Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these transitions have primarily been studied in three-dimensional (3D) and ...

Faithful simulations of the world are impossible to create using ordinary computers. Simulating physical reality is, however, the original, express purpose of quantum computers. In 1981, long before ...

Researchers have pushed quantum chip design into a new era by simulating every physical detail before fabrication. Using a ...

An unprecedently large quantum simulator could shed light on how exotic, potentially useful quantum materials work and help us optimise them in the future. Quantum computers may eventually harness ...

An analog-digital approach to quantum simulation could lay the foundations for the next generation of supercomputers to finally outpace their classical predecessors. Reading time 3 minutes Quantum ...

Physicists have built a new type of digital-analogue quantum simulator in Google’s laboratory, which can be used to study physical processes with unprecedented precision and flexibility. Two ...

After decades of looking, researchers have seen a string of atoms go through a 1D phase change so elusive that it could only happen inside a quantum simulator. “One motivation [for our experiment] is ...

Did you know that China has invested over $15 billion in quantum computing research? This staggering figure highlights the intense global competition to lead in this groundbreaking technology. Quantum ...
