Abstract: In this paper, we propose a quantum algorithm that supports a real-valued higher-order unconstrained binary optimization (HUBO) problem. This algorithm is based on the Grover adaptive search ...

With growing focus on the existential threat quantum computing poses to some of the most crucial and widely used forms of encryption, cryptography engineer Filippo Valsorda wants to make one thing ...

Quantum computers pose a genuine long-term risk to bitcoin, but current fears often conflate wallet vulnerabilities with largely impractical threats to mining. New research finds that a quantum 51% ...

As quantum risk gains urgency, security vendors are turning PQC readiness into a structured market offering centered on discovery, inventory, and migration planning. Post-quantum cryptography (PQC) ...

A search problem refers to the task of finding a solution within some space of possible options, and that space could be made up of discrete steps or continuously varying values. For example, solving ...

As part of a major reform of the science sector, the government plans to set up a research organisation focused on emerging technologies, including quantum technologies. The first quantum revolution – ...

Why it matters: Researchers at Oxford University published a paper in Nature last week describing how they used quantum teleportation to transfer data between two quantum computers placed about two ...

2025 is an important year – it is probably our last chance to start our migration to post quantum cryptography before we are all undone by cryptographically relevant quantum computers. SecurityWeek’s ...

Accurate diagnostics form the foundation of effective medical treatment. Though highly developed, current diagnostic methods face limitations in processing the vast amount of patient-specific data ...
