Flavor in Ninths and a Discrete Gauge Origin of the QCD Axion

Vernon Barger · 2026

Quark and lepton hierarchies are organized by rational powers of a single parameter in units of one ninth. We show that this ``flavor in ninths'' structure points to a discrete $\mathbb{Z}_{18}$ gauge…

Impersonating Quantum Secrets over Classical Channels

Luowen Qian, Mark Zhandry · 2026

We show that a simple eavesdropper listening in on classical communication between potentially entangled quantum parties will eventually be able to impersonate any of the parties. Furthermore, the att…

Black-Box Separation Between Pseudorandom Unitaries, Pseudorandom Isometries, and Pseudorandom Function-Like States

Aditya Gulati, Yao-Ting Lin, Tomoyuki Morimae, Shogo Yamada · 2025

Pseudorandom functions (PRFs) are one of the most fundamental primitives in classical cryptography. On the other hand, in quantum cryptography, it is possible that PRFs do not exist but their quantum …

On the interim statistics for compact group characteristic polynomials and their derivatives

E. Bailey, S. Ortiz · 2025

The Keating-Snaith central limit theorem proves that $\Lambda_N(A)=\log\det(I-A)$, for randomly drawn $A\in \operatorname{U}(N)$, suitably normalised, tends to a complex Gaussian random variable in th…

On the Limitations of Pseudorandom Unitaries

Prabhanjan Ananth, Aditya Gulati, Yao-Ting Lin · 2025

Pseudorandom unitaries (PRUs), one of the key quantum pseudorandom notions, are efficiently computable unitaries that are computationally indistinguishable from Haar random unitaries. While there is e…

Pseudorandom Unitaries in the Haar Random Oracle Model

Prabhanjan Ananth, John Bostanci, Aditya Gulati, Yao-Ting Lin · 2025

The quantum Haar random oracle model is an idealized model where every party has access to a single Haar random unitary and its inverse. We construct strong pseudorandom unitaries in the quantum Haar …

The curious case of "XOR repetition" of monogamy-of-entanglement games

Andrea Coladangelo, Qipeng Liu, Ziyi Xie · 2025

In this work, we consider "decision" variants of a monogamy-of-entanglement game by Tomamichel, Fehr, Kaniewski, and Wehner [New Journal of Physics '13]. In its original "search" variant, Alice prepar…

Unified description of sum rules and duality between CP phases and unitarity triangles through third-order rephasing invariants

Masaki J. S. Yang · 2025

In this letter, we demonstrate that products of third-order rephasing invariants $V_{\alpha i} V_{\beta j} V_{\gamma k} / \det V$ of flavor mixing matrix $V$ reproduce all the nine angles of unitarity…

Dirac Representation for Lattice Spin Operators: Spin-$1/2$ and Spin-$1$ cases

Maseim Bassis Kenmoe · 2025

A novel quantum representation of lattice spin operators (LSOs) is achieved by mapping quantum spins onto their classical analogues for spin size $S=1/2$ and $S=1$. The "braket" representations of LSO…

Refining spectroscopic calculations for trivalent lanthanide ions: a revised parametric Hamiltonian and open-source solution

Juan-David Lizarazo-Ferro, Tharnier O. Puel, Michael E. Flatte, Rashid Zia · 2025

The historical calculation of spectroscopic properties for trivalent lanthanide ions is a complex multistep process that has been prone to inaccuracies. In this work, we revise the parametric semi-emp…
