Abstract: A general approach to obtain reduced models for a wide class of discrete-time quantum systems is proposed. The obtained models not only reproduce exactly the output of a given quantum model, ...

Computation pervades today’s world. From banking, to romance, to shopping, and even warfare, computers form one of the pillars of human civilization. However, there has been a lot of worry about ...

Whether you're playing poker against a single opponent or find yourself in a bidding war over a home purchase with another prospective buyer, you are operating under conditions of imperfect ...

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) ...

Department of Engineering Technology, Savannah State University, Savannah, GA, USA. Our analysis reveals that most claimed applications of Grover’s algorithm fall into one of several categories: Those ...

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 – ...

Data volumes are growing exponentially and performance expectations are at an all-time high, writing efficient code isn’t just a nicety—it’s a necessity. At the heart of code efficiency lies ...

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 ...
