Decentralized Coordination of Autonomous Traffic Through Advanced Air Mobility Corridors

Jasmine Jerry Aloor, Hamsa Balakrishnan·Jun 22, 2026

The use of dedicated corridors for Advanced Air Mobility (AAM) traffic is one of the most commonly proposed pathways to integrating them into existing airspace operations. Most prior research has focused on the design of networks of AAM corridors and...

Wavelet Matrix Product States for Quantum Fields

Molly Kaplan, Antoine Tilloy·Jun 22, 2026

We introduce a variational method to solve continuum quantum models with discrete tensor network techniques. The method leverages wavelet matrix product states (wMPS): matrix product states built on top of sufficiently regular ($N\geq 6$) Daubechies ...

Quantum turbulence in the many-body regime

Sayak Bhattacharjee, Mahendra K. Verma, Alexander V. Balatsky +1 more·Jun 22, 2026

We discuss phenomenology associated with turbulent hydrodynamics in quantum fluids from a condensed-matter perspective. We begin with weakly-interacting superfluids, often modeled by a mean-field theory governed by the Gross-Pitaevskii equation. Cons...

Revealing high-dimensional entanglement through symmetry

Jayden Webster, Florian Kanitschar, Emanuele Polino +5 more·Jun 22, 2026

Photons encoded in discrete time bins can be routinely prepared in temporal superposition states, enabling high-dimensional entanglement and enhanced quantum communication rates. However, characterizing this high-dimensional entanglement presents sig...

Universal Dynamical Response to Slow Driving in Chaotic Systems

Nachiket Karve, Nathan Rose, David Campbell +1 more·Jun 22, 2026

We propose a unified perspective on classical and quantum chaos based on the stability of a system's stationary states under slow driving. We probe this sensitivity via the system's susceptibility to the average protocol speed, which we call the ``sp...

Efficient Graph State Purification with Factorized Graph-Preserving Operations across Local Clifford Orbits

Mingyuan Wang, Guus Avis, Kenneth Goodenough +1 more·Jun 22, 2026

Graph states form a broad class of multipartite entangled states underlying measurement-based quantum computation, quantum networks, and stabilizer codes. However, systematic entanglement distillation for arbitrary graph states remains challenging be...

Infinite-Level Hierarchy of Solvable Quantum Circuits

Michael A. Rampp, Suhail A. Rather, Pieter W. Claeys·Jun 22, 2026

Dual-unitary circuits have emerged as a paradigm of exactly solvable yet non-integrable quantum dynamics. Recently, a generalization of dual unitarity attempting to extend the phenomenology of exactly solvable circuits has been introduced through a h...

Unitary Designs from Doped Matchgate Circuits

Fabian Ballar Trigueros, Zheng-Hang Sun, Xhek Turkeshi +2 more·Jun 22, 2026

Matchgate circuits realize free-fermion dynamics: they are efficiently classically simulable, yet cannot on their own generate the generic randomness required for universal computation or unitary design formation. We study a controlled route beyond t...

Fermi surface change and $d$-wave superconductivity in the square lattice Kondo-Heisenberg model

Alexander Nikolaenko, Riccardo Rende, Luciano Loris Viteritti +2 more·Jun 22, 2026

We study the two-dimensional Kondo-Heisenberg model on a square lattice, with the conduction electrons away from half-filling, using neural network quantum states. Mapping the ground-state phase diagram as a function of the Kondo and Heisenberg coupl...

A no-go theorem for privacy in distributed sensing using Gaussian states

Jason L. Pereira, Damian Markham·Jun 22, 2026

In the discrete variable setting, entangled resource states allow a set of parties to learn a global function of a set of spatially separated systems, whilst keeping the local parameters of those systems completely private. In the continuous variable...

Controlled Chaos in 4D SCFTs

Florent Baume, Atakan Çavuşoğlu, Vivek Chakrabhavi +1 more·Jun 22, 2026

Chaotic dynamics play an important role in a number of physical systems. One of the qualitative hallmarks of this behavior is the appearance of a sufficiently "complex" spectrum of energy levels. This also makes it challenging to directly verify the ...

Connecting Quantum Tomography and Quantum Retrodiction

Sebastian Murk, Ian Tan, Fabian Müller +1 more·Jun 22, 2026

Quantum tomography and quantum retrodiction are traditionally viewed as separate inference tasks: tomography reconstructs quantum states from measurement data, whereas retrodiction infers past quantum states from observed outcomes. We show that the t...

Emergent Andreev Reflection from a Lattice Duality Defect

Atsushi Ueda, Tokiro Numasawa, Boris De Vos +1 more·Jun 22, 2026

Andreev reflection converts an incoming fermion into an outgoing hole and is usually tied to a superconducting interface. We show that an analogous charge-conjugating boundary condition emerges from a purely lattice duality defect. Starting from a Ma...

Robust Structure Learning of $k$-local Lindbladians

Tim Möbus, Thiago Bergamaschi, Daniel Stilck França +1 more·Jun 22, 2026

We present an efficient protocol for learning an unknown $k$-local Lindblad generator on $n$ qubits using only product-state preparations, short-time evolution, and single-qubit Pauli measurements, without prior knowledge of the interaction structure...

Multi-scale reconstruction of single-ion damage tracks in diamond via nitrogen-vacancy centers

Daniel G. Ang, Jiashen Tang, Maximilian Shen +9 more·Jun 22, 2026

Understanding particle-induced damage tracks in solid-state materials underpins emerging applications in rare-event detection and quantum defect engineering. Resolving these tracks requires multi-scale readout, from event localization at the millimet...

Log-concavity and tunneling: adiabatic quantum optimization for convex functions (with a spike)

Arthur Braida, Elie Bermot, Simon Apers·Jun 22, 2026

Quantum tunneling is expected to provide a computational speedup in quantum computing, a phenomenon that Adiabatic Quantum Optimization (AQO) aims to leverage. While some academic proofs of concept have been studied, such as the "Hamming weight with ...

Random dimension reduction and learning symmetric properties of quantum states

Angus Lowe, Xinyu Tan·Jun 22, 2026

We introduce a procedure called random dimension reduction that simultaneously reduces the dimensions of many, potentially distinct quantum states while preserving properties invariant under the tensor power action of an isometry. This provides a bla...

Decentralized Autonomous Traffic Management through Corridor Networks

Jasmine Jerry Aloor, Aadarsh Govada, Hamsa Balakrishnan·Jun 22, 2026

As autonomous aircraft are introduced at scale and traffic density increases, centralized management becomes insufficient to coordinate the large numbers of crewed and uncrewed aircraft. Dedicated Advanced Air Mobility (AAM) corridors have therefore ...
