwavelength plasmonic illumination with widefield detection. Interference between counter-propagating gap plasmons and a normally incident optical field generates an illuminati...

Distributed Property Testing with (Quantum) Carrier Pigeons: Tight Bounds on State Certification

Kenny Chen·Jun 30, 2026

Recently, Doosti et al. introduced the problem of distributed quantum state verification, where $m$ distributed nodes are given a copy of an unknown state $ρ$, and can send limited one way communication to a central node, who has a complete descripti...

Signatures of the circular Unruh effect in electric and magnetic dipole transitions of multilevel atoms

Gregor Janson, Fabio Di Pumpo, Lorenz Thoma +1 more·Jun 30, 2026

The circular Unruh effect is the excitation of a detector moving along a planar circular trajectory within an electromagnetic vacuum. We demonstrate that the magnetic dipole transitions in an atom, acting as the detector, dominate the electric dipole...

Entangled photons from para-positronium decay: Do coincidences from scattered photons imply a Bell state?

Paul Joos, Peter Kling·Jun 30, 2026

Electron and positron can form a meta-stable bound state called positronium that decays via pair annihilation. We show how polarization-dependent Compton scattering can be used to verify that the two annihilation photons in the spin-zero case (para-p...

Holographic Krylov Complexity with Lifshitz Scaling and Hyperscaling Violation

Kazem Bitaghsir Fadafan, M. Reza Mohammadi Mozaffar·Jun 30, 2026

Following the holographic proposal that identifies the growth rate of Krylov complexity with the proper radial momentum of an infalling massive probe, we study Krylov complexity in Lifshitz and hyperscaling-violating backgrounds. For pure Lifshitz ge...
