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 ...

Quantum computing could change the world. It could transform medicine, break encryption and revolutionise communications and artificial intelligence. Companies like IBM, Microsoft and Google are ...

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 ...

This ambiguity should give quantum computers true “superpowers”. At least in theory, quantum-based computers can perform calculations in fractions of a second that stump today's best supercomputers.

Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional ...

For centuries, humanity has sought to understand the fundamental laws governing the Universe. In the twenty-first century, that search has entered a new and unprecedented phase. Modern science now ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified picture of the Universe. GENEVA, SWITZERLAND ...
