Two-Round Even-Mansour Is Quantum-Secure in the Ideal Permutation Model

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, In a dead-black void, a single massive gyroscopic core made of two interlocking rings of polished obsidian and raw quicksilver spins in opposite directions, their inner edges etched with countless mirrored facets that catch and scatter light like an impossible lock; a single cold beam of white light slices down from above, flaring off the ring edges into razor-thin silver glints; speed lines radiate outward from the core and dissolve into infinite darkness; the atmosphere is one of silent, absolute, unbreakable closure. [Z-Image Turbo]

An open question in the construction of quantum-secure block ciphers has been answered. A paper now in circulation proves that the two-round Even-Mansour cipher, which interleaves public permutations ...

ArXiv paper reports optimal Θ(κ√d log(1/ε)) query complexity for quantum linear systems

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, A single monumental spindle of blackened steel and obsidian glass, its surface wrapped in a helix of dozens of knife-thin fins radiating outward, each fin etched with hairline grooves that catch the light, standing alone in a pitch-black void. A solitary shaft of rim light from the left rakes across the fins, creating razor-sharp highlights and deep shadowed valleys, while concentric speed lines of faint blue-white light stream outward from the spindle's central axis, conveying swift, inevitable motion. The atmosphere is one of tense equilibrium, the spindle vast in scale, surrounded by emptiness that amplifies its stark precision. [Z-Image Turbo]

A paper posted to the arXiv reports an optimal algorithm for the quantum linear systems problem, according to its abstract. The paper's claim is that the query complexity of the problem is Θ(κ√d log(1...

THE RADIANT PEROVSKITE ELECTUARY: A Sovereign Cure Against the Frozen Nerves of the Age

Authentic 1890s Victorian patent medicine advertisement, ornate decorative border with scrollwork and flourishes, bold Victorian serif typography headline reading "PEROVSKITE ELECTUARY", subtitle "A Sovereign Cure Against the Frozen Nerves of the Age" in smaller elegant type, central illustration of a crystal-stoppered glass phial with luminous amber liquid and faint geometric sparkles, flanked by ornamental text boxes containing refined medical claims, price "2s 11d per crystal-stoppered phial" in a small badge, aged sepia paper texture with halftone dot printing effect, Victorian commercial advertising aesthetic, single ad composition, no newspaper columns or surrounding articles [Nano Banana]

A most afflicting disorder has established itself among the studious: nerves harden, thoughts refuse to flow. The PEROVSKITE ELECTUARY, prepared by Professor M. Zangwill, late of the Samarkand Institu...

Protocols for Classically Verifiable Quantum Advantage via Quantum Indistinguishability Obfuscation

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, Extreme close-up of a shattered mirror's epicenter, radial speed lines of fractured glass screaming outward like frozen lightning, each shard a razor-sharp silver sliver catching a separate fragment of an empty white void, yet all together they reassemble into a single seamless reflection of a distant star, surfaces alternating between crystalline sharpness and smooth obsidian, harsh chiaroscuro lighting from the upper left, stark black background swallowing all negative space, atmosphere of tense suspension before the next shatter, the broken mirror alone as the dynamic subject [Z-Image Turbo]

The first of October brings to the repository a paper that addresses one of the rarer questions in the cryptographic trade: how a witness who commands only classical instruments may be satisfied that ...

The Lower Bound of Leaked Transaction Size Sets the Exact Threshold for Profitable Sandwich Attacks

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, A single taut tripwire of polished obsidian and chrome, stretched across a pitch-black void, with a tiny etched mark at its exact center glowing molten red, speed lines radiating outward from the mark in all directions, harsh side lighting casting jagged shadows, stark high-contrast composition, atmosphere of precarious tension and imminent snap [Z-Image Turbo]

A paper posted to the arXiv offers an exact answer to a question private transaction pools have until now addressed by concealment rather than arithmetic: how much leakage still makes a sandwich attac...

Seven Million Signatures: Frame's Quantum-Resistant Testnet Enters Private Beta

black and white manga panel, dramatic speed lines, Akira aesthetic, bold ink work, A colossal circular seal, twenty feet in diameter, forged from black obsidian laced with luminous platinum veins, its rim etched with seven million microscopic signatures that flicker with faint golden light. The center is a swirling vortex of white-hot energy, as if the seal is cracking open under immense pressure. Speed lines radiate from the vortex, streaking outward into an infinite black void. Dramatic side lighting carves deep shadows across the seal's fractured surface, each signature catching a sharp glint. The atmosphere is charged, silent, monumental — a gateway tested against an unseen storm. [Z-Image Turbo]

The long migration of signatures has a new claimant to permanence. The Crypto Company this day opened the private beta of Frame, its quantum-resistant Layer 1 blockchain, with more than seven million ...
