Long Distance Daylight Drone-based Quantum Key Distribution under Relative Motion
Chun Zhou, Yanyang Zhou, Ping Wang +13 more·Mar 19, 2026
Low-altitude drones can serve as dynamic nodes apparently mitigating terrain-induced impacts for quantum networks. However, it is extremely hard to establish a sable quantum link in a drone-based dynamic platform, which requires centimeter-level posi...
Cavity Control of Strongly Correlated Electrons Beyond Resonant Coupling
Lukas Grunwald, Xinle Cheng, Emil Viñas Boström +4 more·Mar 19, 2026
Interfacing materials with electromagnetic cavities offers a route to modify equilibrium properties through structured vacuum fluctuations. The coupling of light with correlated electrons lacks a characteristic energy scale, making vacuum induced mod...
Gravitational Wave-Induced Scrambling Delay in SYK Wormhole Teleportation
Sudhanva Joshi, Sunil Kumar Mishra·Mar 19, 2026
Traversable wormhole teleportation in the Sachdev-Ye-Kitaev (SYK) model links quantum channel integrity to black hole interior dynamics, using teleportation fidelity to probe holographic scrambling. We subject the SYK boundary to a gravitational-wave...
Barren Plateaus Beyond Observable Concentration
Zi-Shen Li, Bujiao Wu, Xiao-Wei Li +1 more·Mar 19, 2026
Parameterized quantum circuits (PQCs) are central to quantum machine learning and near-term quantum simulation, but their scalability is often hindered by barren plateaus (BPs), where gradients decay exponentially with system size. Prior explanations...

Ding-An Chen, Kai-You Huang, Chun-Yen Hsu +3 more·Mar 19, 2026
The generation of a trapping potential for dark-state polaritons in a two-dimensional electromagnetically induced transparency system is theoretically studied. We show that such a trap can arise from a spatially inhomogeneous effective mass of the da...

Electromagnetically induced transparency (EIT) enables coherent light-matter storage, forming the basis of photonic quantum memories that are essential for scalable quantum networks and distributed quantum computing. However, accelerating the storage...
Observable-Conditioned Backaction in Dynamic Circuits: A Higher-Order Context-Conditioned Kernel for Local Dynamics
Petr Sramek·Mar 19, 2026
Mid-circuit measurements are essential primitives for dynamic circuits and quantum error correction, yet characterizing their induced disturbance on spectator qubits remains a central practical problem. Device-level benchmarking often compresses this...
Anderson transition in disordered Hatano-Nelson systems
Silvio Barandun·Mar 18, 2026
We illuminate the fundamental mechanism responsible for the transition between the non-Hermitian skin effect and defect-induced Anderson localization in the bulk via the study of Lyapunov exponents. We obtain a proof that the change of the topologica...
Continuous symmetry analysis and systematic identification of candidate order parameters for interacting fermion models
Cheng-Hao He, Yi-Zhuang You, Xiao Yan Xu·Mar 18, 2026
Symmetry plays a central role in modern physics, from classifying quantum states to characterizing phases of matter through spontaneous symmetry breaking. In interacting fermionic systems with multiple internal degrees of freedom, however, determinin...
Iterative Decoding of Stabilizer Codes under Radiation-Induced Correlated Noise
Anuj K. Nayak, Paul G. Baity, Peter J. Love +4 more·Mar 18, 2026
Fault-tolerant quantum computation demands extremely low logical error rates, yet superconducting qubit arrays are subject to radiation-induced correlated noise arising from cosmic-ray muon-generated quasiparticles. The quasiparticle density is unkno...

Ran Chen, Jiangchuan You, Alexey Vladimirovich Kulagin +2 more·Mar 18, 2026
The quantum Zeno and anti-Zeno effects describe how frequent measurements can either suppress or accelerate quantum dynamics. While extensively studied in various platforms, their manifestation in dark-state dynamics remains largely unexplored. Here ...

We explore the stability of a high-finesse optical cavity at 493 nm in vacuum for cavity QED with Barium ions. A high-finesse Fabry-Perot cavity is built using mirrors with high-reflectivity (HR) coatings that are implemented by stacking multiple thi...
Postselection induced localization and coherence in quantum walks on heterogeneous networks
Adithya L J, Suraj S Hegde, Chandrakala Meena·Mar 18, 2026
Postselection of quantum trajectories is known effectively introduce nonlinearity into dynamics of open quantum systems. We study the effect of such non-linearity in continuous-time quantum walks (CTQWs) on networks with homogeneous and heterogeneous...
