Chiral light from an emitter coupled to an achiral particle via the Purcell effect
Yining Xuan, Daito Miyazaki, Yuki Ishikawa +1 more·Oct 20, 2025
We demonstrate that non-chiral nanoparticles can produce chiral light when point emitters are coupled to their surface plasmon modes (SPMs) under certain conditions. Chiral emission arises from asymmetrical plasmon mode propagation from the source co...
Interplay of Noise and Reservoir-induced Decoherence in Persistent Currents
Samudra Sur, Thierry Giamarchi·Oct 20, 2025
Persistent current is a hallmark of quantum phase coherence. We study the fate of the persistent current in a non-equilibrium setting, where a tight-binding ring is subjected to stochastic disorder as well as a fermionic reservoir attached to each si...
Geometry-Driven Charge and Spin Transport in $\beta12$ Borophene Quantum Dots
Seyed Mahdi Mastoor, Amirhossein Ahmadkhan Kordbacheh·Oct 20, 2025
Theoretical research has been conducted to study how geometry affects charge and spin transport in $β\mathrm{12}$ borophene quantum dots, which are confined systems. The study examined two distinct central regions, which included a circular disc and ...
Kinetically-induced bound states in a frustrated Rydberg tweezer array
Mu Qiao, Romain Martin, Lukas Homeier +8 more·Oct 20, 2025
Understanding how particles bind into composite objects is a ubiquitous theme in physics, from the formation of molecules to hadrons in quantum chromodynamics and the pairing of charge carriers in superconductors. The formation of bound states usuall...
Resource efficient certification of system environment entanglement solely from reduced system dynamics
Jhen-Dong Lin, Pao-Wen Tu, Kuan-Yi Lee +4 more·Oct 20, 2025
Certifying nonclassical correlations typically requires access to all subsystems, presenting a major challenge in open quantum systems coupled to inaccessible environments. Recent works have shown that, in autonomous pure dephasing scenarios, quantum...
Mitigating Detuning-Induced Systematic Errors in Entanglement-Enhanced Metrology
Shingo Kukita, Yuichiro Matsuzaki·Oct 19, 2025
Quantum sensing leverages non-classical resources to enhance precision. In particular, Greenberger-Horne-Zeilinger (GHZ) states can, in principle, attain the Heisenberg limit that surpasses the standard quantum limit. While many studies have examined...
Temporal-order-driven asymmetric quantum interference and temporal coherence enhancement in spontaneous six-wave mixing
Da Zhang, Yu Zhang·Oct 18, 2025
Narrow-band multiphoton entanglement sources serve as a core enabling resource for advanced quantum information technologies. Recently, researchers have directly generated energy-time entangled triphoton W states in a hot atomic medium via spontaneou...
Dynamical control of quantum photon-photon interaction with phase change material
Chaojie Wang, Xutong Li, Xiuyi Ma +6 more·Oct 18, 2025
Quantum interference can produce a pivotal effective photon-photon interaction, enabling the exploration of various quantum information technologies that beyond the possibilities of classical physics. While such an effective interaction is fundamenta...
Emergent nonlocal interactions induced by quantized gauge fields in topological systems
Adel Ali, Alexey Belyanin·Oct 17, 2025
We study fermionic and bosonic systems coupled to a real or synthetic static gauge field that is quantized, so the field itself is a quantum degree of freedom and can exist in coherent superposition. A natural example is electrons on a quantum ring e...
Unravelling inter-channel quantum interference in below-threshold nonsequential double ionization with statistical measures
S. Hashim, C. Figueira de Morisson Faria·Oct 17, 2025
We present a systematic study of interchannel quantum interference in laser-induced nonsequential double ionization (NSDI) within the strong-field approximation. Focusing on the below-threshold intensity regime where the recollision-excitation with s...
Enhanced Secondary Electron Detection of Single Ion Implants in Silicon Through Thin SiO2 Layers
Ella B Schneider, Oscar G Lloyd-Willard, Kristian Stockbridge +7 more·Oct 16, 2025
Deterministic placement of single dopants is essential for scalable quantum devices based on group-V donors in silicon. We demonstrate a non-destructive, high-efficiency method for detecting individual ion implantation events using secondary electron...
Quantum State Designs via Magic Teleportation
Hugo Lóio, Guglielmo Lami, Lorenzo Leone +3 more·Oct 15, 2025
We investigate how non-stabilizer resources enable the emergence of quantum state designs within the projected ensemble. Starting from initial states with finite magic and applying resource-free Clifford circuits to scramble them, we analyze the ense...
Breaking of scale invariance in a strongly dipolar 2D Bose gas
Haoting Zhen, Yifei He, Sampriti Saha +4 more·Oct 15, 2025
Two-dimensional (2D) dipolar atomic gases present unique opportunities for exploring novel quantum phases due to their anisotropic and long-range interactions. However, the behavior of strongly dipolar Bose gases in 2D remains unclear, especially whe...
Hybrid light-matter boundaries of graphene in a chiral cavity
Volker Karle, Oriana K. Diessel, Vasil Rokaj +1 more·Oct 15, 2025
Recent advances in chiral cavities that can couple coherently to two-dimensional materials have opened a powerful route to reshape electronic topology without an external drive. Here we establish the bulk-boundary correspondence for graphene embedded...

Timothy Leese, Siobhan Patrick, Silvia Bergamini +1 more·Oct 15, 2025
We present a novel implementation of lambda-enhanced gray molasses cooling in a non-standard beam geometry and with an inexpensive laser locking set-up. In contrast to the established use of resource-intensive phase locking methods, our laser system ...

Tai Xiang, Yue-Hui Lu, Jacquelyn Ho +3 more·Oct 15, 2025
Ladder-type two-photon excitation of an atom from a ground state $|g\rangle$, to an intermediate excited state $|e\rangle$, and, finally, to a Rydberg state $|r\rangle$, has a variety of uses from quantum information to sensing. A common scheme for d...
