In this paper, we study to what extent such a statement is true for linear-algebraic notions of expansion.\r\n\r\nThere are two well-studied notions of linear-algebraic expansion, namely, dimension expansion (defined in analogy to vertex expansion of graphs) and quantum expansion (defined in analogy to spectral expansion of graphs). Lubotzky and Zelmanov proved that the latter implies the former. We prove that the converse is false: There are dimension expanders which are not quantum expanders. This also answers in the negative questions of Lubotzky--Zelmanov and Dvir--Shpilka on the relation between dimension expansion and Kazhdan's property T.\r\n\r\nMoreover, this asymmetry is explained by the fact that there are two distinct linear-algebraic analogues of edge expansion of graphs. The first of these is quantum edge expansion, which was introduced by Hastings, and which he proved to be equivalent to quantum expansion. We introduce a new notion, termed dimension edge expansion, which we prove is equivalent to dimension expansion and which is implied by quantum edge expansion. Thus, the separation above is implied by a finer one: dimension edge expansion is strictly weaker than quantum edge expansion. This new notion also leads to a new, more modular proof of the Lubotzky--Zelmanov result that quantum expanders are dimension expanders."}],"citation":{"apa":"Li, Y., Qiao, Y., Wigderson, A., Wigderson, Y., &#38; Zhang, C.

Here, we design colloidal active rods capable of modulating their inner activity in response to crowding, thereby enforcing a primitive form of quorum sensing interactions. Through experiments, simulations, and theory we elucidate the impact of these interactions on the phase behavior of isotropic active matter. We demonstrate that, when conditioned to density, motility regulation can either lead to an absorbing phase transition, where all particles freeze their dynamics, or to atypical phase separation, where flat interfaces supporting a net pressure drop are in mechanical equilibrium. Fully active and fully arrested particles can then form heterogeneous patterns ruled by the competition between quorum sensing and mechanical interactions. Beyond the specifics of motile colloids, we expect our findings to apply broadly to adaptive active matter assembled from living or synthetic units.","lang":"eng"}],"citation":{"ama":"Lefranc T, Dinelli A, Fernández-Rico C, Dullens RPA, Tailleur J, Bartolo D.

While percolated networks of anisotropic particles have been explored at the nanoscale, achieving highly interconnected structures at the microscale remains challenging. In this work, we explore the controlled assembly of rod-like polymer colloids under external fields leading to reversible quasi-2D networks. By varying voltage and frequency, we modulate the pore size and thickness of the network. We find that field-driven attractive interactions enable percolation at lower area fractions than predicted for non-interacting rods. Monte Carlo simulations incorporating dipolar interactions and electrostatic boundary conditions confirm the field-induced transition from isotropic to aligned rod configurations, supporting the emergence of percolated networks. This work presents a simple and robust approach for assembling reconfigurable colloidal networks with controlled connectivity, offering new strategies for designing adaptive soft materials."}],"publication_identifier":{"eissn":["1744-6848"],"issn":["1744-683X"]},"article_processing_charge":"No","scopus_import":"1","language":[{"iso":"eng"}],"month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"None"},{"dataavailabilitystatement":"The data that support the findings of this article are openly available at https://github.com/hmis4/SurpassingLNTradeOffQKD; https://github.com/hmis4/SurpassingLNTradeOffQKD/tree/main/DomainEngineering  ","article_number":"024072","language":[{"iso":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","month":"08","scopus_import":"1","oa_version":"Published Version","title":"Surpassing the loss-noise robustness trade-off in quantum key distribution","ddc":["530"],"date_updated":"2026-07-16T08:27:32Z","publisher":"American Physical Society","_id":"20797","external_id":{"arxiv":["2412.08694"]},"acknowledgement":"We thank B.

Traditional QKD protocols require extensive noise compensation, hindering their industrial scalability and lowering the achievable key rates. Alternative protocols encode logical qubits in noise-resilient states but at the cost of using many physical qubits, increasing susceptibility to loss and limiting transmission distance. In this work, we introduce a logical-qubit encoding that uses antisymmetric Bell states in the continuous photonic degrees of freedom, frequency and time. By leveraging the continuous space, we overcome this noise-loss robustness trade-off by minimizing the number of photons per logical qubit while optimizing the encoding resilience over noise fluctuations. We analyze the security of our encoding and demonstrate its robustness compared to existing state-of-the-art protocols. This approach provides a path toward scalable, efficient QKD implementations under realistic noise conditions."}],"publication_identifier":{"eissn":["2331-7019"]},"doi":"10.1103/xq2l-r4r7","citation":{"mla":"Seabrook, Hannah, et al. “Surpassing the Loss-Noise Robustness Trade-off in Quantum Key Distribution.” <i>Physical Review Applied</i>, vol. 24, no. 2, 024072, American Physical Society, 2025, doi:<a href=\"https://doi.org/10.1103/xq2l-r4r7\">10.1103/xq2l-r4r7</a>.","apa":"Seabrook, H., Lavie, E., Strömberg, K.

A longstanding result of Birch states that there is a non-trivial integral solution to the equation F(x1,…,xn)=0 provided n>dimV∗F+(d−1)2d, and there is a non-singular solution in R and Qp for all primes p. We give a different formulation of this result. More precisely, we replace dimV∗F with a quantity HF defined in terms of the Hessian matrix of F. This quantity satisfies 0≤HF≤dimV∗F; therefore, we improve on the aforementioned result of Birch if HF<dimV∗F.
