Linear equations mod $n$ are pseudo-telepathic [2.3859169601259347]
We prove that the quantum monad in dimension $2n$ admits no natural transformation to the polymorphism clone of linear equations modulo $n$.<n>For every $ngeq 2$, there exists an unsatisfiable system of linear equations over $mathbbZ_n$ whose constraint system game admits a perfect finite-dimensional quantum strategy.

Between April 1 and May 15, 2026, a group of 49 mathematicians compiled a dataset of research-level mathematics questions with known answers.<n>We evaluate these questions in three stages: a single attempt by five state-of-the-art LLMs, a 20-runs-per-model evaluation, and a 3-run attempt with two heavy-thinking models.<n>After Stage 1, 41 questions remained completely unsolved; after Stage 2, this count dropped to 16; and we concluded Stage 3 with only 2 unsolved questions.

Thirty-six officers, artisanally entangled [0.7826806223782052]
A perfect tensor of order $d$ is a state of four systems maximally entangled under any bipartition. We present the first human-made order-$6$ perfect tensors. We sketch a formulation of the theory of perfect tensors in terms of quasi-orthogonal decompositions of matrix algebras.

The Power of Unentangled Quantum Proofs with Non-negative Amplitudes [55.90795112399611]
We study the power of unentangled quantum proofs with non-negative amplitudes, a class which we denote $textQMA+(2)$. In particular, we design global protocols for small set expansion, unique games, and PCP verification. We show that QMA(2) is equal to $textQMA+(2)$ provided the gap of the latter is a sufficiently large constant.

Machine learning detects terminal singularities [49.1574468325115]
Q-Fano varieties are positively curved shapes which have Q-factorial terminal singularities. Despite their importance, the classification of Q-Fano varieties remains unknown. In this paper we demonstrate that machine learning can be used to understand this classification.

Uncertainties in Quantum Measurements: A Quantum Tomography [52.77024349608834]
The observables associated with a quantum system $S$ form a non-commutative algebra $mathcal A_S$. It is assumed that a density matrix $rho$ can be determined from the expectation values of observables. Abelian algebras do not have inner automorphisms, so the measurement apparatus can determine mean values of observables.

$H_2$-reducible matrices in six-dimensional mutually unbiased bases [9.320472997908771]
Finding four six-dimensional mutually unbiased bases (MUBs) containing the identity matrix is a long-standing open problem in quantum information. We show that if they exist, then the $H$-reducible matrix in the four MUBs has exactly nine $2times2$ Hadamard submatrices. Our results represent the latest progress on the existence of six-dimensional MUBs.

An important variable in the 2017 analysis of Lovas and Andai, formally establishing the Hilbert-Schmidt separability probability conjectured by Slater of $frac2964$ for the 9-dimensional convex set of two-rebit density matrices, was the ratio ($varepsilon =fracsigmasigma1$) of the two singular values. Here, we investigate the behavior of the three singular value ratios of $V=Dfrac12 D-frac12$.
