The New Golden Age of Archaeology Is Right Now

صورة
Narrowing her eyes , keen with years of research and experience, Sarah Parcak squints past the dust and sand. Hands out, Egypt's vast landscape at her fingertips, she's searching for clues that will lead her to something extraordinary, buried and missing for thousands of years. She and her team have been exploring the land for more than a year, looking for a settlement or structure that uncovers the ancient capital of Tanis. No one knows what it looks like, but Parcak has an idea. And she's getting close. Then suddenly, at the northeast region of the Nile Delta, administrative buildings, streets, palaces and houses of all sizes surface before her eyes. Parcak is excited. She has found Tanis. But she isn't actually in Egypt — she's thousands of miles away in her lab in Alabama, staring at processed, false color satellite imagery. It's an emerging trend in archaeology that enables people to make extremely important archaeological finds — before excavatin...

What's Wrong With Quantum Computing

صورة
Basic Bits First things first, a quick reminder of  exactly what a quantum computer is . Essentially, they’re computers that make use of quantum physics. Unlike a normal digital systems which rely on data encoded into binary digits (bits)—that can only ever take the form of 0 or 1—quantum computation uses quantum properties to represent data and perform operations. Building Blocks  You've heard plenty of people by now—including us—banging on about quantum computers, and how they’re the future of high-performance computing. Quantum computing, we're meant to understand, is set to change the world. But despite its promise, it's neither widely available nor particularly useful yet. Here's why not. A quantum computer, then, uses not bits but qubits (quantum bits). Each of its qubits can represent a 0, a 1, or—crucially—anything in between. Imagine a table covered in coins. In a classical computer, each one is either showing a head or tail; in a quantum co...
