Although quantum processors exist today, they are still a long way off from becoming practical replacements for classical computers. This is due to many practical considerations, not the least of ...

For more than a decade, scientists have been investigating ways to develop a “quantum battery” that stores energy using photons rather than electrons or ions. While quantum batteries—thanks to ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Quantum computing is poised to revolutionize various sectors, from pharmaceuticals to finance, by solving complex problems that are currently intractable for classical computers. This quantum ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated "Mpemba effects": counterintuitive cases where systems driven further from equilibrium relax ...

Computers, the internet and digitization have been major driving forces of innovation over the last 50 years, but classical computing architecture has its limits. Quantum computing is emerging as a ...

Google just debuted its latest quantum chip, Willow, which the tech giant claims can perform calculations in five minutes that would take the world’s fastest supercomputers 10 septillion years. For ...

Quantum computing, once hailed as a new advancement, has encountered significant challenges that have tempered early optimism. Sabine Hossenfelder explores the technical and practical obstacles that ...
