Fifty-eight years after it first appeared, string theory remains the most popular candidate for the “theory of everything,” the unified mathematical framework for all matter and forces in the universe. This is much to the […]
The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University […]
The Post-Quantum Financial Infrastructure Framework (PQFIF), submitted to the U.S. Securities and Exchange Commission’s Crypto Assets Task Force, identifies the implementation project between QuSecure, Banco Sabadell, and Accenture as a primary benchmark for industry-wide adoption. […]
Insider Brief Dell Technologies introduced new security and cyber resilience capabilities designed to address converging threats from quantum computing and AI across its technology stack. The updates include quantum-ready protections at the firmware level, such […]
Conductor Quantum, a startup specializing in natural language interfaces for quantum computing, has introduced CODA MCP, a Model Context Protocol (MCP) server. The platform is designed to allow AI agents—such as Claude Desktop, VS Code, […]
Insider Brief Canada’s National Research Council is investing over $900 million through the Defence Industrial Strategy to support development and commercialization of defence and dual-use technologies, including quantum computing, communications, and sensing capabilities for the […]
Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum information, which can exist in multiple […]
Quantum 10, 2041 (2026). https://doi.org/10.22331/q-2026-03-23-2041 Quantum algorithms for linear systems produce the solution state $A^{-1}|brangle$ by querying two oracles: $O_A$ that block encodes the coefficient matrix and $O_b$ that prepares the initial state. We present […]
Quantum 10, 2040 (2026). https://doi.org/10.22331/q-2026-03-23-2040 While commonly used entanglement criteria for continuous variable systems are based on quadrature measurements, here we study entanglement detection from measurements of the Wigner function. These are routinely performed in […]
Quantum 10, 2039 (2026). https://doi.org/10.22331/q-2026-03-23-2039 Given an algorithm that outputs the correct answer with bounded error, say $1/3$, it is sometimes desirable to reduce this error to some arbitrarily small $varepsilon$ – e.g., if one […]
